A friend of mine is big into geocaching and has an underwater cache.
He recently received this mail from somebody who accessed the cache.
Just to put you in the picture, they used a breeze block with rope attached to the end of a water bottle (float / buoy) as a line to mark the spot and dropped down on to the point for the search -seems sensible so far although I might have used something a bit more robust than a water bottle.
When they found the Geocache (which is under a concrete block) they decided to move the breeze block to that position, now read on .....
How to lift a breeze block and swim? I filled so much air into my jacket as I needed to lift the block. I did not want to drag the block over the sea bottom to not get sooooo much sand up. Reached smartgelb again, placed the block and now our trouble started - I have not been able to get the air out of my jacket. I did hold on your rope that did hold the slab and the blocks together and was floating feet up and have been unable to get my legs down. The jacket, I borrowed, had no emergency release on the lower end of the jacket, so the release openings have always been lower than the air bubble. To make a long story short: I decided to get rid of my jacket, including tank and regulator..... and made a controlled ascend with smartgelb using her 2nd regulator. The team on the boat had been a little shocked that the jacket came up without a diver!
I am surprised the jacket did not explode or was damaged in some way. the cache incidentally is around 12M deep
I assume that the "emergency release" is referring to the dump valve.
