    British device? Heck your going back last century with this one but OK it narrows the field,
    I have vague memory of North West Watersports or Septre Watersports in Lincoln going back to the 60's/ 70's
    Too long ago to care. Bouyco pack is another contender for this junk.

    Draeger did some work on what was called a self rescue device for the SMS100 and SMS2000 projects also know as the "Wardrobe on your back" design similar in design for holding depth mid water but for when you stopped breathing it raised you to the surface a corrected rate up through the water column slowing you down at the 10mtr mark. Like raising the Mary Rose only in yellow for those recreational divers among us.

    The technical term was known as submarine egress in a water column depth. Without the incumbent blasting out the tubes like a cork, or sinking into the abyss.

    There's one of these boxes at Stoney so if anyone is going there, could they have a look at it and find out the name - it's bugging me trying to remember it!

    I did a bit of searching and it might be this, a Dacor Nautilus. Solid buoyancy chambers that are partially flooded with water and have an auto-dump to maintain a steady buoyancy.

    EDIT: rereading your post, missed the ref to the Dacor Nautilus first time round.

    Thanks Iain, that's the device I was looking for. It sunk without a trace - if you will pardon the pun.

    300 bar cylinder you deliberately pump sea water into.
    Electric pump to sort your buoyancy out.

    What could possibly go wrong.

    If God had meant us to breathe underwater, he would have given us larger bank balances.
    Human beings were invented by water as a means of moving itself from one place to another.

    And if it does go wrong it will prove impossible to access...
