Uwatec problems

[FreediveWI]

On trimix dives our stops start deeper than 100'.

For the wrecks around here I started doing deeper stops a while ago- as soon as I read Pyle's article's in the early 90's. My typical stops when scuba diving on the Willy are to do a minute at 60'( top of the wreck) followed by another at 50',40',30',20'and 10'. This will clear out your body pretty well and get you out of the water with less fatigue. My stop time is only about 7 minutes, but it's "where and when" the stops take place that is most important. These stops also don't take into account what I am breathing and any deco obligation that I might have as a result. Sometimes I use air and other times I use nitrox. My last few "scuba" dives on the Willy had me using triox. I would add in any deco obligation on top of the stops mentioned.

The idea is to keep the bubbles small enough that they don't cause any more problems on the ascent. The old tables had you shoot up to the shallows and hang out there forever. Esentially you were "bending" yourself on the quick ascent from depth and "fixing" yourself during the long stops. The new(er) theory has you avoiding the injury phase of the dive altogether.

It works for rec and tec.
