A GPS fishfinder is a tool that can be used by anglers to improve their chances of catching more fish. The device uses built-in sonar capabilities to provide views of the bottom of the body of water you are fishing on. There are a variety of GPS fishfinders on the market, so look closely at the features of several different models in order to choose the one that's right for you.
Instructions
1. Find a store that sells several different GPS fishfinder devices in order to be able to make comparisons between models. You can find them at most boating stores, outfitters, or marine electronics suppliers.
2. Look at the depth that each unit's sonar can reach. Some models like the Garmin Fishfinder 90 may have a maximum depth of 600 feet, while other models like the Hummingbird 777C2 GPS fishfinder can reach depths up to 1,500 feet.
3. Browse the display features of each fishfinder. Ideally, you'll want a model that displays fish in real time. There are also models that can give you actual fish returns as well as reveal close-hanging fish.
4. Compare pricing information for the GPS fishfinders. For recreational anglers, units like the Hummingbird Fishfinder 525 cost around $200 and are ideal for freshwater lakes. Commercial anglers will likely spend about $700 to $1,000 for a fishfinder like the Furono FCV620 with features like a triducer, rapid transmission rate and digital navigational data.
5. Read reviews online or in magazines before you choose your GPS fishfinder. Expert and user reviews can give you insight into how well the device worked for other users. You can use Galt (see References) as a starting point for fishfinder reviews.
