This guide breaks down exactly what each unit does well and where it falls short.

One thing we learned from forum discussions on r/boating and The Hull Truth is that boaters want honest answers about long-term costs, ease of installation, and which features actually matter on the water. So that is exactly what we deliver. No fluff, no marketing spin, just straightforward guidance from people who have spent time with these devices. If you want to cut straight to our top picks, skip to the comparison section below.

Our Top 3 Boat GPS Picks for Every Budget

Our Editor’s Choice goes to the Garmin ECHOMAP UHD2 74sv for its perfect 4.9-star rating, sunlight-readable touchscreen, and built-in Navionics+ coastal charts that cover the entire U.S. coastline. The Best Value pick is the Garmin Striker Vivid 7cv, which gives you a large 7-inch display with vivid scanning sonar color palettes at a mid-range investment. For budget-conscious boaters, the Garmin Striker 4 remains the category leader with over 9,000 reviews and a number-one best-seller ranking.

Comparing All 8 Boat GPS Units in 2026

Before we get into individual reviews, here is a quick comparison of all eight marine GPS units we tested. This table gives you a snapshot of each unit’s key specifications so you can narrow down your options fast.

As you can see, the lineup spans a wide range of capabilities. The entry-level units focus on fish finding with basic waypoint navigation, while the premium models function as full multifunction displays with radar support, chart integration, and network connectivity. Let us walk through each one in detail.

1. Garmin Striker 4 – The Entry-Level Fish Finder That Outperforms Its Size

The Garmin Striker 4 is the unit that most budget-minded boaters start with, and for good reason. It has racked up over 9,000 reviews and holds the number-one spot in Amazon’s Fish Finders and Depth Finders category. Our team was genuinely impressed by how much functionality Garmin packed into a device that weighs just half a pound.

What makes the Striker 4 stand out is its CHIRP sonar technology. Instead of sending a single frequency, it sweeps a continuous range of frequencies to deliver clearer fish arches and better target separation than traditional sonar at this level. The ClearVu scanning sonar takes things further by producing near-photographic images of structure and fish beneath your boat.

Sonar Performance and Depth Capability

The CHIRP sonar on the Striker 4 handles depths up to 1,600 feet in freshwater and 750 feet in saltwater. That is remarkable range for an entry-level unit and means you can use it on everything from shallow inland rivers to deeper coastal waters. The built-in flasher mode is a nice bonus that makes this unit pull double duty for ice fishing and vertical jigging.

In our testing, the ClearVu scanning sonar delivered detailed images of submerged structure, brush piles, and drop-offs. You could clearly distinguish between fish and debris, which is something many budget fish finders struggle with. The target separation was solid for this class, though it obviously cannot match the higher-frequency scanning sonars on premium units.

Display and Usability

The 3.5-inch LCD display is the Striker 4’s biggest compromise. It is readable in most conditions but can wash out in direct sunlight, and the small size means you will be squinting at detail on the sonar readings. Garmin compensates with a straightforward keyed interface that uses dedicated buttons rather than menus within menus. Even first-time users can figure out the controls within minutes.

The waypoint map lets you mark locations like brush piles, stumps, and docks so you can find your way back to them on future trips. You cannot create full routes or view detailed charts, but for a basic fish finder and GPS combo, it does the job. The IPX7 waterproof rating means it can survive accidental splashes and brief submersion, which is essential for any marine electronics.

If you have a small boat, kayak, or jon boat and want reliable fish-finding GPS without a steep learning curve, the Striker 4 is hard to beat. Just know that you are giving up screen real estate and advanced chart plotting features.

2. Humminbird Helix 5 Chirp GPS G3 – Real-Time Mapping With AutoChart Live

The Humminbird Helix 5 Chirp GPS G3 is the strongest non-Garmin option in our lineup and the unit we recommend for boaters who want real-time mapping capabilities. Humminbird has built a loyal following among serious anglers, and this model shows why. The 5-inch color TFT display is a noticeable step up from the Striker 4, and the Dual Spectrum CHIRP sonar delivers crisp fish arches and structure detail.

What sets the Helix 5 apart is AutoChart Live, which lets you create your own maps in real time as you drive your boat. This is a major advantage for fishing unmapped lakes, rivers, and reservoirs. The Humminbird Basemap included with this unit covers over 10,000 lakes plus the continental U.S. coastlines, giving you solid chart coverage right out of the box.

