And still cover it with warranty of course.
There you go. Problem solved.
It may just be me, but I figure if you want a shoot through the hull transducer, it's best to buy a shoot through the hull transducer. If you want a transom mount transducer, it's best to buy a transom mount transducer.
Gluing a transom mount transducer inside the hull may
work, but it's not the best plan.
Oh, and unless the hull is parallel with the surface of the water, it's going to be shooting at an angle and won't give an accurate reading if it gives one at all. The P79 that's designed to shoot through the hull is adjustable for different angles so it can be pointed directly at the bottom.
