During the evenings of our full cave training courseโ€™s in france we inevitably end up over dinner ( cooked by our resident chef ๐Ÿ˜Ž ) discussing Technical Diving History. The people, the places, the technology and the operating procedures of the day ! Always an eye opener for modern divers.
I mentioned one night I had found something in a long lost box from back in the day.

So Tuesday Diving Trivia question ! What is this 1990s state of the art thing ! Bolt snap for scale.
Correct answer wins a used snoopy loop, not one of those posh ones with your name on either !

CDG members pre 2000, let everyone have a go first as you all have enough snoopy loops.
