Pretty cool, Ive not seen a issued one before.
Ive a few others.

Seems odd that it “only” goes to 12 meters.
Needing another for deeper dives.
Whereas, “ what measures a lot, measures a little”
I can take a guess what this is for.
One of my sister-in-law's ex BFs was in the SBS, and he had a whole camp in Gibraltar where they did 5 km or longer insertion swims every day for training.
They used closed circuit re-breather aparatus, so there were no bubbles.
They were essentially shoved off a boat (or helicopter) a distance offshore and left as a squad to swim to target.
Not allowed on the surface, no bubbles from the set, the idea was to pop up at target, on time, with no warning whatsoever.
Total surprise.
The main thing was that they had to maintain 5-6m depth all the time.
If they went down to 10m, they ran out of oxygen (uses a third more than you do at 5m), if they went up to 2m, they could be seen by lookouts.
I can see no other use for a depth gauge that is limited to 12m, other than one where the use of the set is also limited.
All clearance stuff is likely to exceed this depth, and the depth is decided on what is being worked upoon. But with a shallow re-breather insertion swim the depth is dictated by the requirements of the set and the tactic, and is exactly in this range.
If you look online, there are ranges of military re-breather sets that are specifically designed for 0-10m depth use.

I've had a Google, but not turned up much regarding when the British military adopted the metric system - any ideas?
Very many thanks for that Dave.
I love this place...
Every day is a school day.
Or maybe one of these.

I read up about this model, and it was apparently issued to US marines recovery teams. This one has some letters written on the part of the band inside the housing.
Nice one.
Anybody got any ideas why the bezel
on that compass would be reversed??
Late night brainwave...
southern hemisphere?
Breathing pure o2 on a rebreather, the max operating depth is 25ft / 7m (from memory).
I don't know, anyone got a clue?Quote:
