Raymarine's ClearPulse CHIRP Technology

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).

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.
