CCR dive computer RATIO iX3M [Gps] REB


Diving Computer Ratio IX3M [Gps] Reb: The dive computer dedicated to the rebreather dive. It can be connected to the recycler according to connectors on request. Compatible with Ratio wireless color sensor and integrated GPS.


The dive computer Ratio iX3M [Gps] Reb is a concentrate of technology for tek diver require. Ratio Computers is an Italian company that specializes in the manufacture of diving computers dedicated to technical diving.

The Ratio IX3M [Gps] Reb is specially designed for rebreather diving because it contains a possible outside connector for recyclers sensors (3 sensors O2 and 1x CO2 sensor can be connected directly to the computer). It also features via an external sensor can accurately measure the percentage of oxygen in a decompression tank before diving for example.

On the viewpoint of mathematical models, the ratio IX3M incorporates algorithms combined Buhlmann ZHL16-B and VPM-B (Varying Permeability Model). The user can manually change its gradient (Buhlmann model) and the critical bubble size (model VPM).

The IX3M ratio 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.

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 multi-gas dive computer Ratio IX3M [Gps] Reb also includes interesting features such as GPS (surface), color customization, compass (usable under water) with distance, weather forecasting, magnetometer, light meter, altimeter , barometer, stopwatch, variometer .... The Reb IX3M is a computer dedicated to rebreather diving as complete.

Its lithium battery gives it a range from 20h to 50h operating and simply recharge via a USB cable.

You can connect the IX3M Ratio to your Windows PC or Mac via its USB cable or Bluetooth with its interace DiveLogger.
