%%DD-MM-AAAA n°ID - Site - City - Country%% # Location **Site**:: Le Gibus **Sea**:: Mediterranean **City**:: Saint Cyr **Country**:: France # Parameters **Date**:: 2023-06-17 **Depth**:: 17 **DiveTime**:: 70 **DiveAt**:: 16:00 **SurfaceAt**:: 17:10 **Temperature**:: 19 # Gear **Suit**: 7mm semi-dry **Weight**:: 4 **Tank**:: Shark rebreather **Nitrox**:: constant ppO2 # Species - # Buddies - Mateo F. # Summary Second dive in a series of two rebreather initiation dives, using Shark rebreather. Making again some refresh on how to use it and immerge, but with a new exercice, at the end of the diving : flushing the fake lungs with O2 at 6m to reach the 1.6ppO2 (physiological limit of O2 concentration to breath). Great ballad!
