Transducer Options

Up to 30% loss signal loss on transmit and receive. Not a real problem in shallow water up to 150, but definately a problem in deeper water with units under 1000 watts. I once had it both ways on a Paramount superfish and ran a 200/50 glued inside. I did'nt know what I was missing until I transom mounted it. The biggest return issue when it was glued inside was the deminished fish show return.

Still rigging my 23 CC and about ready to install a pair of Garmin GT51M-THP transducers. My concern is the best hull location. They seem really large for a 23' boat . I like the second step location but my concern is will this location effect the water flow to the prop with a single outboard mounted on a twin Hermco bracket?

If you mount outside the first step, the water will be aerated, no bueno.
