DTS · Gas Guru v1.7
DTS Gas Guru is a professional technical diving gas planning app built specifically for technical and CCR divers. Four precision tools. No guesswork. No spreadsheets.
Available now
Every tool supports both open and closed circuit. Just accurate, reliable calculations, exactly when you need them, on the boat, at the fill station or in the classroom.
The Tools
Calculates the optimal gas mix for any depth based on your desired PO2, gas density and narcotic level. Nitrox, Trimix and CCR diluent modes, with CCR defaults aligned to RESA and ISO standards.
Unique to Gas Guru Calculates the optimal helium fraction based on your gas density limit and actual water temperature, a level of precision no other app offers.
A real-time gas density calculator with colour-coded Safe / Caution / Critical thresholds for OC and CCR loop gas, factoring in N2, O2 and He. CCR diluent limits align with RESA and ISO standards but are user adjustable.
Unique to Gas Guru Input your actual water temperature for a truly accurate gas density prediction, a world-first feature currently unavailable in any other app.
Check the full properties of any gas mix at any depth, PO₂, EAD, END and more. Indispensable for CCR divers assessing diluent options.
Unique to Gas Guru Displays three simultaneous MODs, one each for your PO₂, gas density and narcotic depth limits, factoring in water temperature and your O₂ narcosis preference.
Top-up and from-empty gas blending with ideal gas and real gas Z-factor precision modes, taking filling temperature into consideration. Trimix and Nitrox planning with real gas precision.
Unique to Gas Guru Fully adjustable O₂ and helium purity to account for real-world cylinder supply, with top-up gas configurable from air to any nitrox or trimix blend.
