CCRSim app analytics for December 30

The number one rule of rebreather diving is to always know your PO₂. Oxygen sensors are the single most important component of a closed-circuit rebreather, yet they can and do fail. At depth, recognizing and responding to these failures quickly can make all the difference. CCRSim helps you build and maintain your reflexes by simulating realistic sensor failures. • Experience multiple failure modes: current-limited, fail-high, fail-low, erratic, frozen, and combinations of these. • Perform diluent flushes to check sensor response. • Inject oxygen manually via MAV taps to see how sensors behave at rising PO₂ levels. • Practice with one, two, or even all three sensors failing at once. This app is designed to help rebreather divers train their diagnostic thinking in a safe environment. With regular use, identifying faulty sensors becomes second nature, preparing you for real-world dives.