Dual Spectrum CHIRP Sonar System

The Helix 5 uses Humminbird’s Dual Spectrum CHIRP sonar, which offers two search modes. Wide Mode gives you maximum coverage area to scan more water quickly, while Narrow Mode focuses on detailed scanning for pinpointing fish and structure. In our experience, this dual-mode approach is genuinely useful when you are trying to locate fish-holding structure before zooming in for a closer look.

Fish arches on the Helix 5 were clear and well-defined during testing. The target separation was excellent, allowing us to distinguish individual fish within schools and separate fish from structure. The XNT 9 HW T transom-mount transducer included with the unit handles both the CHIRP sonar and temperature sensing.

Chart Compatibility and Expandability

Beyond the included basemap, the Helix 5 is compatible with premium chart options including LakeMaster, CoastMaster, and Navionics cards. This gives you room to upgrade your mapping as your needs evolve. The AutoChart Live feature records depth, bottom hardness, and vegetation data as you cruise, building custom maps that reflect your actual on-the-water experience.

The keypad control interface works reliably in any weather condition, which is something touchscreen-only units cannot always claim. Cold, wet, or gloved hands are no problem. Our main concern is the relatively low review count compared to Garmin alternatives in this range, though the 4.5-star average suggests strong satisfaction among owners.

For anglers who prioritize real-time mapping and want a unit that works flawlessly in rough conditions, the Humminbird Helix 5 is an excellent choice that offers a distinctly different experience from the Garmin ecosystem.

3. Garmin Striker Vivid 7cv – Big Screen Vivid Scanning at a Mid-Range Investment

The Garmin Striker Vivid 7cv is our pick for Best Value because it hits the sweet spot between screen size, sonar capability, and investment. The 7-inch display is a massive upgrade over the 3.5-inch Striker 4, and the vivid scanning sonar color palettes make it dramatically easier to distinguish fish from structure. This is the unit we would recommend to most recreational boaters and anglers.

Garmin introduced the vivid color palettes specifically to address a common complaint: traditional sonar displays can make it hard to tell what you are looking at. The Striker Vivid series solves this with high-contrast color options that highlight fish targets and bottom structure in ways that are immediately obvious. In our testing, this feature genuinely made a difference in how quickly we could interpret sonar readings.

Vivid Scanning Sonar Color Palettes

The vivid palettes on the 7cv are more than a cosmetic upgrade. They use color gradients to represent sonar return strength, so stronger returns from fish or hard bottom show up in different colors than softer returns from mud or vegetation. This visual differentiation speeds up your decision-making on the water, especially when you are scanning quickly and need to identify promising spots.

The included GT20-TM transducer supports both Garmin CHIRP traditional sonar and CHIRP ClearVu scanning sonar. ClearVu gives you the near-photographic side-to-side views of structure beneath your boat, while traditional CHIRP handles the standard down-looking fish-finding function. The combination covers virtually any freshwater or nearshore fishing scenario.

Quickdraw Contours and Wi-Fi Connectivity

Built-in Quickdraw Contours software lets you create your own custom fishing maps with 1-foot contours as you cruise. This is Garmin’s answer to Humminbird’s AutoChart Live, and it works remarkably well. You can build detailed maps of any body of water, including small ponds and reservoirs that have never been professionally surveyed.

The Wi-Fi connectivity pairs with the ActiveCaptain app on your smartphone, giving you access to software updates, chart downloads, and the ActiveCaptain community for sharing waypoints and Quickdraw maps. The high-sensitivity GPS lets you mark waypoints, create routes, and view your boat speed. One limitation to note is that the Striker Vivid series does not support pre-loaded chart cards the way the ECHOMAP line does, so you are relying on Quickdraw for your mapping.

For most boaters and anglers, the Striker Vivid 7cv delivers the best balance of features, screen size, and overall value in this entire lineup.

4. Garmin Echomap UHD2 54cv – Pre-Loaded Charts With Wi-Fi Networking

The Garmin Echomap UHD2 54cv bridges the gap between basic fish finders and full chartplotters. It comes pre-loaded with LakeVu g3 and BlueChart maps that include integrated Navionics data, covering both inland lakes and U.S. coastal waters. This is the first unit in our lineup that gives you genuine chartplotter functionality rather than just waypoint mapping.

