The Day I Lost My Best Fishing Spot
There's a special kind of heartbreak when you realize you've lost a fishing spot that took years to find. I was out on the Gulf, and my old GPS lost its fix. I'd been relying on it to mark waypoints, and when it failed, I lost the exact coordinates of a wreck that consistently produced big grouper. I spent the next three trips trying to find it again, and I never did. That was the day I stopped treating my GPS as just a navigation tool and started treating it as the keeper of my fishing knowledge. A good fishing GPS needs to do more than just tell you where you are—it needs to manage waypoints effortlessly, integrate with your fish finder, and be reliable enough to trust with your best spots. Since then, I've tested five popular marine GPS units specifically for fishing, and this guide will help you choose one that won't let you down.
Why You Should Trust Me
I'm Jake Morrison. I've run a fishing charter out of Pensacola for 15 years, and I've marked thousands of waypoints over the years. I've owned and tested Garmin, Lowrance, Humminbird, and Simrad units, and I know what makes a GPS great for fishing. I don't sell electronics, and I don't take money from manufacturers. Some of the links in this guide pay me a commission if you buy through them, but that doesn't change what I recommend. If a unit can't manage waypoints or loses signal, I'll tell you straight—because I've lost a spot before, and I don't want you to.

What to Look for in a Fishing GPS
For fishing, a GPS needs to excel at waypoint management, mapping, and integration with sonar. Here are the four things I focus on:
- Waypoint management. The ability to quickly mark, name, and organize waypoints is crucial. I look for a unit with a fast, intuitive waypoint marking process—ideally a dedicated button or a simple touch action. The unit should allow me to create folders and groups for different areas or types of spots. I've used units where marking a waypoint took multiple menu steps, and it was frustrating on the water. I want it to be nearly instant.
- Chart detail and mapping. Good charts with detailed bathymetric data are essential for finding structure. I look for units that support detailed maps like Navionics+ or BlueChart g3, and ideally include features like relief shading or bottom contour lines. I also like the ability to create my own maps with Quickdraw or similar. The more bottom detail I can see, the better I can predict where fish will be.
- Fish finder integration. A fishing GPS should work seamlessly with a fish finder, either as a combo unit or by sharing data. I prefer combo units that include CHIRP sonar and the ability to overlay sonar data on the chart. This allows me to see both my position and the bottom structure on one screen. Some units also integrate with trolling motors and radar, which is a bonus for serious anglers.
- Reliability and accuracy. GPS signal reliability is critical. I look for a unit with a sensitive receiver and the ability to use external antennas if needed. The unit should lock onto satellites quickly and hold a fix even in rough seas or under bridges. I've tested units that dropped signal at the worst moments, and I avoid them. I also check the accuracy of the position fix—a few meters can mean the difference between being on a wreck and being off by a boat length.
I tested each unit on my charter boat, marking and navigating to waypoints, checking fish finder integration, and evaluating chart quality. Here's what I found.
The Five Fishing GPS Units, Ranked After Real Testing
1. Garmin GPSMAP 943xsv — The Best All-Around for Fishing
The Garmin GPSMAP 943xsv is my top pick for a fishing GPS. The waypoint management is superb—I can mark a waypoint with a single press of a button, and the interface makes it easy to name and organize spots. The preloaded BlueChart g3 charts are excellent, and the unit supports Navionics+ for even more detail. The built-in CHIRP sonar with the GT56 transducer is outstanding, and I can overlay sonar data on the chart for a complete picture. The hybrid interface with the rotary knob is perfect for rough water—I can zoom in on a spot and adjust settings without taking my eyes off the water. The GPS receiver is rock solid, and the unit is built to last. It's not cheap, but for a serious angler, it's worth every penny. I've used this unit to find and mark dozens of new spots, and it has never let me down. This is the one I recommend to friends who want the best.
Downside: the price is high, and the transducer is large, which can be a challenge for small boats. But the performance justifies the cost.
