Robert Laird asks:
"Darkness Beckons" ... Molephone ... what is it ....



This may be somewhat innacurate:

The Molephone is a device used mainly for cave to surface links. 
It is electromagnetic, and gets through rock using large coils 
as antennae. It is generally used for dry work, because of its 
size. It can be used underwater, the filmed Keald(?) head dive 
used one. They cost somewhere in the region of 3 grand(?) and 
are available from: 

					Lancaster University centre for technology transfer. 

I'm not sure it would be good for wrecks, as it was designed to 
transmit through limestone, not metal hulls+seawater, which 
presents a different set of problems for transmission.
I have tried to get info from Lancaster, but they haven't replied 
as yet. If anyone knows more I'd be keen to hear myself.

Derek.