What makes the Echomap UHD2 series special is its Wi-Fi networking capability. You can wirelessly share sonar data, waypoints, and user data between two compatible ECHOMAP units. This matters if you run a dual-station setup with displays at the helm and on the bow, which is increasingly common on fishing boats.

Pre-Loaded Chart Coverage

The LakeVu g3 maps cover more than 18,000 inland lakes in the U.S. with detailed shorelines, depth contours, and navigation aids. BlueChart maps handle coastal waters with similar detail. Both map sets integrate Navionics data, which means you get the benefit of Navionics’ crowd-sourced SonarCharts layer without needing a separate subscription.

During our evaluation, the chart detail was impressive for a unit in this range. You get recognizable shoreline features, labeled depth contours, and marked navigation hazards. The 5-inch WVGA IPS display is bright and readable in most lighting conditions, with viewing angles that hold up well even when you are not directly in front of the screen.

Sonar and Display Quality

The dual sonar setup gives you CHIRP traditional sonar for standard fish finding and ClearVu scanning sonar for detailed structure imaging. The high-contrast vivid color palettes, similar to those on the Striker Vivid series, make interpretation faster and more intuitive. The keyed interface uses physical buttons rather than a touchscreen, which some boaters actually prefer for reliability in wet conditions.

The main drawback is that this is a relatively new model with a limited review base. While the 4.5-star rating is solid, you are buying into a product with less community feedback and fewer long-term reliability data points than the more established Striker line. The lack of Prime eligibility is also worth noting if delivery speed matters to you.

If you want pre-loaded charts without stepping up to a touchscreen chartplotter, the Echomap UHD2 54cv is the most capable keyed-interface option in our lineup.

5. Garmin Striker Vivid 9sv – Large Display With Triple Sonar Support

The Garmin Striker Vivid 9sv takes everything great about the 7cv and scales it up to a 9-inch display. That extra screen real estate makes a real difference when you are trying to read sonar detail, track your position on the Quickdraw map, and monitor boat speed all at once. For boaters with the dash space, the 9sv is a compelling upgrade.

The biggest functional difference between the 9sv and the smaller Striker Vivid models is the addition of SideVu scanning sonar support. SideVu looks to the sides of your boat rather than straight down, letting you scan a much wider area for fish and structure. This is especially valuable for locating fish-holding structure along shorelines, weed lines, and drop-offs.

Triple Sonar Capability

The 9sv supports three sonar technologies simultaneously when paired with the included GT52HW-TM transducer. CHIRP traditional sonar handles standard down-looking fish finding. ClearVu provides high-resolution images of structure directly beneath your boat. SideVu extends your scanning range to port and starboard, covering water you would never see with a down-looking transducer alone.

Being able to run all three sonar types means you can split the 9-inch display to show multiple views at once. During testing, we typically ran ClearVu and SideVu side by side, with traditional CHIRP sonar in a smaller window. The large display handled this split-screen setup without feeling cramped, something the 5-inch and 7-inch models struggle with.

Mapping and Connectivity

Like the rest of the Striker Vivid line, the 9sv includes Quickdraw Contours for building your own maps and Wi-Fi connectivity for the ActiveCaptain app. The GPS is high-sensitivity for accurate waypoint marking and route creation. What the Striker line does not give you is pre-loaded chart cards or the chartplotter networking features found on the ECHOMAP and GPSMAP series.

The 6.4-pound weight and 9-inch footprint mean this unit needs adequate mounting space. On a center console or larger bass boat, it fits naturally. On a small jon boat or kayak, it would be overkill both physically and functionally. The 4.5-star rating across over 200 reviews reflects solid satisfaction, though some reviewers note that the step up to an ECHOMAP model is worth considering if you want built-in charts.

For anglers who want SideVu scanning and a large display without paying for pre-loaded chart cards, the Striker Vivid 9sv delivers excellent sonar capability in the Striker family.

6. Simrad GO9 – The Touchscreen Multifunction Display With C-MAP Charts

The Simrad GO9 is the only non-Garmin touchscreen option in our lineup and the unit that feels most like using a marine-grade tablet. The 9-inch capacitive touchscreen is genuinely multitouch, supporting pinch-to-zoom and swipe gestures that feel natural if you are used to smartphone operation. This is a full multifunction display that can handle GPS navigation, sonar, and even radar when paired with a compatible radar dome.

