Transducer RV 220 pair

[Chuck - Raymarine - Moderator]

ReelAttitudeBDA,

The RV220 pair will support four types of sonar, DownVision, SideVision, RealVision 3Dâ„¢, and High CHIRP (conical) Sonar. The previously referenced provided approximate maximum operational depths for each of these types of sonar. When seeking to operate in depths greater than 600', it would be recommended that the High CHIRP (conical) Sonar channel be selected. Please see the screen snapshot below of an Axiom MFD equipped with RV220 pair in very deep water. Please additionally note that as the strength of reflected sonar signal diminishes with depth, the MFD may show a faint image of the bottom as shown below, but not populate the Depth data item due to inability to distinguish the return as bottom vs organics suspended within the water column.



For operation in depths greater than 900', would be recommended that the Axiomn MFD be fitted with a Y-Cable to which a compatible 50kHz/200kHz transducer may be connected. Alternatively, the Axiom MFD be interfaced to a CP370 w/compatible 1kW transducer or CP470/CP570 w/compatible CHIRP transducer.
