[CA] [CA11] Sounder modules

Welcome to the Raymarine Forum egavasm,

Should there be a fault with the DSM300 such that it is not recognizing the transducer as a 1kW transducer, then power output will be limited to 600W and depth performance would be similar to that of a 600W transducer. One of the failure points of the DSM300 would be a failure to recognize that it was interfaced to a 1kW transducer. Some relatively significant improvements in sonar processing were also incorporated in the CP370 which improved its depth and sensitivity beyond the capabilities of the DSM300. Accordingly, it would indeed be worth considering replacement of the DSM300 with a CP370. Please additionally not that we have received anecdotal feedback from users specifying that the maximum depth performance of tilted element transducers is generally less than that of a transducer of similar design which is designed with an element which shoots straight downwards.
