[CA] [CA11] Raymarine Axiom XL 16" Configuration/2kw Sonar

Fish On,

The recommendation for the 3kW over the 2kW transducer was not for power output, the CP570 is capped at 2kW. The additional elements within the 3kW transducer would make it more sensitive and therefore better able to acquire the maximum operational depth which you have specified. When operating in shallow water, fixed medium frequency would be recommended and you may find that the CP570/R509 LM 3KW CHIRP Transducer will hold bottom to as low as 3' of water depth beneath the transducer. Generally, most would switch over to using low power / high frequency CHIRP SONAR supported by the RVX1000 and RV transducers when operating in such very shallow water.
