M_Boats: Depth/Fish Finder For M15

Hello all! I would like to know if anyone with an M15 has ever used a Depth/Fish Finder on their boat. I am leaning to the Fishin' Buddy 2255 by Bottom Line because it is removable. I don't want to drill a hole in the Hull. Anyone can email off line it they would like. I also would like to hear more sailing adventure stories too if you have them. I don't have too many myself yet! Thanks, Peter Peanut M15 618 "Its better to have feet then no shoes" It's raining here quite heavy!
