The transducer is a large one, approximately 8" long and about 2" wide as it has side scanning ability. Mounting this to the bottom of the yak isn't an option as could be damaged by rocks and debris in the water or when loading the yak on a roof rack. Keep in mind, the older Wilderness System Ride's did not have a recessed area on the bottom of the yak to allow for a scupper mounted transducer. Mounting to the stern isn't an option as the size of the transducer would cause it to interfere with my rudder. And if I attempted to mount the transducer inside the yak and shoot through the hull, I lose the ability to side scanning -- kind of a key feature for this fish finder.
So, as I see it, I'm left with an over the side type of mount for the transducer --- unless you have an idea I've over looked. But that is were I get into the problem of what to do with all that extra transducer cable. I really don't want that flapping around on the deck.
