Hi, I'm considering Raymarine i50 echo sounder with sensor, item no 15205. In the description and even delivery contents there is no indication about sensor. So my question is : which type sensor is (thru hull or not ) and in case thru what is the boring diameter for the sleeve? thank you in advance
Dear customer, the P319 Depth Thru-Hull Transducer is included. Hole diameter for installation: 2 inch. Thanks.
Raymarine part number E70148 includes a thru-hull transducer M78713-PZ. This requires a 51mm diameter mounting hole.
