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.

Suunto DM5

The Suunto DM5 allows you to download your dive logs for advanced analysis and create dive plans. Transfer dive logs from your compatible Suunto dive computer, upload dive plans, and customize your dive computer.
