DiveCalc: Scuba Dive Planner

DiveCalc: Your Scuba Diving Calculator & Dive Planner (Recreational & Technical)

Plan your dives with confidence, precision, and safety. DiveCalc is an essential toolkit designed for recreational scuba divers, Divemasters, instructors, and technical divers (Tec / Trimix) looking to streamline dive planning calculations and master dive theory.

Unlike basic calculators, DiveCalc doesn't just display raw numbers: it explains the physics and formulas behind each calculation. Deepen your understanding of dive science, boost your safety margins, and make better-informed decisions underwater.

🛠️ KEY FEATURES & DIVE TOOLS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚡ Best Gas Mix (Nitrox & Trimix)
Quickly determine the optimal gas blend for your target depth based on your selected Maximum PO2 limits (1.4 / 1.6 bar).

🫁 Gas Consumption & SAC / RMV Rate
Calculate your Surface Air Consumption (SAC) and Respiratory Minute Volume (RMV). Accurately estimate total gas requirements for any dive based on tank size and personal breathing rates.

🛑 NDL Tables (No-Decompression Limits)
Access clear NDL tables categorized by training agencies and gas types. Plan your bottom time safely within recreational boundaries.

⚠️ Gas Density Calculator
Determine gas density at maximum depth. Prevent excessive work of breathing (WOB) and mitigate CO2 retention risks on deep dives.

🎯 MOD (Maximum Operating Depth)
Calculate exact depth limits for any breathing gas blend based on custom partial pressures of oxygen (PO2).

🧠 END (Equivalent Narcotic Depth)
Estimate the narcotic impact of helium-based Trimix blends compared to diving on air at 30 m (100 ft).

💨 EAD (Equivalent Air Depth)
Calculate your EAD for Nitrox blends to easily cross-reference and plan using standard air decompression tables.

⛰️ Altitude Diving (TOD - Theoretical Ocean Depth)
Convert high-altitude lake dives (>300 m / 1,000 ft above sea level) into equivalent sea-level depths for safe decompression planning.

🎓 MASTER DIVE THEORY & SCIENCE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Ideal for students preparing for certification exams (Open Water, Advanced, Enriched Air Nitrox, Rescue, Divemaster, Instructor, or Tec 40/45/50) as well as certified divers looking to refresh their understanding of dive physics and physiology.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚠️ DISCLAIMER & SAFETY NOTICE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
This application is an educational and supplementary planning tool intended strictly for certified divers or individuals under the direct supervision of a certified instructor. Incorrect dive planning can result in severe injury or death. While calculations are thoroughly checked, accuracy cannot be guaranteed under all conditions. Always verify your calculations with your primary dive computer and official dive tables. Use at your own risk.
