Portable Sonar LCD Fish Finder, Alarm 100M AP, fishing iure, ice fishing finder

How it works?

Sonar technology is based on sound waves. The system uses sonar to locate 

and define structure, bottom contour and composition, as well depth directly

below the transducer. The transducer sends a sound wave signal and determines 

distance by measuring the time between the transmission of the sound wave and 

when the sound wave is reflected off an object; it then uses the reflected signal to 

interpret location, size, and composition of an object.
