An upside is that anyone unfaimilar with the cave can follow the wire right to the patient like a trail of bread crumbs. In my very limited experience, that's a more useful feature than the actual communication it (theoretically) delivers.

Many mines still use really, really old communications equipment and techniques.
The Alberta Speleological Society developed a cave radio in 1980 which, along with improvements, was sold to whomever wanted a pair (several in the USA, I believe). Ian Drummond was the designer/producer, but he now lives in Ontario and I'm not sure he makes them anymore. I can ask him if he'd give you the plans to make one yourself, if you're interested.pebblepoint wrote:Has anyone produced a reasonably priced, tough, commercially available cave radio that a semi-intelligent person can use?
