GoDive is a clean, ad-free dive calculator built for scuba divers who want accurate results without fuss.
CALCULATORS INCLUDED
• SAC — Surface Air Consumption
Calculate your air consumption rate from tank pressure, volume, average depth and bottom time.
• MOD — Maximum Operative Depth
Find the maximum safe depth for any nitrox mix and PPO₂ limit.
• EANx — Optimal Nitrox Mix
Get the ideal nitrox percentage for a target depth and PPO₂.
• Gas Density
Check whether your breathing gas is safe at depth. Alerts at the Mitchell & Doolette caution (5.7 g/L) and danger (6.3 g/L) thresholds. Works with air, nitrox and trimix.
• Bottom Time
Accumulate total bottom time across multiple dives for your dive log.
• Surface Interval
Calculate dive duration and surface interval between two dives.
• Ballast Converter
Find the equivalent lead weight between saltwater and freshwater.
• Altitude Diving
Calculate the theoretical sea-level depth to use with decompression tables when diving at altitude.
• Unit Converter
Convert depth, pressure and volume between metric and imperial.