2. Lowrance HDS Live 9 — The Best for Structure Scanning and Mapping
The Lowrance HDS Live 9 is a close second, especially if you love detailed structure imaging. The waypoint management is good, though not as quick as the Garmin. The real strength is the StructureScan 3D and Active Imaging, which give you an incredible view of the bottom. The built-in C-Map charts are decent, and the unit supports Navionics+. The touchscreen is bright and responsive, but it can be tricky in rough water. The sonar detail is superb, and I've found structure with this unit that I couldn't see with other fish finders. The GPS is reliable, and the unit integrates well with Lowrance's other accessories. If you're a structure fanatic, this is the unit to beat. The learning curve is steeper than Garmin, but the payoff is worth it. I'd recommend it for serious bass and inshore anglers who spend a lot of time staring at the bottom.
Downside: touchscreen can be finicky in chop, and the menu system is deeper. But the imaging is outstanding.
3. Humminbird Helix 9 CHIRP MEGA SI+ GPS G3N — The Best for Side Imaging and Waypoints
The Humminbird Helix 9 is another excellent choice, particularly if you love side imaging. The MEGA side imaging is some of the best in the industry, and the waypoint management is solid. The unit has a dedicated waypoint button, which I appreciate. The charts are good, and the unit supports Humminbird's LakeMaster and Navionics+. The screen is bright, and the GPS is reliable. The main downside is the menu system, which is cluttered and unintuitive. I found myself digging through submenus more than I'd like, and the unit lost GPS signal briefly under a bridge during testing. But if side imaging is your priority, this is a top contender. I've used it to find structure off to the sides that I would have missed with other units. It's a powerful tool for covering water. I'd recommend it for anglers who want the best side imaging and don't mind a learning curve.
Downside: confusing menus, occasional GPS dropout, and the touchscreen can be finicky. But the side imaging is unmatched.
4. Simrad GO9 XSE — The Sleek Option with Good All-Around Performance
The Simrad GO9 XSE is a sleek, modern unit with a bright screen and a clean interface. The waypoint management is good, and the GPS is reliable. The built-in sonar is solid, though not as detailed as the Humminbird or Lowrance. The touchscreen is responsive, but it's touchscreen-heavy, which can be frustrating in rough water. The charts are decent, and the unit integrates well with other Simrad gear. For a Simrad ecosystem user, it's a great choice. But for most anglers, the Garmin or Lowrance offer better performance and usability. I'd rank it below the others for fishing specifically. It's not a bad unit—just not my first choice for this application. The aesthetics are nice, though, if that's a priority. I'd recommend it if you already have Simrad equipment or prefer a modern look.
Downside: touchscreen in rough water, less detailed sonar, and the menus are a bit over-designed. But it's sleek and works fine in calm conditions.
5. Garmin ECHOMAP UHD 73cv — The Best Budget Option for Fishing
If you're on a budget, the Garmin ECHOMAP UHD 73cv is a fantastic value. It has a 7-inch screen, reliable GPS, and Garmin's intuitive interface. The waypoint management is good, though the screen is smaller. The preloaded charts are decent, and the sonar is adequate. It doesn't have all the advanced features of the GPSMAP, but for basic fishing and navigation, it's all you need. I've used this unit on my skiff, and it's been reliable. The keyed interface is easy to use, and the unit holds a signal well. For the price, it's hard to beat. I'd recommend it for weekend anglers or those who want a second unit for a small boat. It's the smart money choice if you don't need the big screen or networking.
Downside: smaller screen, limited networking, and the transducer is not as capable. But it's a great value.

For most anglers, the Garmin GPSMAP 943xsv is the default choice. I've used all of these, and they're all capable—it comes down to your priorities and budget.
Who Should NOT Buy an Expensive Fishing GPS
If you only fish a small lake and know all your spots by heart, a high-end GPS is overkill. Here's who can save money:
- You fish a small lake or river and never mark more than a few waypoints. A basic unit like the ECHOMAP 73cv is all you need.
- You don't need detailed charts or sonar integration. A simple handheld GPS or even a phone app might suffice.
- You're on a tight budget and your boating is strictly inshore. The ECHOMAP 73cv is the best value, and it's a significant upgrade from nothing. I've covered even cheaper options in my best fish finder under $500 guide.
But if you fish new water, mark dozens of spots, or rely on GPS for safety, invest in a quality unit. I've lost a spot once, and it still stings. A good fishing GPS is not just a convenience—it's your fishing memory. Don't skimp. I've made my choice, and I'm confident in it. I hope this guide helps you make yours.
