  14. Which GPS fish finder should you choose?

The best fish finder with GPS for most small-boat anglers is the Garmin Striker Vivid 4cv, because it combines a compact color display with waypoints, routes, boat-speed information and built-in contour mapping. For broad lake coverage, choose a Humminbird Helix 5; for a bigger display, consider a 7-inch Striker model.

GPS earns its place on a boat when it helps you repeat a useful trip. Mark a brush pile, dock, drop-off or other location, then return to it without relying on memory or a landmark that looks different in changing light.

Your needs may be simple: save a few waypoints and keep sonar in view. You may instead want built-in lake charts, maps you create as you travel, a larger screen, or chartplotter functions for inland or coastal water.

This roundup compares ten options by the GPS, mapping and sonar features stated for each model. For a broader look at how units differ, read types of fish finders and how to choose one.

Our boat-mounted fish finder guide covers installation and console choices.

Which fish finder with GPS is best for marking spots?

The Garmin Striker Vivid 4cv is the strongest all-around pick here for marking fishing spots because it combines waypoint and route tools with Quickdraw Contours mapping. Pick a different model if your main goal is a bigger screen, wider chart coverage or a simpler waypoint map.

The Garmin Striker 4 has a more basic approach: a keyed interface and waypoint map for marking and navigating to places such as brush piles, stumps and docks. It may suit you if you value straightforward controls and don't need the contour mapping features named on some other picks.

If a map should show more than saved points, compare the Garmin Quickdraw Contours units with the Humminbird Helix 5 models. The Helix 5 CHIRP GPS G3 includes Basemap coverage of 10,000+ lakes and continental U.S. coastlines, plus AutoChart Live recording for depth contours and other bottom details.

The two ECHOMAP UHD2 models take a chartplotter approach. One includes U.S. inland maps and the other U.S. coastal maps, so the right choice depends on where you fish.

How we chose these GPS fish finders

We compared the stated GPS tools, map features, screen sizes and sonar features against what anglers need when marking and revisiting spots.

Our score weighs specs and features against the needs of someone shopping for GPS-enabled fishing.

GPS features vary enough that the word “GPS” alone doesn't tell you what a unit can do. We favored products with clear information about waypoint marking, routes, speed display, chart coverage or map creation, then considered screen size and sonar as supporting features.

We also kept use cases distinct. A 3.5-inch unit may work well when a compact display is the priority, while a 7-inch model gives more viewing room but needs space at the console.

A chartplotter with inland or coastal maps suits a different buyer from a unit centered on saving waypoints.

The included details don't confirm every model's full GPS capability. Where waypoint or route functions are not stated, we don't assume them.

Garmin Striker 4: Best for simple waypoint marking

Garmin Striker 4, fish finders with GPS for marking fishing spots
9.1/10Our score
  • Built-in GPS waypoint map
  • CHIRP sonar
  • 3.5-inch display
  • Built-in flasher

A compact, button-operated unit for marking locations such as brush piles, stumps and docks. Its waypoint map keeps the focus on saved spots and return trips.

See it on Amazon

Pros

  • Waypoint map supports marking and navigation
  • Dedicated buttons
  • Built-in flasher for vertical jigging or ice fishing

Cons

  • Smallest display in this roundup
  • No built-in contour mapping feature stated

The Garmin Striker 4 is the straightforward choice if you mainly want to save a location and find it again. Its waypoint map lets you mark and navigate to locations such as brush piles, stumps and docks.

A keyed interface with dedicated buttons keeps the controls direct. The 3.5-inch display is the smallest in this group, so it leaves less room to read multiple kinds of information at once than the 5- and 7-inch choices.

CHIRP sonar sends a sweep of frequencies, and Garmin says it can create crisper fish arches with better target separation. ClearVü scanning sonar is also included, and the built-in flasher can suit vertical jigging or ice fishing.

This model's stated GPS feature is a waypoint map. It doesn't have a built-in contour mapping feature listed among its features, so choose a Quickdraw Contours or AutoChart Live option if drawing your own maps matters.

The Striker 4 fits anglers who want buttons, sonar and saved spots in a compact unit. If you've never owned a fish finder, compare its controls with the choices in our guide for first-time fish finder owners.

Garmin Striker Vivid 4cv: Best for compact mapping

Garmin Striker Vivid 4cv, fish finders with GPS for marking fishing spots
9.0/10Our score
  • High-sensitivity GPS
  • Quickdraw Contours mapping
  • 4-inch color display
  • CHIRP and ClearVü sonar

This compact color unit combines GPS waypoint and route tools with built-in contour mapping. It suits a small console where a bigger screen would crowd the controls.

