The dive theory you need for the Divemaster and Instructor exams — physics, physiology, equipment, decompression, and dive planning. Drill each area with unlimited fresh questions.
Dive theory is the academic core of every dive-professional exam. Instead of re-reading manuals, practice the concepts directly: take a topic, answer a fresh set of questions, learn from what you miss, and repeat until each area is automatic.
A taste of the style. In the app you get a fresh set every time.
As a diver descends, the volume of a flexible air space (like a BCD) will:
Why: By Boyle's Law, as pressure increases with depth the volume of a flexible air space decreases.
Nitrogen absorbed by the body's tissues during a dive is released primarily:
Why: Absorbed nitrogen off-gasses gradually as pressure drops during ascent and after the dive, carried out through the lungs.
Physics, physiology, equipment, decompression theory (including the RDP/eRDPml), and the dive environment. These are the core of the Divemaster and Instructor exams.
The Divemaster exam covers all five dive-theory areas, typically requiring 75% per section. Focused practice on each topic is the fastest route to that.
