Conventional Sonar

Listens to a single frequency

ClearPulse CHIRP Technology - How it works


Conventional sonar modules transmit and listen to at a single frequency with each pulse.

CHIRP transmissions allow more sonar power to penetrate the water – in fact x10 more power when compared to conventional sonar modules. ClearPulse CHIRP technology takes advantage of a wide spectrum of sonar signals to deliver amazing detail and accuracy.
