The fishfinder shows you a profile of the sea floor on a colour screen. The fish finder works according to the principle of sonar, used in shipping for electro-acoustic measurement of water depth (sounding). Fishfinder multi-beam systems can be used to measure river beds, estuaries and shallow coasts and these devices are increasingly being used on yachts and by anglers and fishers as so-called fishfinder. The system can be used to distinguish soil, vegetation and fish, whereby the fishfinder echoes from fish are especially emphasised.
Many different fishfinder in various price categories can be found in the boatoon.com online-shop.
