had seen a vague reference that the antenna cable from the coil did not have to come all the way up to the RC to get a signal. I don't dive but, may want to detect the edge of fresh water streams, ponds and lakes. What I came up with will allow submerging the coil about 20" inches or so. It can be left in place for ground hunting and does not prevent quickly collapsing or taking apart the rods.
So I bought a thin black RG174 coaxial cable to play with. I stripped the ends and used marine grade heat shrink to seal them back up. I made the length just long enough to extend past the end of the lower rod. Wire tied the lower end and just left the upper end loose in the lower rod. May replace the wire ties with slick thin velcro straps to make cleaning under the coil easier.
Short clip showing it working.
I will need to do some more testing but the initial results look promising.
