A GPS fish finder can make locating fish ten times easier. If you have never used one before, you should buy one now. Once you use it on your fishing trip, you’ll never want to go without it. We recommend you buy a fish finder for sport fishing, bass fishing, and exploring the lake. If you don’t have a GPS fish finder, you need to add it to your fishing gear.
How Does a GPS Fish Finder Work?
A GPS fish finder uses underwater sounds such as sound and sonar waves to local objectives such as a fish or a useless tire. They send sound pulses into the water using active sonar while waiting for an echo. The echo informs the GPS fishfinder about the type of sounds that bounced off it.
How Does a GPS Fish Finder Work and Its Benefits?
GPS stands for Global Positioning System that locates signals going at the speed of light. The GPS calculates the distance each satellite is located. The benefits you receive with a GPS fish finder include:
- Tells you the location where you’ll find several fish.
- Locates different news areas in the water where you’ll find fish.
- Sends you notifications about the weather conditions.
- It synchronizes with your devices such as phone, tablet, or any handheld device.
- It eliminates the need to carry more than one device.
- Ensures you find a safe harbor during inclement weather conditions.
If you’re searching for a GPS fish finder, you’ll find several. Therefore, you need to know what features to look for in one to make the right decision.
Features of Fish Finder GPS
Here’s what to look for in a fish finder GPS:
There are two types of sonars — color and dual-channel CHIRP. Color sonars allow you to see what’s under your watercraft. The color helps you identify the object and show the differences between soft and hard surfaces.
Dual-channel CHIRP sonars produce longer pulses transmitting several different frequencies and provides you with more information.
The two types of frequencies are single frequency transponders and dual-frequency transponders. Single-frequency transponders use 200KHZ in freshwater lakes below 200 feet in depth. It exhibits schools of fish and single fish, including grasses, rocks, and other forms of vegetation.
A dual-frequency transponder combines a 50KHZ or wide beam with 200KHZ. You can use them in saltwater and deep lakes. If you fish in several different types of locations with varying depths, use this frequency transponder.
3. Depth Gauge and Temperature
Discover air and water temperature to find the perfect fishing spot. Use the temperature to determine the type of fish you’ll find in that area. Use a depth gauge to determine the depth of the water.
4. Automated Route Planning
Automated route planning tells you how long it’ll take you to reach your fishing spot.
Chartplotter provides you with a map and is a good feature if you visit other lakes other than your own local lake.
Other features you need to look for are smartphone integration, alert system, touch or large screen or both, a fixed or portable mount, and a transducer, which sends sound waves to determine what under the lake.
