I have a classic E with a DSM370 and need to select 12 deg thru hull xducer to provide max depth detection.
Thanks.
Welcome to the Raymarine Forum BocaIII,
Are you seeking a fairing block transducer
or a low profile transducer?
The A102112 B164 12 degree low profile transducer would be recommended for maximum depth performance in a CP370 compatible low profile tilted element thru-hull transducer for a hull having a deadrise of 8 to 15 degrees.
