Dive Toolbox

DiveToolbox — Professional dive planning and gas calculation tools for recreational and technical divers.

DECOMPRESSION DIVE PLANNER
Plan single-level and multi-level dives using the Bühlmann ZH-L16C algorithm with configurable gradient factors. Get detailed ascent profiles, gas switch schedules, and comprehensive safety analysis including CNS, OTU, gas density, and END
monitoring.

GAS BLENDING CALCULATOR
Step-by-step fill instructions for Nitrox and Trimix blending. Supports partial pressure and continuous flow methods with real-time MOD calculations.

MOD / EAD / END CALCULATOR
Instantly calculate Maximum Operating Depth, Equivalent Air Depth, and Equivalent Narcotic Depth for any gas mix.

GRADIENT FACTORS EXPLORER
Visualize how GF Low and GF High affect no-decompression limits and decompression schedules.

SAC RATE CALCULATOR
Calculate your Surface Air Consumption rate from dive data to improve gas planning accuracy.

ROCK BOTTOM CALCULATOR
Determine minimum gas reserves for safe ascent, including emergency scenarios with configurable safety margins.

SUCCESSIVE DIVE PLANNER
Plan repetitive dives accounting for residual nitrogen and helium tissue loading from previous dives.

UNIT CONVERSIONS
Convert between metric and imperial units for depth, pressure, volume, and temperature.
