Simplest planer, safest dives

BullMix is designed for diving planing. From 3 parameters given by the user (the target depth, the Time aimed Bottom, and the Average Diver’s Consumption), the application gives the high and low Gradient Factors, the Time To Surface (TTS) and the total time of dive (RT).

BullMix takes care of the set of the calculations!
Moreover, BullMix:
- Recommends breathable mixtures adapted to an optimized decompression, even in case of switches to open circuit.
- Integrates the third rule and takes into account consumptions for the changes of tanks
- Gives the possibility to choose the volume and the pressure of one’s tanks.
- Allows to either optimizes tanks or decompression

- BullMix must be used with an adapted diving computer … And even in this case the decompression remains an inaccurate science, current models of decompression not taking into account physiological characteristics of their users.
- It is thus advisable to avoid behaviors and profiles suspected to be at risk
- The tips are based on the most reliable current data on decompression and gas management.
- BullMix is designed for divers certified by a competent diving organism,aware of the limits of decompression and aware of the habits to follow in case of symptoms or of suspicion of accident (DCS).
