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. In addition to using these different decompression models, Departure also allows divers to choose how they want to model the out-gassing during decompression stops.
Divers can choose an exponential loss model or a modified linear model.
Departure's decompression models are based upon the widely recognized half-time modeling. While, Departure may not have all the bells and whistles of some other programs, it does have a straightforward display that provides simple important information at divers fingertips. One way this is accomplished is by always displaying the decompression profile so a diver can experiment with changing parameters and then immediately see the results. Departure has many other unique features, but this article was designed to give only a brief background on its development. We invite you to experience Departure for yourself and experience it on your own.
