Elliptical-shaped telesonar for locating fish, has magnetic switch slightly protruded in flat bottom part of buoy body, power source battery located in buoy body, and negative terminals arranged in fastening systems of battery
The telesonar has electronic cards transmitting information to a CPU (7) through transducers (14, 15). The transducers are arranged on lateral ribs (18, 19) and emitting electrical pulses and sending the information to the CPU through sound circuit boards (8, 10-12). A speaker (16) is also located on the ribs and is placed below a semi-major axis of a platform. A magnetic switch (6) slightly protrudes from the flat bottom part of the buoy body. A power source battery (17) is located in the buoy body and its negative terminals (20-23) are used as a fastening system to hold the battery.
