For the Advanced Nitrox and Normoxic Trimix diver, the Ratio iX3M Deep is an open circuit advanced mix gad computer which is upgradeable in the future to full trimix and CCR.  Like it's CCR/Trimix sibling the Ratio iX3M Tech+ the 'Deep' has a double core algorithm Buhlmann ZHL16B + VPM-B pre-installed and running in real time. With an ability to work with 3 gases (max ranges O2: 18-99% He:0-50%) it's easy to switch between air, gauge, nitrox, normoxic trimix modes. The unit is also future-proof and further upgradeable to iX3M Reb software and casing/CCR connection.

The iX3M boasts the biggest high contrast wide angle (150°) view IPS technology screen on the market with a wonderful QVGA 2.8 inch colour display at 144 dip resolution and is fully customisable with your favourite colours with easily readable big bold letters. Rated to 300 metres, the unit has repetitive dive management, deep or pyle stops, salt and fresh water choices, on-the-fly setting changes in any mode, full deco table screen, tissue saturation charts and much much more.

With its upgradable firmware the iX3M, with 40 hours runtime on dive mode on a single charge, also comes with a number of pre-installed apps available at the push of a button. GPS, Magmeter, Chrono, Pitch & Roll, Moon Phase, Luxmeter and the Mix Analyser (to use to the external analyser) are just some of them available immediately and developers are working on more with user feedback - the most recent app to arrive is Gas Blender to calculate Nitrox and Trimix mixes.

The iX3M for Open Circuit Normoxic Trimix and Nitrox

The iX3M Open Circuit mixed gas dive computer (iX3M Deep) is programmable to 3 gas mixes and has a 300m depth rating like its full trimix (OC/CCR) sibling the iX3M Tech+. The computer is cased in a rugged polymer body with a transparent Mackrolon screen that's screwed down using 12 stainless star bolts, giving it a depth rating of 300m. Like all iX3M's the Deep version also runs real time and pre-installed Buhlmann ZHL-16B or VPM-B algorithms. The iX3M Deep has user settable safety parameters.

All 'control' of the iX3M is through 4 buttons at the base of the unit with a simple menu system allowing on the fly adjustments for almost anything and in any mode.

It's 2.8 inch display with clear bold letters under a Makrolon top glass is one of a kind, easy to read, boasting a high contrast wide angle (150°) view IPS technology screen with wonderful QVGA colour at 144 dip resolution and is fully customisable with your favourite colours.  

The unit comes with its USB connection cable (PC/MAC and charging interface) and its firmware can be upgraded via the internet alongside downloads and upgrade of unit specific apps.

Ratio iX3M Deep Computer

The iX3M Deep is an advanced technical dive computer which can only be used for Open Circuit diving. (For Closed Circuit Rebreather | CCR and full trimix, check out the iX3M Tech+) . The Deep has 3 user definable mixes programmable from 18 to 99% O2 and 00 to 50% He.

With a complete dive planner/simulator built into the unit, the iX3M has visual, acoustic and vibration alarms, a compass screen, stopwatch and magnotometer that can be used underwater and on the surface. 

Reliable Software & Algoritms

The core of any dive computer is its software and the algorithm it uses, what pre-installed algorithm(s) it comes with.

Ratio iX3M computers are based on a true double core algorithm pre-installed at production. Both the Buhlmann ZHL16-B and the VPM-B algorithm are installed as complete versions and run in real time.

The iX3M series integrates the real and complete algorithm to calculate your current tissue saturation and decompression profile in real time. This allows to obtain reliable and very safe decompression profiles.

The iX3M Real Time algorithms are so flexible that you can also change their conversatism during a dive.

Starting a dive, all you have to do is chose from the iX3M menu which algorithm to use and optionally add/adjust the safety factors for that algorithm.

For Gradient Factors you can adjust GFlo/Hi and for VPM you can adjust the starting Critical Bubble Radius (R0).

The iX3M allows you to change the conservatism even during a dive to reduce or extend the TTS in a appropriate deco curve.

Plese note, only the iX3M Tech+ and the iX3M Reb allow adjustment of GF or R0 while iX3M Deep only lets you change the conservatism level (PS) for the dive.


Repetitive Dive Management

More dives a day in more days? No problem at all. 

With its real time algorithms the iX3M calculates your real tissue saturation status and calculates your repetitive dive profile according to your previous dives. This means the profile is always optimised, even after days of repetitive diving.

Manual Gas Management

The iX3m kets you easily perform a gas break or manuallty manage mix changes i.e. anticipating the scheduled mix change at a different depth. With its easy menu and bold buttons, you have complete control over your technical dive.

Deep, Deco and Safety Stops

Fully customisable, all of them! Safety stops in your agency's style: Set the depth and the time of your safety stop. Deep Stops in multiple ways: Deep stops off, with standard method or with Pyle stops, it's up to you. Deco stops in your style: Set the Deco steps for every range of depth you want. The iX3M will do the math for you.

Ambient Light Sensor

Optimising autonomy and readability, Let the iX3M automatically regulate the luminosity of the screen in real time, but if you prefer you can set your favourite fixed luminosity level.


Vibration Alarms

The iX3M has alarms only you can feel. In addition to the traditional and acoustic alarms the iX3M features a very powerful vibration alarm. So powerful, you will feel it through your dry suit. But like everything with these units, the alarm is adjustable and is user dependent.

All the information you want

The Ratio iX3M can tell you more or less everything to do with your dive. Using one button at any stage of the dive you can see your full deco table (where deco is required, a graphic illustration of your tissue saturation and the HD Dive Profile.

Full deco table: Not only a global Time To Surface (TTS) but all the deco stops, time and mixes to be used are displayed. Tissue Saturation: Displays current tissue saturation level. During decompression it will display which tissues have to be desaturated to continue the ascent. HD Dive Profile: The graphic of the cyrrent dive diagram updated real time during the dive and displayed in a gorgeous, bright and big 2.8ic. 144 dpi resolution colour screen.
