A TWO DIVE course covering the
techniques for extending diving
bottom time by following a
multi-level profile planned on the
Wheel version of the RDP, and
reviewing practical use of computers
whilst diving.
The first dive is on two levels –
progressing from deep to shallow,
the second dive is on three – giving
a stepped ascent profile.
Multi-level dive profiles are most
practical for recreational diving,
and the opportunity to use dive
computers under instructor’s
guidance is clearly beneficial. |
