[CA] [CA11] No option to chose CHIRP

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Believer,

Within the LightHouse 3 and LightHouse II Fishfinder application, the Sonar channel is the title give to the imaging which is produced from the low power / high frequency CHIRP transducer element of a RealVision, DownVision, or CPT-S transducer. The other CHIRP options which you have referenced are associated with compatible 1kW CHIRP transducers which have been interfaced to the 1kW Transducer socket of an Axiom Pro RVX MFD or RVX1000 3D CHIRP Sounder Module.