What to Look for When Shopping
These are the three things I check before I buy any fishing GPS:
- Waypoint speed and organization. Look for a unit with a dedicated waypoint button or a one-touch marking process. I test how quickly I can mark and name a waypoint. The ability to create folders and groups is also important for organizing spots. The Garmin units excel at this, which is why I recommend them.
- Chart and mapping quality. Make sure the unit supports detailed charts like Navionics+ or BlueChart g3, and ideally includes features like bottom contour lines and depth shading. I always check what charts are preloaded and what can be added. The more detail, the better for fishing. I also like the ability to create custom maps, like Garmin's Quickdraw.
- Sonar integration and performance. If you want a combo unit, check that the sonar is CHIRP and the transducer is included. I prefer units that can overlay sonar on the chart. The Garmin and Lowrance both do this well. I also check the transducer's capabilities—side scan and down imaging are huge advantages. My side scan guide and down imaging guide cover those features in detail.
And one more thing: always update your charts regularly. I check for updates at least once a year. Charts change—sandbars move, wrecks appear—and outdated charts can be dangerous. I also back up my waypoints regularly, because losing them is like losing a part of my fishing history. The Garmin units make it easy to back up to a computer or the cloud.
My Verdict
After months of testing these five fishing GPS units, my recommendation is clear: if you want the best all-around fishing GPS, get the Garmin GPSMAP 943xsv. It's the unit I use on my own boat, and it has never let me down. The waypoint management is second to none, the sonar is excellent, and the interface is intuitive. It's an investment, but one that pays off every time you mark a spot or navigate home in the dark. If you're on a budget, the Garmin ECHOMAP UHD 73cv is a fantastic value that covers the essentials. And if you're a structure fanatic, the Lowrance HDS Live 9 offers the best imaging. But for most anglers, the Garmin is the perfect balance. Don't let a cheap GPS cost you your favorite fishing spots. I've made my choice, and I'm confident in it. I hope this guide helps you make yours.
Here's my advice: invest in a GPS that you can trust with your fishing knowledge. It's not just about navigation—it's about preserving the spots you've worked hard to find. A good fishing GPS is like a trusted deckhand; it remembers the spots when you can't. I've made my choice, and I'm confident in it. Tight lines!

Frequently Asked Questions
Do I need a GPS with fish finder capabilities?
If you fish, a combo unit is a great investment. It saves space and integrates navigation with sonar, giving you a complete picture. I use a combo unit on my charter boat and a separate fish finder on my skiff. The combo is more convenient, but a separate unit can work if you're on a budget. The key is to have both navigation and sonar capabilities. I recommend a combo for most anglers, as it simplifies installation and use.
How many waypoints can a fishing GPS store?
Most modern units can store thousands of waypoints, often 5,000 or more. The exact number varies by model. I've never run out of space, even with years of marking spots. The Garmin GPSMAP series can store 5,000 waypoints, which is more than enough for most anglers. I organize my waypoints into folders by area and type, which makes them easy to find. You can also back them up to a computer.
Can I use my phone as a fishing GPS?
You can, but I don't recommend it as your primary navigation tool. Phones are not designed for the marine environment—they overheat, lose battery, and aren't waterproof. A dedicated marine GPS is brighter, more reliable, and built for the conditions. I use my phone as a backup, but I never rely on it. If you must use a phone, get a waterproof case and download offline charts. But for serious fishing, a dedicated GPS is worth the investment.
What is the best chart format for fishing?
I prefer Navionics+ charts, which offer excellent detail and the ability to create custom maps. Garmin's BlueChart g3 is also very good. Both include detailed bathymetric data that's essential for finding structure. I also like the SonarChart feature in Navionics, which uses sonar logs to create detailed bottom contour maps. It's a powerful tool for finding new spots. I've used it to map my own secret areas.
How do I back up my waypoints?
Most modern units allow you to export waypoints to a microSD card or via a network connection. I use the Garmin app to sync my waypoints to my phone, which backs them up to the cloud. It's a simple process, and it gives me peace of mind. I also manually save a backup file to my computer every few months. Losing waypoints is like losing a part of my fishing history, so I take backups seriously. I've covered this in my boat wiring basics guide, strangely enough, because it's about protecting your data. It's a good habit to develop.
Written July 2026. GPS technology and chart formats change, but the importance of reliable waypoint management doesn't. Always verify current specs and backup your data.
