It has been known for some time that deeper stops may be beneficial to divers. By keeping more pressure on divers during a deeper stop, bubbling may be minimized and gases may remain in solution. This promotes more efficient gas elimination by maintaining a driving force pressure gradient as compared to the slower process of algorithm that bubble absorption. This may also help with counter diffusion problems. The Minimized Bubble model uses an algorithm that calculates deeper stops.
Departure also has two other models.
One is a standard half-time model except that the first stop is calculated according to the Minimized Bubble model. This model is just what it is called. It was developed for divers that may not want to use the Minimized Bubble model, but who also may not want to use a pure half-time model. For those divers at altitude, Departure allows divers to choose between different altitude decompression and off-gassing models. Keeping with the theme of Departure, altitude divers can choose between standard models as well as unique proprietary models designed specifically for Departure.
