[CA] deep water and cp200

[Chuck - Raymarine - Moderator]

Welcome back to the Raymarine Forum Sallysea,

Unlike other sounder technologies, SideVision technology is neither designed to report bottom depth nor autoranging. As such, it may indeed be used to scan the upper portion of the water column as long as you understand its limitations. Specifically, the fore/aft cone angle must be considered. The cone angle of each of the CPT-200 transducer's elements is approximately 60 degrees in the side to side axis and 1.4 degrees in the fore/aft axis. Given the narrow fore/aft angle, the CP200 will be most effective in identifying objects and structures when the vessel is moving forward or drifting rather than anchored.
