I ordered a transducer for my Garmin 498 on Flea Bay. When it arrived I opened the box and started to read the instructions. Instead of drilling a hole through the hull this transucer shoots a beam through the hull from inside the bilge. Has anyone used one of these? Are they any good. The instructions suggest that if your hull has wood or foam in it you have to drill 1/3 way through and then install it. What is my hull? 92 sundancer.
