Hello everyone,
Our company is involved in raise boring (vertical tunnel boring). I have heard about a piece of equipment called the "Mole Phone" that cavers use.
Does anyone have any details about it? Who makes it? Etc. It would greatly assist our underground operations if it was suitable.
Many thanks,
JT.
