Fish Finders & GPS

Fish Finders & GPS to optimize your fishing trips

Fish finders & GPS units have become essential for locating fish, staying safe on the water and getting the most out of every session. Whether you fish lakes, rivers or saltwater, a good electronics combo helps you read bottom structure, follow your drifts and return precisely to your most productive spots.

On GiantFish.ch, you'll find easy-to-use fish finders for beginners as well as more advanced fish finder GPS combos, suitable for boat fishing, float tube fishing or kayak fishing.

How to choose the right fish finder

The right fish finder depends on your fishing style, average depth and the size of your boat or craft. The main criteria to consider are:

• Power and frequency for accurate readings in both shallow and deep water.
• CHIRP, Down Imaging or Side Imaging technology for better target separation and a more detailed view of the bottom.
• Screen size and resolution for comfortable viewing, even in bright sunlight.
• User interface and menus that make it easy to adjust sensitivity, zoom and color palettes.

For predator fishing, a responsive fish finder with excellent target separation is a real asset for tracking your lures and spotting schools of baitfish.

Using GPS effectively for fishing

GPS is not just there to show your position. Used correctly, it becomes a true electronic logbook. It lets you:

• Mark waypoints on drop-offs, rock piles, weed beds and productive wrecks.
• Plot routes to repeat a precise drift or trolling pass.
• Monitor your speed, which is especially useful for trolling or vertical fishing.

A fish finder & GPS combo brings all these functions together on a single screen, simplifying both reading and organization on board.

Installation, power supply and maintenance

Proper installation is key to getting accurate information from your fish finder & GPS. It is important to:

• Position the transducer in a clear area, away from bubbles and turbulence.
• Take care with the electrical supply by using cables of the correct gauge and clean, secure connections.
• Protect the display from shocks and moisture with a solid mount and, if possible, a protective cover.

After each trip, rinse your electronics with fresh water if you fish in saltwater, and regularly check the condition of the cables, mount and battery.

Techniques and seasonality with fish finders & GPS

A properly tuned fish finder helps you adapt your approach to the seasons. Early in the season and in spring, it helps you follow fish along shorelines and shallower areas. In summer, it becomes invaluable for finding cooler water layers and deeper structures. In autumn, it makes it easier to locate moving schools of baitfish.

For vertical fishing, jigging or slow winter techniques, accurate real-time display lets you position your lure exactly in the strike zone where the fish are holding.

Fish Finder & GPS FAQ

Which fish finder should I choose to start with?

An entry-level or mid-range model with a color screen, basic CHIRP and a transducer suited to the depths you fish is more than enough to learn how to read returns and understand bottom contours.

Fish finder & GPS combo or separate units?

For most anglers, a fish finder & GPS combo is the best compromise: a single screen, simpler installation and all the information in one place. Separate units can be useful on larger boats or for very specialized applications.
