IQ Dive Computer

IQ Dive Computer is a Connect IQ app for compatible Garmin watches that provides real-time decompression information. It computes and displays no-decompression time limits in real time, along with current depth and total immersion time. It also supports decompression dives. When no decompression times are exceeded, the app will begin to display and compute the decompression depth ceiling in real-time. The decompression algorithm is Buhlmann's ZH-L16. A dive planning feature allows the diver to determine allowable bottom times at different depths based on current saturation levels.