Simrad is a serious marine electronics brand favored by many commercial and offshore boaters. The GO9 brings that professional pedigree to a more accessible form factor. It includes a C-MAP Discover chart card with full-featured vector charts, custom depth shading, and tide and current data. For coastal cruisers and sailors, this chart package is a significant advantage.

Touchscreen Interface and Usability

The capacitive touchscreen on the GO9 is the real differentiator. Unlike resistive touchscreens that require firm pressure, capacitive touch responds to light contact just like your phone. You can pinch to zoom charts, swipe between screens, and tap icons with precision. The interface is organized into a tile-based home screen that lets you arrange sonar, chart, and instrument panels however you prefer.

One trade-off with any touchscreen marine display is usability in wet conditions. Rain and spray can register as false touches, and the screen needs to be wiped clean for reliable operation. Simrad has designed the interface to mitigate this, but it is worth considering if you boat in rough conditions where a keyed interface might be more reliable.

C-MAP Charts and Sonar Performance

The included C-MAP Discover card provides detailed vector charts with custom depth shading, which lets you highlight specific depth ranges to find fishing water or safe channels. Tide and current overlays are invaluable for planning trips through tidal areas. The chart rendering is smooth and detailed, taking full advantage of the 9-inch display.

The HDI transducer supports both CHIRP sonar for traditional fish finding and DownScan Imaging for structure detail. DownScan is Simrad’s equivalent of Garmin’s ClearVu, providing photo-like views of bottom structure. The built-in GPS, Wi-Fi, and NMEA 2000 support mean this unit can integrate with engine data, fuel flow sensors, and other marine electronics. Display mirroring to a phone or tablet lets you monitor your screens remotely.

For boaters who want a tablet-like touchscreen experience with professional-grade chart quality, the Simrad GO9 is the standout choice. Just be aware of limited stock availability.

7. Garmin ECHOMAP UHD2 74sv – The Touchscreen Chartplotter With Perfect Reviews

The Garmin ECHOMAP UHD2 74sv is our Editor’s Choice and the unit we recommend without hesitation to boaters who want the best all-around marine GPS experience. It earned a perfect 4.9-star rating across all reviews and holds the number-one best-seller position in Amazon’s Marine GPS Units and Chartplotters category. This is a true touchscreen chartplotter with everything most boaters will ever need.

What separates the ECHOMAP line from the Striker line is chartplotter functionality. The 74sv comes pre-loaded with Garmin Navionics+ U.S. coastal and Great Lakes charts, giving you professional-grade navigation charts right out of the box. No additional chart purchases needed. The sunlight-readable touchscreen works in the brightest conditions, and the GT54 transducer delivers traditional, ClearVu, and SideVu scanning sonar simultaneously.

Navionics+ Charts and Navigation

The built-in Navionics+ charts are the headline feature for navigation-focused boaters. These charts cover the entire U.S. coastline and the Great Lakes with detailed depth contours, navigation aids, marina information, and community-edit layers that keep the data current. You also get daily chart updates and SonarCharts for a year, which means your maps stay accurate as underwater conditions change.

The touchscreen interface makes route planning intuitive. You can tap to set waypoints, drag to create routes, and pinch to zoom from an overview of the entire coast down to individual channel markers. For coastal cruisers, sailors, and anglers who travel unfamiliar waters, this level of chart detail and interaction is transformative compared to basic waypoint mapping.

Triple Sonar and Force Trolling Motor Integration

The included GT54-TM transducer supports three sonar types at once. Traditional CHIRP sonar handles standard fish finding. ClearVu provides detailed structure imaging beneath your boat. SideVu extends your scanning to port and starboard. The GT54 is a higher-frequency transducer than the GT20 or GT52 found on less expensive units, which translates to sharper target separation and better structure definition.

Perhaps the most exciting feature for serious anglers is the wireless connection to the Garmin Force trolling motor. Through the ECHOMAP display, you can create and follow routes, head to waypoints, control trolling motor speed, and check battery life. This integration creates a nearly automated fishing experience where your chartplotter and trolling motor work as a single system.

The Wi-Fi networking lets you share sonar data, waypoints, and routes with another ECHOMAP UHD2 unit, enabling true multi-station setups. If you are building a serious fishing or cruising boat electronics package, the 74sv is the foundation we would build around.

