Yes - they are now called Drones. I remember Answering Machines before they became Voicemail and Self-portraits became Selfies. Maybe we should change from Caves to Underground Voids?  ;)

Isn't the idea that the new name is shorter than the old?  :shrug:

Got ideal place for underwater drone, was talking about it Sunday night after a site visit, although that drone there is a bit big, so maybe not ideal then! Cwm Cipwrth copper mine. Three flooded shafts, one a winding shaft down to 15 fathoms maybe, one possibly blind, the other possibly also down to winding level. No drainage adits (there is an adit, but it's separate working above shaft level), so nothing's been seen in there for probably 150 years. Was thinking more in terms of the Martin Zero approach of lowering a camera into shafts (railway tunnels in his case) from a fishing rod!

I am sure there used to be a deep adit, although it was completely flooded and I think well vegetated when i looked at it in 1971. Here is a photo of the waterwheel from that visit. The upper adit was accessible at that time.

AditNow leads the way! Here's our ROV  :)

First photo teething problems; a diver goes out to retrieve some parts that fell off!
Second photo; Paul models the intact ROV.
