Triton mCCR Companion

A companion for divers on the M3S Triton chest-mounted mCCR. It works with no account and no signal — everything below runs offline. GUIDED CHECKS, WITH THE NUMBERS RECORDED Pre-dive and post-dive procedures step by step, against a live 3D model of the unit that focuses the part each step is about. It records what you measure, not just that you ticked a box: cell millivolts in air, O2 linearity against your analyzed purity and the barometric pressure, timed negative and positive leak checks with a reference cell, CMF flow, cylinder pressures and gas analysis. Anything you leave blank is reported as an omission rather than quietly passed. CELL LINEARITY THAT TELLS YOU THE TRUTH Expected millivolts are worked out from your own air readings and the actual O2 purity, then banded both ways — a cell reading high is flagged as clearly as one reading low. Log the station pressure and the app shows the calibration point a 100% flush is really worth today, instead of assuming 1.00 bar. 3D UNIT EXPLORER The whole unit, apart and labelled: both counter-lungs, the axial scrubber, the cell chamber, the gas path and every valve. Orbit it, pull it apart, tap any part for what it does and how it is serviced. DIVE LOG Import dives from a Shearwater over Bluetooth or from a file. Scrubber time carries across dives, cell trends are tracked over months, and each dive can be linked to the pre-dive checklist you actually ran before it. MAINTENANCE Service intervals for cells, mushroom valves, canister o-rings, the CMF orifice, the regulator, ADV, OPV, counter-lungs, hoses and the display — each linked into the explorer. OPTIONAL ACCOUNT Sign in only if you want your runs, cells and dives backed up and synced across devices. You can export or erase everything at any time. Training aid only. This app does not replace the manufacturer manual or formal CCR instruction. Verify every procedure against the current Triton manual and your instructor's protocol. Never dive a rebreather without unit-specific training.
