DTS Dive Planner

DTS Dive Planner is a technical dive planner for open-circuit and closed-circuit rebreather (CCR) divers. This app is the free companion to your DTS account: sign in with the account you already have and your plans, gases and settings are with you on the boat, on the dive site and in the classroom. An existing DTS account is required. The app signs in only and does not create accounts. Plan the dive - Decompression schedules on Bühlmann ZHL-16C with configurable gradient factors, ascent strategy, o2 tracking and gas switching techniques - Open circuit and CCR as full dive modes, with easy setpoint and diluent selection. - Multi-level and repetitive dives across a day or a trip - Trimix, travel, stage and deco gases, with every gas switch shown on the schedule - CCR bailout planned as its own schedule, from the depth you choose - Max bottom time, lost-gas analysis and plans re-run deeper or shallower, longer or shorter - Altitude and water type taken into every pressure figure Know your gas - Gas requirements per cylinder, turn pressures and min gas - CNS and OTU oxygen exposure, with air breaks - Gas density, END and MOD on every mix, and isobaric counterdiffusion (IBCD) screening on gas switches - Warnings stated in words beside the figure they belong to Gas tools - Best Mix, Gas Check, Density and SCR calculators - An enhanced Gas Mixer that works out blends and problem solves. Definable helium and 02 purity with the ability to account for custom nitrox and trimix banked gasses - A Mix Library of your own working mixes, synced to your account. Set up your personal or agency's standards gasses. Log and team - A dive log with dive sites and maps - Team plans: send a plan to your team, and each diver then approves against their own cylinder volumes and SAC rates. - Print, save or share the plan sheet from your phone Made for the water - Works offline after your first sign-in - Your dive log, plans and settings sync end-to-end encrypted, so we cannot read them - Metric or imperial, in eight languages: English, German, French, Italian, Spanish, Russian, Indonesian and Japanese - No ads and no tracking Built and tested by technical divers at Black Water Tek. Safety DTS is a planning aid only and carries no guarantee. It is for divers trained in mixed-gas decompression by a recognised agency, and it is not a substitute for that training. A decompression model is based on an average, not your personal physiology. Cross-check every plan as per your training, follow your dive computer in the water, and plan within your certification. You dive it at your own risk.
