You place scuba sets at strategic places around the dive site - probably at
the max depth. The snorkellers then do their normal thing except that instead
of going back to the surface for a breath they can get a quick "refill" off
any of the cylinders on the bottom.
I suppose that the advantages are:
- the diver is unencumbered by all the kit
- many free-divers can be in the water with only a limited number of
scuba sets.
- the free-diver can stay down longer
The main danger of this is that the snorkeller will do a breath-hold ascent
after breathing from a scuba set at depth. Although I would guess that there
may also be problems of effective, excessive skip breathing and decompression.
