A TWO DIVE course covering the techniques for extending diving bottom time by following a multi-level profile planned on the PADI eRDP [Recreational Dive Planner], 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.
