Ratio IX3M2 Deep GPS dive computer: The dedicated multi-gas Air/Nitrox/Trimix (Normoxic) dive computer and depth gauge. Compatible with the Ratio wireless probe. Integrated GPS.
The Ratio iX3M2 Deep GPS dive computer is dedicated to technical diving with multi-gas management of up to 3x mixes. It can manage Air/Nitrox/Trimix normoxic dives and adds a simple depth gauge function.
This dive computer has a built-in GPS so that divers can easily find their way to the surface or mark a particular spot.
In terms of the algorithms used, the Ratio IX3M2 Deep GPS incorporates the combined Buhlmann ZHL16-B and VPM-B (Varying Permeability Model) algorithms.
The log book is very comprehensive, showing saturation profile, active mix, ascent rate, gradients, critical size of micro-bubbles, temperature, average and maximum depths, planning of next dives, etc.
A host of functions are integrated into the Ratio iX3M2 Deep GPS (on the surface), colour customisation, compass (usable underwater) with distance travelled, weather forecast, magnetometer, altimeter, thermometer, barometer, stopwatch, variometer....
An external oxygen sensor can be connected to the iX3M before diving to indicate the % O2 in the tank.
Its lithium battery provides between 20 and 50 hours of operating time, and can be recharged simply by plugging a USB cable into any charger.
You can connect the Ratio IX3M2 Deep GPS to your Windows or Mac computer via its USB cable or via Bluetooth with its DiveLogger interface.
