Suunto D4i interactive learning tool
Set up your diving modes (air and nitrox), pair the computer with a transmitter and access the memory log book. Or just make virtual dives! Suunto Algorithms
At the heart of every Suunto dive computer Is an algorithm—the reduced gradient bubble model (RGBM)-that calculates decompression for a dive. Relentlessly pursuing ever best models for divers of all types, Suunto continues to push for
RGBM perfection. Suunto has been developing RGBM algorithms together with Dr. Bruce Wienke for well over a decade.
