| Why not use a small cell like the K1D? They are about half the size of the R22D but still output 10.5mV in air. Not much different in price. I think that's what Gordon put in the travel KISS.
For good cable glands try Rapid Electronics, I got some from them which are rated to 150m. Only about £1 each. If you f**k it up, Plumber's epoxy is good for sealing the hole up, I did this on my Ray scrubber. |
