The Ratio iX3M dive computer is a hugely impressive platform that offers so much for technical divers. In fact the iX3M is available in three different models that add more technical features as you progress up through the models.
The iX3M Easy Pro is the recreational diver model that offers two air / nitrox gas mixes and isn't fitted with the GPS and Bluetooth hardware to keep the cost down. The iX3M Deep is their entry tech model which gives support for three Trimix gas mixes. The iX3M Tech+ allows up to ten Trimix gases, adds user settable Gradiant Factor and Critical Bubble Radius, increases support gas percentages and widens the PO2 range. The iX3M Reb adds rebreather support with up to three Diluents and a connector for the sensor board.
Comparative technical specification and features for each model are shown below:
