Controlled Ascent Question

[TMHeimer]

In mentioning 20 feet I'm of course saying that that is your deepest depth, but yes I still ascend slowly just as a good habbit. It would be interesting however to know if it is possible to come up too fast from 20 for the respiratory system to offgas enough N to be safe- assuming no reverse block. Just an interesting question.

Everytime you ascend it should be controlled and slow, now your dive table (which I use) or your computer will tell you when to make a decompression stop if one is needed. I have been on dives in which the max. depth was 25 ft. and no decompression stop was neccesary, and I have been on dives that are 50+ ft. max. depth in which decompression stops are needed. When you take your open water course, your instructor will explain the tables and computer to you. Hope this helps

I think you are refering to a safety stop. Decompression stops only happen in emergency situations for recreational divers.

Good stuff. A good habit of slow ascents never goes to waste. Safety is where it is at to ensure fun diving ahead. Good luck w/your certs. Welcome to the site.
