Deep Tools vs Diveplanner Tec & Rec

The complete dive planner, dive log and dive calculator app for recreational, technical and rebreather divers. Plan decompression dives with Bühlmann ZH-L16 and gradient factors, import your dives from a Shearwater dive computer, blend nitrox and trimix, and get quick answers to the questions you ask before every dive. All in one app, for open circuit (OC) and CCR. Whether you are in dive training, planning complex deco dives, or logging your underwater adventures, Deep Tools gives you reliable results you can trust. DIVE CALCULATORS - Maximum Operating Depth (MOD) - Oxygen partial pressure (ppO₂) - Equivalent Air Depth (EAD) - Equivalent Narcotic Depth (END) - Equivalent Air Density Depth (EADD) - No Decompression Limit (NDL) - Best nitrox mix for depth - Best trimix mix for depth - Gas consumption (SAC / RMV) and gas density - Lift bag calculator DECO PLANNER * Plan complex dives with confidence on open circuit (OC) or rebreather (CCR): - Bühlmann ZH-L16B and ZH-L16C with gradient factors (GF) - Multi-level and repetitive dive planning - Lost gas plans and CCR bailout planning, with custom bailout points - Gas consumption, CNS and OTU for every dive - Dive profile, run time table, tissue pressure graph and slate view - Share dive plans as a file, text, slate or image DIVE LOG * - Import dives from Shearwater dive computers (Petrel, Perdix, NERD, Teric and more) - Full dive profile with ppO₂, CNS, TTS, SAC and gas density - Dive sites with name, coordinates, map and custom tags - Automatically merge dives with short surface intervals - Share dives with your buddies - Local backup and easy transfer to a new device GAS BLENDER * Mix accurate nitrox and trimix: - Partial pressure blending to the desired gas - Blending with a top-off gas - Continuous flow blending - Gas cost estimate MORE - Metric and imperial units - Altitude diving and water type (salt, fresh, EN13319) - Custom tank / cylinder database - Available in 11 languages * The deco planner, dive log and gas blender are included in Deep Tools Premium. Try them free during the free trial. Deep Tools is a planning aid. It does not replace proper dive training or certification. Special thanks to V. Paul Gordon, Serge Nelissen and Michael Heus for extensive testing and valuable contributions.

Diveplanner Tec & Rec plans recreational and technical dives, on open circuit or closed circuit rebreather (CCR), in a few taps, and keeps your logbook. PLAN • Bühlmann ZH-L16C decompression model with your gradient factors, or the Thalmann algorithm of the U.S. Navy: VVal-79 for air and nitrox, XVal-He-9 for heliox CCR dives; compare a plan with both • Open circuit and CCR, down to 300 m / 985 ft, in salt, fresh or EN 13319 water, at sea level or at altitude • Multi-level dives, multi-gas decompression with automatic or chosen switch depths • Contingency plans computed for you: deeper, longer, lost deco gas, GF 100 and the CCR bailout • Warnings for ppO2, END, gas density, isobaric counter diffusion, CNS and OTU • The decompression chart of each plan: the profile, the tissues' ceilings at GF 100 and at your gradient factors, the leading tissue • A dive day of as many repetitive dives as you need, with their surface intervals • Saved plans in folders, shared as files GAS • Describe your cylinders: the plan gives the pressure at the end of the dive, the turn pressure, the rock bottom and the maximum bottom time your gas allows • Gas needed by volume and weight, per gas TABLES • Dive tables by depth and bottom time for your own gases, gradient factors and conditions, with the previous dives of the day • Share or print the table as a PDF TOOLS • Gas blender: partial pressure blending of nitrox, trimix and heliox from what is left in the cylinder, ideal or real gas; the best mix for a depth from your ppO2, END and gas density limits, and the cylinder label • Tides: the tide of a day anywhere at sea, from the nearest NOAA tide station or the EOT20 global tide model, its high and low waters, and the tidal currents and slack waters of a nearby current station, read to the minute on the chart • Photo colors: restore the true colors of your underwater photos and videos, their blue or green cast, haze and missing red corrected, with the depth of your logged dive; compare before and after, then save or share LOGBOOK • Log your dives by hand, from a plan, or download them over Bluetooth from a Shearwater dive computer (Petrel 2, Perdix, Perdix AI, Nerd 2, Teric, Peregrine), with the profile, stops, gases and sensor values • Photos, dive sites on a map, statistics, tags, search and filters • Synchronised between your iPhone, iPad and Mac with iCloud • Export to UDDF, Subsurface, CSV, a PDF logbook and .divelog archives; import UDDF and Subsurface SHARE • Ready-to-cut dive schedules as a PDF, for your buddy or your slate: every plan, the gas and cylinders, CNS, OTU and warnings EVERYWHERE • iPhone, iPad and Mac • Metric or imperial units • In 12 languages, each with its user guide LICENCES • Rec, free: one gas, air or nitrox up to 40 %, down to 66 m / 210 ft • Tec Basic: up to 3 gases, nitrox up to 100 %, normoxic trimix and triox • Tec Advanced: unlimited gases and depth, hypoxic trimix • Try every feature free for 2 weeks Diveplanner is a planning aid. It does not replace training, experience, a dive computer or your own judgement: always dive within the limits of your certification.
