Decompression Model
Built on the Bühlmann ZH-L16C model with gradient factors, Pro Dive continuously updates a full 16-compartment tissue model during your dive — just like a dedicated dive computer.
Automatic Dive Logs
Every dive is saved automatically and synced to your iPhone:
• Full dive profile graph
• Max depth, duration, start/end times
• Min/max temperature
• Location via GPS + reverse geocoding
• Notes and dive-day details

Offline, Reliable, and Fast
All calculations run entirely on the watch — no signal required.
Your watch keeps logging even if the iPhone is not nearby.
