Shallower dive then deeper dive?

[drbill]

I do reverse profiles quite frequently with no ill effects. Much of the early work on their acceptability was done by as friend of mine, Jon Hardy (the founder of SCUBA Lab but now deceased) However I adhere to a good surface interval and follow my computer (and brain).

I wouldn't make a habit of it but if you are careful I doubt a single reverse profile will result in any ill effects.

Thanks for all of the info re. reverse profiles. Was able to pull up a great deal of information w/ a couple of searches. Think that I'll continue to hunt around for the dive I want in the morning but, absent that, will give it a try.

Again, thanks.

Have always tried to comply with the rule re. deeper dives followed by shallower dives. On an dive trip I'll be doing in February, it appears that the deeper wreck dive I want to do (around 100 ft) will be in the afternoon. Divers offered in the morning are shallower reef dives. Anticipate using nitox (32%). So, increased risk of decompression sickness if do shallower dives followed by deeper ones?

Thanks,

Hal

i do reverse profiles and incorporate deep stops into every dive. after reading and studying the theory as posted by GUE-WKPP on deepstops, PFO and blood circulation time in the body, i think JJ theory works if applied properly.

Tho this does not sit well with the PADI instructors that manage the resort... shhhhh..... solo diving is 'enforced' ( sad part...