See it on Amazon

Pros

  • Waypoint, route and speed functions
  • Built-in contour mapping
  • Includes GT20 transducer

Cons

  • 4-inch display limits viewing area
  • No Wi-Fi feature stated

The Garmin Striker Vivid 4cv is a compact color option with waypoint, route and mapping tools. High-sensitivity GPS supports marking waypoints, creating routes and viewing boat speed, while built-in Quickdraw Contours lets you create and save maps.

Its 4-inch display sits between the 3.5-inch Striker 4 and the 5-inch units. That size can be a practical fit for a small console, but a split view will have less room than on a larger display.

The included GT20 transducer supports Garmin CHIRP traditional sonar and CHIRP ClearVü scanning sonar. Vivid scanning sonar color palettes are designed to help distinguish fish and structure.

Choose this model if you want mapping features in a compact format and don't need a 7-inch screen. If you want to compare it with another Garmin compact unit, read our Striker Vivid 4cv vs Striker Plus 4 comparison.

What should you look for in a fish finder with GPS?

Choose GPS features based on how you plan to use saved locations. A waypoint tool supports saving and returning to spots; chart coverage and map creation add different kinds of navigation context.

Do you need waypoints, routes or charts?

A waypoint is a saved point, such as a brush pile or dock. Routes connect locations, while charts show mapped water areas.

Models like the Garmin Striker Vivid 4cv state waypoint, route and boat-speed functions; the ECHOMAP UHD2 models add inland or coastal maps.

The Garmin Striker 4 is a simpler option if waypoint marking is enough. A unit with charts may be a better fit if you want to see your location against coverage for a specific lake or coast.

Is map creation important?

Choose a fish finder with a named mapping feature if you want to record contours as you travel. Garmin Quickdraw Contours supports creating and saving maps on several Striker models, while Humminbird AutoChart Live records depth contours, bottom hardness and vegetation.

Map tools differ in how they work and how much recording capacity is built in. The Helix 5 models have eight hours of AutoChart Live recording, while several Striker models state Quickdraw Contours storage capacity of up to 2 million acres.

What screen size fits your boat?

A 3.5- or 4-inch display keeps the unit compact, while 5-inch screens give maps and sonar more room. A 7-inch display can make split views easier to see, but check your console space and mounting position first.

Screen size isn't a substitute for checking the controls and views you expect to use. If your boat is small, read our guide to fish finders for a 14-foot aluminum boat.

Which sonar features matter alongside GPS?

CHIRP traditional sonar appears across several models in this roundup, while some add ClearVü, Down Imaging or DownScan. These sonar features can help you read what is below or around the boat, but they serve a different purpose from GPS and charts.

If sonar terms are unfamiliar, our guide to fish finder types explains the differences. You can also compare Garmin and Humminbird fish finders to see how the brands approach screens, charts and controls.

Which GPS fish finder should you choose?

Choose the Garmin Striker Vivid 4cv if you want compact GPS tools and contour mapping, or the Humminbird Helix 5 CHIRP GPS G3 if lake coverage and AutoChart Live matter most. For larger screens, choose a 7-inch Striker; for built-in charts, match the ECHOMAP UHD2 map coverage to your fishing area.

If you only need to mark a few spots, the Garmin Striker 4 keeps the focus on waypoints and simple controls. If you need coastal charts, choose the ECHOMAP UHD2 54cv; for inland charts, compare the 53cv and Lowrance Eagle 5 SplitShot HD.

Before you buy, check the screen size against your console, then confirm that the model's stated GPS and map features match how you fish. For more options grouped by boat use, continue to our boat-mounted fish finder guide.

Frequently asked questions

What does GPS do on a fish finder?

GPS lets you mark locations and return to them later. Depending on the model, it can also support routes, show boat speed, display charts or help you create depth contour maps.

Check which of those functions matter to you, since a waypoint map and a chartplotter with preloaded maps serve different needs.

Can a fish finder with GPS make its own maps?

Some models can create maps as you boat. Garmin Quickdraw Contours and Humminbird AutoChart Live are examples in this roundup.

Other units focus on marking waypoints or using preloaded charts, so check for a named map-drawing feature if recording your own contours is a priority.

Do all GPS fish finders include lake charts?

No. Some units focus on GPS waypoints and routes, while chartplotter models may include preloaded coverage for inland or coastal waters.

Compare the stated map area with where you fish.

A chart label alone doesn't tell you whether your particular lake or shoreline is covered.

Is a 4-inch fish finder large enough?

A 4-inch screen can suit a compact console and basic waypoint use, but it leaves less room for maps and sonar views than a 5- or 7-inch display.

Think about viewing distance and whether you'll use split screens before choosing a size. Measure your mounting area, too.

What is the difference between a waypoint and a contour map?

A waypoint saves a location so you can return to a spot. A contour map shows depth changes across an area, which can help you understand the shape of a lake or the bottom around your route.

Some fish finders offer both tools, while simpler GPS units may focus on waypoints.
