My boat has a Raymarine B117 installed. My depth has been flakey in operation with both a DSM300 and my current E127. This tends to occur in shallow water the most and my suspicion is that this is the wrong transducer.
The B117 is mounted next to the speed transducer under the vberth drawers and can support a 0-7 degree deadrise.
I am curious to know what others have installed in this location as its bottom job time and I'm going to replace it.
