[CA] Transducer selection

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Ashley,

The first group of sonar channel options (groups separated by blue line) which you have listed
- RealVision 3D
- SideVision
- DownVision
- Sonar
- Chirp Low
- Chirp High
are all associated with the RV100 transducer. Please note that the LightHouse v3.2.x software erroneously lists Sonar and CHIRP Low within this group. In a nutshell, the RV transducers support RealVision 3D, SideVision, DownVision, and CHIRP High sonar.

The bottom grouping of sonar channels prefixed with CW are all associated with the TM275LH-W. The CHIRP Auto option within this grouping will automatically select between CW-H and CW-L. As indicated above, the LightHouse v3.2.x software erroneously lists other options. This error will be corrected within a future LightHouse 3 software update.
