Highlights
Outing Highlights
Your first truly quiet dives
The course emphasizes the hallmark of closed circuit rebreathers: a silent, bubble‑free underwater experience that extends usable gas and changes how you move and think beneath the waves.
No‑decompression skills to 100 feet
Instruction covers the necessary skills and procedures to safely conduct no‑decompression CCR dives to a maximum depth of 100 feet using air diluent, preparing divers for deeper, longer underwater work within those limits.
Hands‑on training with DIVERITE O2ptima CCRs
Training is conducted on DIVERITE O2ptima CM and O2ptima CCR units, giving students practical familiarity with current closed circuit hardware and procedures.
