Re: Choosing a depth sounder
As folks here have said, you can attach the transducer a number of ways. Toilet wax, Vaseline, epoxy. The only essential factor is no air bubbles in the medium - and you must have a solid (not cored) hull. If you have a cored hull it will not work. If you epoxy it in place, and trap air bubbles in the epoxy (through vigorous stirring), it will not work.
You may want to test for a good location beforehand; fill a plastic bag with water (remember, no air bubbles) and try it in a few spots, see where it works best.
If you want to go the fluid enclosure route, people generally use mineral oil. I went this way myself; I bought a piece of PVC piping from Home Depot, cut it to match the camber of the hull, and epoxied it into place. Filled it with mineral oil, put in the transducer (a moderately tight fit so it won't move), and screwed on the top. Done.
