In winter or summer, the sonar or fish finder is a sophisticated tool that will help you locate the zones in which fish can be found, as well as analyze the seabed. You can also save your favourite spots to be able to come back to them later.
Various technologies are offered in order to suit your needs. Select a sonar based on the waterbody you intend to find on, and the frequency of your outings. One thing's for sure: your fishing stories will never be the same again!
