What is a fishfinder? Why is it useful for bait boats?

Fishfinders are such instruments that omit ultrasounds towards the river bed in the water which reflecting back from the river bed senses if there are fishes nearby. It defines the water depth, the size, quantity of the fishes and their position relative to the water surface. In case of bait boats, a sonar is installed to the bottom of the boats of which transmitters transits the signals to the shore and the Coast unit receives the signals and shows them on the screen. So it’s not questionable why this gadget is so useful for anglers, because it makes the discovering of the water significantly easier, thus we can define more accurately where we should drop the baits and fish.
