Remember that some depth sounders may need some manual calibration ( refer to the manual). Do this in varying depths until you are confident that it is working. Mount the transducer and repeat to confirm calibration.
Ditto! The ziplock works like a charm.
You cant have any air between the puck and the hull. When I installed mine I thickened the epoxy slightly then used duct tape to hold it in place until it dried.
