I called and spoke to them today and sent them pictures of my jackplate and transducer mount on my 10" Bob's action jack. It's mounted on the holeshot plate. They told me they sell wedges that account for the angle you'll need for the transducer adjustment. I asked her how they know what angle my boat is at and how much I would have to adjust my transducer. She told me the guy that makes these knows this about most makes of boats. Thoughts?
