Pool depth?

[SubMariner]

I heard another clause was that it was supposed to be lacking in current and such.

Yes, that's pretty much a given.

I have heard of a group around WPB that puts out some kind of trampoline floating behind their boat and does the confined stuff out in the OW over a 60ft deep reef that they are drifting along, the trampoline keeps the students pretty shallow though.

???? That certainly sounds like a lot of time, trouble & effort to go to rather than rent a pool. Frankly, there are too many variables to control for it truly to be "confined water". Whatever agency they're with, I don't think they'd take too kindly to this "un"confined water training.

How would you really be able to do bouyancy exercises or OOA ascent? Or 5 point descent? I'd love to see the typical OW novice trying to hover in 4' of water. Most struggle with 12'.

I don't see any way that a 4' deep pool prepares you properly for the certification dives. :11:

My thoughts exactly.
