bühlmann

I’m coding a dive computer algorithm using Bühlmann’s ZHL-16C model. So far, I’ve implemented it successfully without incorporating any conservatism. Now, I want to add Gradient Factors (GF). My main reference is Erik C. Baker’s article "Clearing Up the Confusion About 'Deep Stops'". In the...

Hi, I'm looking for advice on which backup computer I can buy used and at the cheapest price that has the Buhlmann algorithm with customizable GF. GF must be customizable so I can have the dive profile match my primary computer (Perdix). I'm thinking a used Petrel might be my only option, but...

With Shearwater supporting DCIEM upgrades for commercial and military applications, I thought this might have been discussed here but haven't found much with searches. I live and dive around Victoria BC, and have done some contract work on the boats that the Canadian Navy Fleet Dive Unit use...

Has anyone come across the actual algorithm that can be used in MS Excel?

I got a good deal on a set of ratio computer IDive Sports and actually bought the free instead of the easy (stupidity). Willing to pass along the savings to anyone interested. It's the Free version which does do Scuba but only does 1 gas mix and does not have air integration, the rest is the...

OK guys and gals science question. The basic concept (not to get overcomplicated) of a Buhlman deco model is to achieve supersaturation of the tissues in the case of the ZHL16 and when one of the 16 compartments reaches the supersaturation limit a stop is generated to off gas that compartment...

I am interested in knowing what are the theoretical and practical bases for planning decompression using gradient factors Low and High. That is, the reason behind choosing a Gf Lo and a different Gf Hi. Why ZHL-16C 40/70 and not ZHL-16C 70/70, for instance. The reason for introducing Gf (lo)...
