Best Marine GPS Devices Without Fishfinder for Simple Navigation and Reliable Positioning
Yes—there are marine GPS devices designed primarily for navigation and waypoint management without built-in fishfinding features. This guide highlights five options, including two dedicated GPS handhelds and three chartplotters that pair GPS capability with sonar in some configurations. The best fits are listed with who they’re for, key trade-offs, and practical buying considerations.
Buying Guide Snapshot
- Best for rugged, water-ready handheld navigation: Garmin GPSMAP 79sc, Garmin GPSMAP 79s

| Product | Best For |
|---|---|
| Garmin GPSMAP 79sc | Rugged, floating handheld with BlueChart coastal charts for offshore navigation |
| Garmin GPSMAP 79s | Worldwide basemap, durable handheld for all-weather use |
| Garmin Striker 5CV | Budget freshwater/saltwater fishfinder with GPS basics; adds sonar |
| Humminbird Helix 5 G3 | Dual Spectrum CHIRP sonar with built-in basemap; advanced navigation features |
| Garmin ECHOMAP UHD2 53CV | Chartplotter with fishfinder capabilities and Inland maps; broader display |
Garmin GPSMAP 79sc Marine Handheld
Best for serious mariners who need a rugged, floatable device with extensive waypoint storage and coastal chart coverage. The 79sc supports multiple satellite constellations for reliable tracking worldwide, plus built-in compass and increased memory to store up to 10,000 waypoints and 250 routes. This is a purpose-built GPS handheld, optimized for navigation rather than sonar.
Who it’s for: offshore sailors, coastal cruisers, and kayakers who value durability, floatation, and long-term waypoint/nav routing capability over fishfinding features. Caution: No dedicated built-in sonar; relies on charts for navigation data, not fish targets.
Garmin GPSMAP 79s Marine Handheld
Best for mariners needing a worldwide basemap in a rugged, floating form factor. The 79s echoes the 79sc with similar ruggedness and memory for vast waypoint and route storage. It provides reliable navigation, waypoint management, and multi-constellation tracking, ideal for explorers who want a capable backup or primary GPS device without sonar.
Who it’s for: coastal travelers, boat owners seeking a durable non-sonar GPS with broad basemap coverage. Limitation: As a navigation-focused device, it does not replace a chartplotter with integrated sonar on larger vessels.
Garmin Striker 5CV
Best for budget-friendly setups where a simple GPS navigation system is paired with a built-in sonar option. The Striker 5CV includes a transducer for CHIRP traditional sonar and ClearVü scanning sonar, but can be relied on primarily for GPS navigation and waypoint tracking when sonar is not needed.
Who it’s for: anglers who want an all-in-one unit but prefer to use GPS navigation without relying on fishfinding data, or those who plan to add sonar later. Caution: Sonar features may tempt users to rely on fish targets; the GPS navigation performance is the focus when sonar is minimized.
Humminbird Helix 5 G3 GPS
Best for versatile screen navigation with robust mapping and dual-channel sonar options. While it includes fishfinding capabilities, the GPS and basemap features support reliable navigation, waypoint management, and chart plotting across inland and coastal waters.
Who it’s for: boaters who want a flexible navigation device with sonar as an option, and those who expect to integrate premium charts. Limitation: If the goal is strictly GPS-only, the sonar features may tempt usage, and price can be higher than pure GPS handhelds.
Garmin ECHOMAP UHD2 53CV
Best for chartplotting with enhanced sonar views. The UHD2 model provides a 5” color display, CHIRP traditional and ClearVü sonar, and inland mapping. It’s ideal for those who want a compact chartplotter with optional sonar capabilities for a broader navigation and fishing workflow.
Who it’s for: small craft operators who want a compact chartplotter with the option to view sonar data when needed. Caution: It is not purely GPS-focused; sonar features are a core part of the system, which may be unnecessary for buyers strictly seeking GPS navigation.
Buying Guide: Key Purchase Considerations
- Navigation focus vs. sonar features: If your priority is GPS navigation and waypoint management, prefer dedicated handheld models (e.g., Garmin GPSMAP 79sc, 79s). If you want both navigation and fishfinding, consider chartplotters with sonar (Striker, Humminbird Helix, ECHOMAP UHD2).
- Durability and water exposure: Look for IP ratings and flotation features for handheld devices intended for open water or rough conditions.
- Display size and readability: Smaller screens are adequate for GPS navigation, but larger displays improve map readability and route planning in daylight outdoors.
- Memory and mapping coverage: Ensure enough waypoint storage and that the device includes or supports the coastal, inland, or basemap data you need.
- Future expandability: Some devices support additional maps, charts, or sonar modules; plan for future upgrades if you anticipate expanding capabilities.
Frequently Asked Questions
- What is the main difference between a marine GPS handheld and a fishfinder?
– A marine GPS handheld focuses on navigation, waypoints, routes, and position tracking. A fishfinder adds sonar to locate fish and underwater structures. - Can a GPS-only device still be used on a boat with charts?
– Yes. GPS-only devices use charts to navigate, mark waypoints, and plot courses without sonar. - Are there rugged handheld options that float?
– Yes. Several Garmin handhelds are rugged and designed to float, making them safer for water use. - Is it possible to upgrade a GPS with additional charts later?
– Many devices support map upgrades or external chart packages; check compatibility with your model. - Do chartplotters with sonar offer navigation benefits without using sonar?
– They do offer GPS-based navigation, but sonar features may be underutilized if you prefer navigation-only use. - Which device is best for strict GPS navigation on a budget?
– A dedicated GPS handheld like the Garmin GPSMAP 79sc or 79s usually provides strong navigation with less cost and complexity than combined chartplotters.
