Triton Rebreather Pre-Dive Checklist

This Triton closed-circuit rebreather (CCR) pre-dive checklist guides divers through essential safety and equipment steps before entering the water. It covers personal readiness, oxygen and diluent/bailout contents and pressures, PPO2 display checks, battery status, and air calibration. It includes scrubber canister packing and leak tests, counter-lung inspections, loop integrity and pressure tests, gas line and first stage connections, electronics and cell housing checks, and positive/negative pressure checks. Final steps include oxygen flush and calibration, Shearwater verification, BCD and ADV function checks, a 5-minute pre-breathe, and pre-dive safety checks with O2 and diluent flushes at depth.
