I'll try to get a picture of a buddy of mine's set up the next time I'm out and he's fishing. He's got a Garmin echoMAP 73sv that he runs off the front, and his setup is pretty slick. It's not homemade, but one of the sponsors makes a unit called the da ducer but I can't remember who it is for the life of me at the moment. Maybe he'll chime in. It's a sweet looking setup
