The complete
dive tool kit
A dive planner for Open Circuit and CCR, built on the Bühlmann ZH‑L16 algorithm with gradient factors. Plan multiple dive profiles, set up your tanks and environment, and see gas consumption, CNS and OTU for every dive. Plus diving calculators, a Shearwater dive log and a gas blender.

Tools
Quick answers to the questions you ask before every dive. Every tool works right here in your browser.
- MOD Maximum Operating Depth of a breathing gas with specific oxygen fraction limited by maximum oxygen partial pressure.
- ppO₂ Oxygen partial pressure at selected depth.
- EAD Equivalent Air Depth of breathing nitrox is a depth with the same nitrogen partial pressure as if breathing air.
- END Equivalent Narcotic Depth of a breathing gas is an estimate of a depth with the same narcotic effect if breathing air.
- EADD Equivalent Air Density Depth of breathing gas at selected depth.
- NDL No Decompression Limit for selected breathing gas and bottom time.
- Best Trimix Best Trimix gas for selected depth and Equivalent Narcotic Depth, limited by maximum oxygen partial pressure.
- Best Nitrox Best Nitrox gas for selected depth limited by maximum oxygen partial pressure.
- Gas density Breathing gas density at selected depth.
- Gas consumption Respiratory Minute Volume and Surface Air Consumption from a dive.
- Lift bag gas Volume of gas needed to lift an object from selected depth.

Dive planner
Plan Open Circuit and CCR dives with the Bühlmann ZH‑L16 algorithm and gradient factors. Deep Tools builds the full decompression schedule and shows you each step of the dive.
- Repetitive and multi‑level dives with bailout plans
- Profile with deco ceiling and tissue loading
- Stops, gas switches, CNS, OTU and gas consumption
- Pressure graph of every tissue compartment
- Lost gas plans, ready for your slate
- Share as file, text, slate or image



Dive log Shearwater
Import your dives straight from a Shearwater computer and see every detail of each dive.
- Full profile with ppO₂, CNS, TTS, SAC and gas density
- Dive sites pinned on the map
- Summary with deco model, gases and computer
- Buddies and colour tags, all searchable



Blender
Blend nitrox and trimix with partial pressure or continuous flow blending. Deep Tools works out every step from what is already in your cylinder.
- Mix to desired gas
- Mix with top off gas
- Continuous flow blending
