              How To Choose The Best Fish Finders GPS Combo?

              There’re a few criteria you need to bear in mind when searching for the best fish finder GPS combo.

              Display

              • Three typical screen sizes are available, including 5, 7, and 9 inches. It's difficult to read the 5-inch screen, especially from a distance, but it's suitable for kayaks and small boats. Meantime, medium fishing boats require larger displays. The ideal resolution is at least 800 x 480 pixels.
              • If possible, seek extra features for enhanced visibility, such as glare-resistant or backlit screens. They allow you to get a good view even on sunny days; otherwise, flacking or cracking is unavoidable.

              Maximum Depth

              • Depending on your intended location for fishing, you should consider the suitable depth range of your device. A fish finder working effectively under thousands of feet of water may be too much for shallow water but never unnecessary for big lakes.
              • There's a variety of maximum depths you can choose from 500 feet up to 5000 feet. However, freshwater provides a better condition for fish finders' operation than saltwater in terms of depth.

              Transducer

              • It serves to detect signals reflected from objects after contacting beams in the water. Not all fish finders are equipped with transducers. Although they can still work by emitting their signals into the water, a transducer can provide stronger ones.
              • Don’t go for plastic units. They may be easy to install and inexpensive, but susceptible to breakdown. Instead, going for the stainless-steel model makes more sense.

              Navigation And Mapping

              • The higher the GPS frequencies are, the more accurate your device is. At the same time, excellent route plotting is feasible, even at high speeds.
              • Investment in good maps is worthwhile since you can quickly locate the boat and share your comments. Such data can appear on other devices like tablets, smartphones, in real-time thanks to the memory card and network connectivity.

              Waterproof

              • Water rating may be helpful in case you fear water may splash up into your boat and damage your fishfinder. The water rating of IPX6 or IPX7 is suitable. IPX7 implies the product can stay intact in water under a meter deep for half an hour, while the IPX6 label means resistance to the water jet for 3 minutes. If you drop the device into the water by mistake, it's still usable.

              Sonar

              • Low frequencies have a limited target separation ability but offer a broader range of sonars. Meanwhile, higher ones provide more detailed views and good separation despite restricted ranges.
              • In particular, CHIRP sonars adjust frequencies based on real conditions to create the best target detection and facilitate bottom mapping.

              Size

              • The size of your vehicle will decide how big the fish finder should be. Something compact is easy to fit into small boats, while smaller devices allow you to transport them around in a tackle box more conveniently. However, don't choose small finders, for it may be difficult to see data.

              Memory

              • Given the product integrates a fishfinder with GPS, it understandably consumes considerable space. Thus, make sure it has sufficient storage memory. Memory is available in a couple of forms: external or internal, but the combination of both works best.

              Which Brands Make The Best Fish Finders GPS Combo?

              Garmin

              • Garmin is a popular name worldwide among both amateur and professional fishers. It has launched several dependable products, notably fish finders for anglers, at a very affordable price range. Currently, the brand is leading GPS technology.

              Humminbird

              • Humminbird is proud of setting the trend with the latest technologies. It was the pioneer in equipping a waterproof depth sounder with LCR screens and then 360-degree sonar technology. The brand is committed to meeting customers' demands with its unique and innovative products.

              FAQs

              What are the advantages of a fish finder with a GPS?

              Compared to regular fish finders, those with a GPS reduce the time of location identification by half, allowing you to fish at great ease. They're easy to install, and you don't have to prepare tools besides a boat and power source. Their accuracy is undoubted, in terms of longitude and latitude.

              A GPS-equipped fish finder can work well in every weather conditions from rain, snow, ice to aggressive water bodies. Also, the unit enables the review of your boat's previous movements. At the same time, the internal database contains all necessary information for next fishing trips; thereby, there's no need to cram your mind.

              What maps are available for the GPS?

              Most fish finders document the map of large and well-known lakes. However, if your destination is streams or smaller ponds, you can customize and store your route in real-time as you start your journey.

              How do fish side imaging finders work?

              A side-imaging fish finder locates marine creatures by emitting sonar waves from boat sides. It provides an overview of water bodies and shows you to the hidden corners of bays where fish may gather. At the same time, the process of scanning the water is quicker since the device searches many directions at the same time.

              How long do fish finders last?

              The duration of fish finders depends on the capacity of the battery used. A 15 to 18Ah battery can power a 10-12-hour trip. Meanwhile, the 4.5-6 Ah model supplies enough energy for shorter trips that last for 3 to 4 hours.

              Can you see fish on down imaging?

              Yes. Down imaging acts by directing sonar waves from the bottom of your boat, thereby finding more fish.

              Is side imaging better than down imaging?

              It depends. Compared to down imaging, side imaging provides a better point of view with better picture quality in shallow creeks and bays. However, it only proves useful when capturing at low speeds, so you may miss several schools of fish. Down imaging can work well when the boat reaches high paces, and it suits deep waters.

              Conclusion

              Before seeking the best fish finder GPS combo for your own, it's crucial to research water type and the depth of fish you desire to catch.
