I just got a reply from garmin apparently you can plug one of these intelliducer's straight into your gpsmap and it will give you depth warnings. https://buy.garmin.com/shop/shop.do?cID=288&pID=26514#productTab however for the price you might aswell buy a half decent fishfinder, its just that the less wires the better and the AI is lacking the mounting area that some of the other Hobies have.


Might be able to mount this inside the hull and shoot straight down. Need to use some goop to stick it down and prevent it shooting through air before going through the hull.

What about the airspace in the hull?

The sound waves don't like travelling from one medium to another. Idealy they get hung over the back of your boat and covered in water. If you place the transducer inside your hull and press it against the bottom there is still an air gap which will upset the transmission of the sound wave.

To overcome this the transducer can be stuck down with "goop" such as "Marine Goop" or "Selleys All Clear". Some people also build a small "dam" out of foam and fill it with water. The idea is to exclude air and make the transmission path look more like water.

More info can be found on the kayak fishing forums or here-
