Dive Tools & Calculators

Calculate Maximum Operating Depth (MOD), Equivalent Air Depth (EAD), and partial pressure of oxygen for any nitrox mix.

Calculate your Surface Air Consumption rate from tank size, pressure, depth, and dive time. See how your air consumption compares.

See how pressure, volume, and gas density change at any depth. Includes no-decompression limits and narcosis equivalent depth.

Enter the water temperature and your cold tolerance to get a personalised wetsuit thickness recommendation with product suggestions.

Estimate the total cost of a dive trip including flights, accommodation, diving, and gear rental for any destination.

Answer a few questions about your certification, experience, and gas mix to find out your personalised maximum depth.

Convert between bar and PSI, metres and feet, Celsius and Fahrenheit, litres and cubic feet, and more.

Calculate how much lead weight you need based on your body weight, suit thickness, tank type, and water type.

Select the marine species on your bucket list and we'll find the best destinations, optimal months, and build a multi-stop itinerary.

Calculate how much oxygen and helium to add for any nitrox or trimix blend using partial pressure blending.

Calculate how many minutes of breathing gas you have left based on current pressure, depth, and your SAC rate.

Look up no-decompression limits, pressure groups, and plan repetitive dives using recreational dive tables.