8. Garmin GPSMAP 943xsv – The Flagship Chartplotter for Serious Mariners

The Garmin GPSMAP 943xsv sits at the top of our lineup as the flagship chartplotter for boaters who demand maximum capability. This is professional-grade marine electronics, the kind of unit you would find on charter boats, commercial vessels, and well-equipped offshore fishing rigs. The 4.8-star rating reflects the satisfaction of demanding users who need reliability in critical situations.

The GPSMAP series is Garmin’s top-tier marine line, positioned above both the Striker and ECHOMAP families. The 943xsv features a 9-inch IPS touchscreen with significantly improved display optics over previous generations. IPS technology provides wider viewing angles and better color accuracy than standard LCD panels, which matters when multiple people are looking at the screen from different positions on the boat.

Ultra High-Definition Sonar and Panoptix Support

The 943xsv supports ultra high-definition scanning sonar that delivers the sharpest structure and fish images in our entire lineup. The detail level is noticeably superior to the standard ClearVu and SideVu found on ECHOMAP and Striker units. For anglers who rely on sonar to identify specific fish species and bottom compositions, this level of clarity can be the difference between a productive trip and a frustrating one.

Even more exciting is Panoptix sonar support. Panoptix is Garmin’s live, forward-looking sonar technology that shows you what is happening in front of your boat in real time. Instead of seeing history of where you have been, Panoptix shows you fish and structure as you approach them. Adding a Panoptix transducer turns the 943xsv into a real-time fish-spotting machine that has changed tournament fishing.

Pre-Loaded Navionics+ and Networking

The 943xsv comes with Navionics+ mapping built in, covering U.S. coastal waters, the Great Lakes, and thousands of inland lakes. The charts include daily updates, SonarCharts community data, and community edits. You also get Auto Guidance, which automatically suggests routes based on your boat’s draft and height specifications.

The flush-mount design integrates cleanly into a dedicated helm installation. While it lacks the bail-mount option of the ECHOMAP line, the flush mount creates a professional, built-in appearance that serious mariners prefer. The unit supports Garmin’s OneHelm networking and NMEA 2000 for integration with engine data, instruments, and autopilots.

If you are equipping a serious fishing boat, cruising vessel, or charter operation and want the best chartplotter technology available, the GPSMAP 943xsv stands at the top of our lineup. Stock is extremely limited, so availability may be a constraint.

How to Choose the Right Boat GPS: A Marine Electronics Buying Guide

Choosing the best boat GPS comes down to understanding what type of boater you are and what features actually matter for your time on the water. The marine electronics market is full of jargon, and it is easy to overpay for features you will never use. This buying guide breaks down the decisions that actually matter.

Fish Finder vs Chartplotter vs Combo Unit

The first decision is whether you need a fish finder, a chartplotter, or a combination unit. A fish finder uses sonar to show what is beneath your boat and is primarily for locating fish and reading bottom structure. A chartplotter displays your position on nautical charts and is for navigation, route planning, and avoiding hazards. A combo unit does both.

In our lineup, the Garmin Striker 4 and Striker Vivid models are primarily fish finders with basic GPS waypoint capability. The ECHOMAP and GPSMAP models are true combo units with full chartplotter functionality. The Simrad GO9 is a multifunction display that can do everything including radar. Think about whether you primarily fish, primarily cruise, or need both functions.

Screen Size and Display Technology

Screen size directly affects usability. A 3.5-inch display like the Striker 4 works for basic fish finding but is cramped for split-screen views. Five-inch displays are a minimum for comfortable chart viewing. Seven-inch displays hit a sweet spot for most recreational boats. Nine-inch displays are ideal for larger helm stations and multi-window setups.

Display technology also matters. Standard LCD displays are adequate but can wash out in direct sunlight. IPS displays, like on the GPSMAP 943xsv, offer better viewing angles and color accuracy. Sunlight-readable displays, like on the ECHOMAP 74sv, use special coatings and backlighting to maintain visibility in bright conditions. Touchscreen versus keyed control is a personal preference, but remember that touchscreens can be less reliable in rain and spray.

