Man, 190 ft which is 6 bar of pressure. I don't worry about the watch anymore but how can you survive under that high pressure. I don't know much of diving in that deep but do you wear the helmet. But I think this is not a normal diving. It is your special job work under water.
just another hobby.
no helmet, it's what we call tech diving.
you can do a search on google and check some "diving physics and the human body", way to much involved to start discussing it on a rep watch forum :lol:
to make it short (in a non divers language), you equalize your body to the surrounding pressure on your way down by holding your nose closed and press air into your nose and or chewing etc. .
on your way up, you give your body time to release the pressure (decompress). you could go down to 200fsw in 4 min, but then you could need 20 min to come back up.
everybody's body is different and it is very personal, many deco divers use different deco procedures etc. what works for me might not work for you and once in a while someone gets the bents or doesn't make it back at all.
now buy your SCUBA equipment, book that trip to the Andrea Doria and tell the captain you learned how to deco dive on a rep watch forum. :lol:
