Bühlmann ZHL-16C Algorithm

Bühlmann ZHL-16C Algorithm

Our dive computers use this algorithm to calculate tissue loading, NDL and decompression information. It considers the current depth, time and breathing gas to output to determine how gases enter and exit the body due to pressure changes. You can set conservatism according to your body and dive conditions.
