Knowledge Development
The theory component builds on your Level 1 foundation with a deeper look into freediving physiology, the mammalian dive reflex, gas laws at depth, and risk management. Topics typically include:
- Advanced breathing and relaxation techniques
- Equalisation methods (Frenzel refinement, mouthfill introduction)
- Depth adaptation and the effects of pressure
- Safety protocols and buddy procedures at greater depths
- Recovery breathing and CO₂/O₂ training strategies
Most centres offer flexible learning formats, including online study followed by instructor-led review sessions.
Confined Water Sessions
In the pool or confined water site, you’ll work on improving static and dynamic apnea performance. Key skills include:
- Static apnea with a target of 2 minutes 30 seconds (PADI) or 2:30–3:00 (SSI)
- Dynamic apnea (horizontal swimming with fins) with a target of 50–70 m (165–230 ft)
- Buoyancy control, streamlining, and finning technique refinement
- Rescue scenarios including black-out and LMC (loss of motor control) response
Open Water Sessions
Open water training focuses on deep diving using techniques such as free immersion and constant weight. You’ll typically complete:
- Depth dives to 20–30 m (66–100 ft), based on comfort and performance
- Use of lanyards, dive lines, and depth markers
- Refinement of equalisation under pressure
- Freefall technique and streamlining at depth
- Buddy procedures and simulated rescues from depth
Conditions, water temperature, and visibility can vary, so some flexibility is built into each session. Wetsuits, masks, and long fins are typically required, and some centres may provide rental gear.
By the end of the course, you should feel more confident diving beyond beginner depths, with a solid grounding in technique, safety, and self-awareness.
