Key Features

  • Patented ClearPulse digital sonar technology.
  • Sharper, well defined echoes.
  • Cleaner, noise-free display with enhanced inter-ping processing and comparison data.
  • Better shallow water, bottom tracking and thermocline recognition thanks to improved signal to noise ratios, reverb and interference rejection.
  • Surpasses conventional sonar with accurate performance from 2 to 10,000ft (dependent on transducer used).
 

 

 

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.
