Scuba Diving Sim

A scuba dive simulator: control your buoyancy, watch your no-decompression limit, and respect your stops.

Dive. Watch the numbers. Surface on time.

A realistic recreational scuba diving simulator focused on buoyancy control, depth management, and real-time dive computer monitoring.

Stay within your no-decompression limit (NDL), or complete the required decompression stops before surfacing.

Important: Not for Real Dive Planning

This is a game and a simulation, not a certified dive computer.

Decompression, no-fly, and gas calculations are simplified and may differ from real dive computers, dive tables, and professional training.

Never use this simulation to plan, conduct, or make safety decisions about a real dive. Real scuba diving requires proper training, certification, and certified equipment.

Features

• Real-time dive computer — Track depth, dive time, NDL, ascent rate, decompression stop depth, and stop duration.
• Bühlmann ZH-L16C decompression model — Nitrogen loading is continuously calculated using gradient factors of 30/85.
• Realistic buoyancy control — Inflate or deflate your buoyancy compensator (BCD) and experience the delayed effects of buoyancy, depth, and lung volume.
• Dive safety and violations — Ascend too quickly or skip a required stop, and the computer will flag a violation, activate a lockout, and extend your no-fly time.
• Surface intervals and no-fly time — Review your post-dive status and see when your next dive or flight becomes available in the simulation.
• Repetitive diving — Residual nitrogen carries over between dives, affecting your next dive's NDL and decompression requirements.

Controls

• Buoyancy: [keys]
• Switch dive computer screen: Click/tap the display or press Tab
• Fullscreen: Use the button below the game window

Technical Notes

• Platform: WebGL — playable directly in your browser.
