 Topic: Depth FinderPosted: June-08-2004 at 2:29am |

I want to install a depth finder in my boat. Has anyone tried a "shoot-thru-hull" type transducer on a late '70's CC? I'd prefer not to hang the transducer on the transom nor drill my hull.

The one I'm looking at buying is not recommended for shooting thru a hull with more than 3/4" of wood. Are our boat hulls solid fiberglass? ...or do we have a layer of wood?
77stang, what depth sounder are you using? |

you are correct. cant shoot through wood (wood is too pourous) but you can shoot through glass. to work properly your transducer cant have any air between itself and the sea floor. your hull is full glass. to mount you will be making a bed of epoxy and setting the transducer in it to cure. make sure you bed of epoxy is large enough to cover the complete surface area of the transducer. we have an inexpenseive uniden. basically does exactly what i want. I got a pdf article comparing different brands. just dont know how to attach to my post

I have a Hummingbird 2 1/2" under dash mount. When I found the correct location, i left water in the bilge, and put a sandbag on top of the transducer, and cruised around the lake at different speeds. it took two tries to get it to read at high speeds.

Well, I've purchased the teleflex with the shoot-thru-hull transducer. I tried various methods of finding a good spot, none of which seemed to work very well. So I epoxied it down behind the transmission about 6" off center. I get good readings maybe one-third of the time. Is this normal due to irregularities in the bottom of the lake? Or did I just pick a bad spot for my transducer?
