[CA] New System

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Eric,

Q1. The boat is a 1999 Sea Ray 370 express. Here is what I am considering:
2 - Axiom 12 displays
1 - Evo - T70154 - ECU 100 - Autopilot
1 - Quantum Q24C 18” Radar

A1. Before getting into the fishfinding features, it may be that you have selected an under-sized autopilot. What is the cubic capacity of the vessel's steering ram?

Q2. Please click here to view a FAQ addressing the maximum operational depth of RealVision 3D and DownVision. While both DownVision and the B60 with a DSM300 may have been a bit over matched for a lake having a maximum depth of a little over 900', I believe that the CP570 may be overkill for this application. Similarly, RealVision 3D is designed to support use in depths up to 300'. While supporting the depth range for for much salmon fishing in these waters, the strength of RealVision 3D and DownVision is in finding and identifying bottom structure. Accordingly would favor to the CP470 with a CHIRP transducer pair.
