Transducer placement

[Nickvan]

I'm at the 7 ft rooster tail stage with mine... I epoxied mine on because I'm not going to drill holes below the waterline for anything nearly as esoteric as a first position on a finder. I really like the cutting board idea, though. I put some water in the boat last time out and tried to get a reading through the aluminum. Depth was about right (checked with paddle), but no contour. I don't know if I should go up or down next. Will post.
