Nitrox Helper vs Poseidon Reef

Nitrox Helper is a Nitrox calculator designed for qualified EAN divers. Whether you're at the dive shop deciding on your mix or reviewing calculations before a dive, Nitrox Helper gives you quick, accurate answers with an interface designed for ease of use - even with cold hands. Your essential dive buddy for Enriched Air Nitrox (EAN) calculations. FOUR POWERFUL CALCULATORS Best EAN Mix Calculate the optimal oxygen percentage for your planned depth and PPO limit. Know exactly what mix to ask for at the fill station. Maximum Operating Depth (MOD) Determine the deepest safe depth for any Nitrox mix. Essential for dive planning and safety. Equivalent Air Depth (EAD) Convert your Nitrox dive to an equivalent air depth for use with standard Recreational Dive Planner (RDP) tables. Oxygen Partial Pressure (PPO) Monitor your oxygen partial pressure at any depth. Clear safety indicators warn you when approaching or exceeding safe limits. SALT WATER & FRESH WATER Calculate accurately for both environments. Sea water (10.0 m/atm) and fresh water (10.3 m/atm) use different pressure factors - Nitrox Helper accounts for this automatically. A read-only indicator on every calculator tab shows your current water type so you always know what you're calculating for. 8 LANGUAGES Use the app in your preferred language: English (UK), English (US), Afrikaans, Greek, French, Spanish, German, and Dutch.
