[CA] [CA11] i50 with old tranducer

Larry,

Raymarine's instrument have not been designed and tested for use with Datamarine transducers. The reported issue may be resulting from an incompatible transducer, failing transducer, or less likely, with the depth instrument itself. One may verify whether this is the case by interfacing the instrument to a compatible Raymarine instrument transducer which is suspended over the side of the hull in water permitting the transducer to be suspended at least 3' above the bottom. Should the depth instrument correctly report depth, then the Datamarine transducer should be replaced with a compatible Raymarine instrument transducer.
