The new VPM-B decompression algorithm available for the Shearwater Predator & Petrel.

The MultiDeco program is an extension to the V-Planner program. It adds more deco models in one place. But the VPM part is all the same in both. The same is true for our X1 V-Planner Live and MultiDeco-X1 programs.

You can actually run both programs on your Android device together, though neither will know the other exists.

Features

VPM Bubble Models
VPM or the Varying Permeability Model is a decompression algorithm that attempts to model the behavior of bubbles within the human body during decompression. The algorithm was initially developed by David Yount in laboratory testing and coded into Fortran by Erik Baker. 

The Shearwater Implementation 
Shearwater Research has implemented VPM-B according to the original Erik Baker Fortran specification. In addition to implementing the Baker model, Shearwater Research has added a new option. VPM-B dive profiles often have deep stops to control bubble formation with reduced time at shallow depths. The reduced shallow depth time can be quite aggressive with VPM-B so Shearwater Research has included a VPM-B Gradient Factor Surfacing (GFS) option. VPM-B/GFS allows VPM-B dives to be executed while ensuring that a gradient factor of 90% is never violated.
