What dive computers use Buhlmann?

The Descent Mk1 (currently the only dive computer by Garmin) utilizes the Bühlmann ZHL-16C algorithm and has highly configurable conservatism settings.

What algorithm does Aqualung use?

Pelagic Z+
Dr. Lewis wrote the proprietary Pelagic Z+ (PZ+) algorithm employed in Aqua Lung’s computers. The PZ+ algorithm is based on the Bühlmann ZHL-16C algorithm and is a favored recreational algorithm for the safety conscious diver.

What algorithm does Shearwater Perdix use?

Varying Permeability Model
Shearwater Research Upgrade to VPM-B Deco Algorithm Features The Varying Permeability Model (VPM) is a decompression algorithm that attempts to predict the behaviour of bubbles within the human body during decompression.

What is conservative factor dive computer?

Generally speaking, conservative means safer. In practice it means that a dive at a given depth is shorter due to the decompression obligation (the no decompression time is short). Conservative also means that the time the diver needs to spend on decompression is longer.

What algorithm does Suunto use?

The Suunto RGBM Heritage 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.

What is gradient factor in diving?

Developed by Erik Baker, gradient factors allow divers to adjust exposure limits to become fractions of another limit. Gradient factors are commonly used with the Bühlmann algorithm, a well-researched set of decompression procedures for which the underlying source code was openly released to the community.

Does the Shearwater Peregrine have a compass?

The Peregrine is a simpler dive computer focused on single gas air and nitrox diving, and light 3-gas nitrox technical diving. The Perdix is a more advanced computer for all types of diving including Trimix and CCR with additional features such as a digital compass and air integration.

What does gradient mean in scuba diving?

The Gradient Factor defines the amount of inert gas supersaturation in leading tissue compartment. Thus, GF 0% means that there is no supersaturation occurring and inert gas partial pressure equals ambient pressure in leading compartment (Note: The leading TC is not necessarily the fastest TC!).

What does GF mean in scuba?

Low Gradient Factor defines the first decompression stop, while High Gradient Factor defines the surfacing value. Using this method, the GF actually changes throughout the ascent.

What does GF mean in diving?

Gradient Factors
Setting your conservatism levels in this mode can be as simple as selecting from 3 settings: Low, Medium or High. There is a fourth setting called Custom. We recommend that divers refrain from tweaking the custom settings until the diver is familiarized with Gradient Factors (GF).