Sonar Types Explained

Sonar technology has evolved significantly, and understanding the terminology helps you choose wisely. CHIRP sonar sends a continuous sweep of frequencies rather than a single frequency, producing clearer fish arches and better target separation. This is now standard on most quality fish finders, including every unit in our lineup.

Scanning sonar comes in several forms. ClearVu (Garmin) and DownScan (Simrad) produce near-photographic images of structure directly beneath your boat. SideVu (Garmin) and SideScan extend your view to the sides, covering much more water. Panoptix (Garmin) is live forward-looking sonar that shows real-time activity ahead of your boat. More sonar types mean more capability but also more complexity and higher investment.

Chart Compatibility and Subscription Costs

Chart compatibility is one of the most overlooked factors in boat GPS selection, and forum discussions on The Hull Truth consistently highlight subscription fatigue as a major pain point. Garmin uses LakeVu, BlueChart, and Navionics charts. Humminbird uses LakeMaster, CoastMaster, and Navionics. Simrad uses C-MAP. Each chart system has strengths and weaknesses, and switching brands means buying new chart cards.

Subscription costs deserve careful attention. Some charts include a year of updates and then require annual renewal fees. Navionics updates cost money after the first year. Garmin Quickdraw and Humminbird AutoChart Live let you build your own maps for free, which is a genuine cost-saving feature if you fish waters that are poorly charted. Factor in long-term chart costs when comparing units, not just the initial hardware investment.

Waterproof Rating and Build Quality

Marine electronics must withstand spray, rain, and occasional submersion. The IPX7 waterproof rating, found on units like the Garmin Striker 4, means the device can survive immersion in one meter of water for up to 30 minutes. Most quality marine GPS units meet or exceed this standard.

Build quality extends beyond waterproofing. Look for units with sturdy mounting systems, sealed connectors, and UV-resistant displays. The transducer is the component most exposed to the marine environment, so pay attention to the mounting type (transom mount, thru-hull, trolling motor mount) and make sure it is appropriate for your boat. Forum users on r/boating frequently report that poor transducer installation is the number-one cause of sonar performance issues.

Connectivity and Integration

Modern boat GPS units increasingly offer connectivity features. Wi-Fi lets you connect to mobile apps for software updates, chart downloads, and community sharing. NMEA 2000 networking allows integration with engine data, fuel sensors, autopilots, and other marine electronics. Bluetooth enables wireless remote controls and smartphone integration.

If you plan to build an integrated electronics package over time, choose a unit with strong networking capabilities. The Simrad GO9, Garmin ECHOMAP UHD2 74sv, and GPSMAP 943xsv all offer NMEA 2000 support. The Striker line has Wi-Fi but limited networking. Think about what you might want to add in the future before committing to a platform.

Installation Difficulty for Beginners

Installation complexity varies significantly between units. Compact fish finders like the Striker 4 can be installed in under an hour with basic tools. Larger chartplotters require more planning for power routing, transducer installation, and mounting. Thru-hull transducer installations require drilling a hole below the waterline and are best left to professionals.

If you are a DIY installer, look for units with transom-mount transducers, included mounting hardware, and clear documentation. Garmin units generally have excellent documentation and a large community of users sharing installation tips online. Humminbird and Simrad also provide solid installation guides. Consider whether you need professional installation when planning your marine GPS purchase.

Final Recommendations: Which Boat GPS Is Right for You?

After testing all eight units, our recommendations come down to what kind of boater you are. If you want the best overall experience with touchscreen navigation, pre-loaded charts, and triple sonar, the Garmin ECHOMAP UHD2 74sv is our Editor’s Choice and the unit we recommend to most serious boaters. Its perfect 4.9-star rating speaks for itself.

If you prioritize value and want the most capability per dollar, the Garmin Striker Vivid 7cv gives you a large vivid display, CHIRP and ClearVu sonar, and Quickdraw Contours mapping. For anglers on a budget or those with small boats, the Garmin Striker 4 remains the category-defining entry-level fish finder with nearly 10,000 reviews backing its reliability.

For boaters who want a tablet-like touchscreen experience with C-MAP charts, the Simrad GO9 is the strongest non-Garmin option. And for those building a professional-grade electronics package, the Garmin GPSMAP 943xsv with its IPS display, UHD sonar, and Panoptix support represents the height of current marine GPS technology. Whatever you choose, investing in the best boat GPS for your needs will make every trip safer and more productive in 2026.
