Adding second depth sounder to C125 MFD

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Pete,

The ax5/cx5/e7/ex5/eSx5 MFDs do not have internal fishfinder circuitry. However, such features may be added to these MFDs by interfacing them to one or more of the following:

------ 600W ClearPulse 50/200kHz Fishfinder Sounder features: ax7/cx7/e7D/ex7/eSx7 MFD (or retired DSM30) w/compatible transducer

------ 1kW ClearPulse 50/200kHz Fishfinder Sounder features: CP370 (or retired CP300 or DSM300) w/compatible transducer

------ 600' CHIRP/DownVision Fishfinder Sounder Features: ax8/eSx8 MFD or CP100 w/compatible transducer

------ SideVision Fishfinder Sounder Features: CP200 w/CPT-200 transducer

------ High Power CHIRP: CP470 or CP570 w/compatible transducer(s)

When operating with the latest a/c/e/eS/gS-Series MFD software, the depth reported within the Fishfinder application pages/panes will always graphically report depth sensed by the fishfinder transducer which is supporting the fishfinder application page/pane. The Depth data item of Raymarine MFDs will be populated using the Depth source specified within the MFD's Data Sources feature.

When selecting fishfinder sounder module for use with an ax5/cx5/e7/ex5/eSx5 MFD, it will be necessary have some additional information to provide assistance:
- how deep do you intend to fish
- how serious are you about fishing (casual, moderate, fishing is your life)
- type of hull ... already stated catamaran ... need to know whether it is a power or sail catamaran
- type of propulsion
- hull material
- thickness of the hull in the desired transducer mounting location
- whether core material was used in the hull's construction
