Real-time fish finders

Real time fish display

— this function ensures that the fish is displayed on the sonar screen (see "Type") only as long as it is under the beam of the device — the signal disappears when it goes out of the beam. Thanks to this, the fisherman can track the situation in the water as accurately as possible, which is useful both in assessing the overall prospects of the chosen place, and in some types of fishing, when you need to cast the bait as close to the prey as possible.
