Description
For divers who want more control over how they plan and execute decompression.
The Shearwater VPM-B Algorithm Upgrade adds an alternative decompression model to compatible Shearwater dive computers, giving experienced divers additional flexibility when managing decompression profiles.
VPM-B (Variable Permeability Model) is commonly used in technical diving and offers a different approach compared to Bühlmann-based algorithms. This upgrade allows qualified divers to select the model that best aligns with their training, dive planning, and team protocols.
Why Divers Choose VPM-B
- Adds an alternative decompression model
- Used in many technical diving environments
- Supports advanced dive planning strategies
- Provides flexibility based on training and preference
This is a tool—not a shortcut—and should be used by trained divers who understand decompression theory.
