In the years that have passed since my first fishfinder, fishing technology has evolved a lot. I still recall seeing the icons of fish on the viewing screen. I remember being a kid and thinking that there was a large fish right under the boat. Although it didn't help me very much, the sonar and depth imagery technology have improved so much that a fish finder can be a great tool to improve your skills. Additionally, we now have great access to geolocation technology (GPS), which is available at very affordable prices. To create a comprehensive picture of your fishing grounds, combine underwater imagery data with location data to create combo units.


The sun uses 83/200kHz frequencies. The optional XNT9 DB 74T transducer, which uses 50/83/200 kHz frequencies, increases depth capability to 3,000 feet. DualBeam Plus sonars can operate simultaneously using both frequencies to create images in splitscreen or blended displays. The sonar can cover a 60-degree cone at 83 kHz. The cone is narrow at 20 degrees. 200 kHz covers the same area.

GPS fishfinders equipped with sonar systems can be very helpful for fishing. This device can locate your spot of fishing in less than a second thanks to its built-in GPS. CHIRP's sonar technology (continuous inertial refer pulse) allows for you to observe fish habits and feed patterns in greater detail than traditional GPS. A GPS fish finder with a screen larger than 7 inches is an important accessory for any fisherman.

You can use the high frequency (200 kHz) to read large areas of shallow water and get intimate details of the bottom. The low frequency, usually 50 kHz, allows you to probe the depths easily.
