Those amazing features that helps anglers maximize every iota of time spent on the water are incorporated in this fishfinder. This fishfinder makes use of compressed High-intensity radiated pulse (CHIRP) tech. This technology is similar to the sonar and radar tech that the military has adopted for several years.

CHIRP is effective for fishing and this is because it can process and display two-dimensional sonar in a very detailed and accurate way even better than standard sonar. This is due to the fact that CHIRP operates at diverse frequencies. Since no two objects reflect the same frequency, CHIRP tech offers the best display of different objects, fish, including the structures beneath your boat.

CHIRP technology is also much better because it gives you the opportunity to view not just the sizes of the fish underneath, but your bait and the reaction of the fishes to the baits you use. This technology is effective for a range of 1,000 feet. It also uses Hybrid Dual Imaging (HDI). The HDI merges two of Lowrance’s previous tech, which are the Broadband Sounder and the DownScan imaging. The Broadband sounder has the ability to indicate small fishes better. On the other hand, the DownScan imaging can provide a detailed picture-like view of the lake base and its structure. For a depth of around 3,000 feet, the DownScan is ideal.

This unique fishfinder also boast of several thrilling technological features like the DownScan overlay and the TrackBack. With the DownScan overlay, you can easily differentiate a fish from a structure. However, with the TrackBack feature, you can retrace your path by simply looking at your sonar history.
