Lets say that after one minute the passage starts to go up. You will stop and sit out the remaining minute as to proceed would violate your decompression ceiling.

Ah now that is clearer ...I had wondered about the use(misuse) of that phrase. thanks for the explanation Clare and the question Ratcliffe

PS aparently I must " spread some Reputation around before giving it to Clare Gledhill again."

If DIR diving subscribes to doing definite things in definite ways, with diving equipment, styles, procedures etc, then how can Deco on the Fly be an acceptible method ? Surely everything must be "written in stone" as to what you are planning to do ?

I am genuinely confused here, as I assume Deco on the Fly means that you can change it as you go, (as opposed to making it up as you go along, but you know what I mean) ?

Thanks!

thanks for asking that, clarified for me as well - greenies for you both

It's what happens when you leave your gauge-arm too close to the p-valve.

Merry Christmas all!

sorry for resurecting an old thread but found this quite interesting. everyone was told when they started diving that saw tooth and reverse profiles were bad. this was based on decompresion theory. (and theory it is) so how do cave divers go on with their up, down, up, down, carry on. do they rely on computers and pad the stops out. guess you can kind of plan the dive if you know the cave lay out, i'd love to try to use a wheel to plan it! are there depth time guide lines to keep within?
