Looks Good SD, And Thank You Sir for letting me work on your machine.
Plus let me say, Thank You for the Weather updates on what's coming...I know to be ready when you say............Ok Guys and Gals get ready ONSHORE WIND ALERT FOR THIS WEEKEND
John if you notice I hunt with the detector submerged in the Bay, but like surf digger said I don't think for diving to the limit of 250 feet...I think you will be fine. Now the Skullies you have to baby them..dunks only....
Each handle is cut to fit the toggle in, the wiring to the toggle is sealed with an epoxy before putting in place, once in place the toggle is epoxied into position, then wrapped with silicon tape.
The remote used is a IP68 toggle along with a IP67 boot cover, the rear area were the connection is made is incased with 2 part heated epoxy, then I inject RTV silicon to finish up any airspace left. The toggle has 30,000 life cycles, The endcap I make has tighter tolerance's then the factory, Machined from a Acrylic rod, Not like the weak casting from the factory, And a larger O-ring for more surface seal area is used. On each machine I do, the endcap goes on, then the endcap is totally sealed with Aquaseal then before it dries I heat shrink the black shrink wrap, the two become one, Totally sealing this from any sand and water. I do think this setup will last the life of the machine above or below water.
