Ratio IX3M [Pro] EASY Nitrox dive computer

Ratio IX3M [Pro] EASY Nitrox dive computer

Air/Nitrox dive computer iX3M [Pro]Deep Ratio : The dive computer dedicated to mult-gas diving Air/Nitrox and depth gauge. It is compatible with the Ratio wireless LED-color pressure gauge !


The nitrox dive computers Ratio iX3M [Pro] Deep is dedicated for diving Air and Nitrox

It is compatible with the brand new 3x led color wireless pressure transmitter from Ratio

The integrated algorithm of the multi-gas dive computer Ratio IX3M [Pro] Deep is a combination of Buhlmann ZHL16-B and VPM-B (Varying Permeability Model).

This version of the IX3M is also configurable on the deep stop increments. It will tell you the same "decompression table" of your ascent, indicating the necessary mixture, depth and time.

An outside oxygen sensor can be fixed to the computer before the dive to analyze the oxygen rate in your tank.

The log book is very comprehensive, indicating the saturation profile, active mixing, back to surface speed, gradients, critical microbubble size, temperature, average and maximum depth, planning the next dive etc ...

The Ratio IX3M [Pro] Deep also includes a color screen customization, a compass (usable under water) with distance, weather forecasting, magnetometer, light meter, altimeter , barometer, stopwatch, variometer ....

The computer is powered by a lithium battery that gives a range from 20h to 50h operating and simply recharge via a USB cable on any charger.

You can connect the IX3M [Pro] deep Ratio to your Windows PC or Mac via its USB cable or Bluetooth with its interace DiveLogger to have your diving history and parameters.
