Ratio iX3M Pro

Ratio, Ratio
€ 699,00




As Big as it is Easy

The biggest most colorful display ever
Amazing high contrast.
QVGA 2.8 inch 144 dpi resolution color display.
With big and extremely readable characters.
IPS technology: for an astonishing wide-angle view.
Over 150° angle view for unrivalled clarity in every position of your wrist.

Super easy-to-use:
on surface and during the dive.
4 physical buttons: it's easier to get what you want.

A user-friendly menu and four mechanical buttons to navigate it.
HOME button: never get lost in the menu during a dive.
The iX3M's menu is easy to navigate but just in case you get lost, press the HOME button to go back to the dive screen.
Intutiveness at its best.

It can tell you everything:
In the easiest way, using just one button during the dive.
Full deco table: updated in realtime, throughout the whole dive
Tissue saturation: your current tissue saturation. During the decompression you can see which tissues you have to desaturate to continue the ascent.
HD Dive Profile: the graphic of the current dive diagram, in the magnificent 2.8inc. 144 dpi resolution screen. Updated in real time during the dive.
Manual management of the set mixes: the iX3M lets you easily perform a gas break or manually manage the mix changes, e.g. anticipating the scheduled mix change at a different depth. You have the complete control of your technical dive.
Change the conservatism, even during the dive: what if something wrong with your dive and you have not enought gas to respect the "Time To Surface"indication? The iX3M allows you to change the conservatism even during the dive to reduce the TTS and brings you to the surface in the safetiest way.
Disableable Deco control lockout: if you use the computer as a backup for your table-scheduled dive or for extreme cave diving, probably you will not (or can not) follow step-by-step the deco indications of the iX3M, causing the lockout of the computer. The iX3M allows you to disable the lockout to continue a coherent calculation of your deco and tissue desaturations anyway.
Planner: a complete planner inside. A real simulation your next dive. Simulate your next dive according to the current settings of the iX3M like mixes, conservatism, etc. and your previous dives. You have just to set the bottom time and the depth.Its more a simulator than a planner!!
And more of course: active mix, partial pressure of Oxygen, ascension speed, gradient factors (or critical bubble radius), OTU, CNS, temperature, average depth and maximum depth.

Ambient light sensor:
Optimizing 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.

Color-Coded Wireless Transmitter
A state of the art Wireless Air Transmitter that flashes green, yellow or red according to your tank's pressure during the whole dive.
You see your tank pressure from your ix3M, your buddy or your instructor from your CC Transmitter.
Rechargeable with the same USB cable of the iX3M.

Compatible with the new color-coded wireless transmitter:
- green: full to 100 bar
- yellow: 100 bar to 50 bar
- red: 50 bar to empty

Fully personalizable:
Your iX3M, your favorite colors.

Multi-tank transmitters possible:
Monitor up to 2 transmitters at the time
(Up to 2 for iX3M Easy, up to 3 for iX3M Deep and up to 10 for iX3M Tech+ en Reb)

Side mount mode:
Use multi transmitters with the side mount.
(Up to 2 for iX3M Easy, up to 3 for iX3M Deep and up to 10 for iX3M Tech+ en Reb)
Both the side mount tank transmitters on the same screen.
Tank auto-switch
Seamlessly switch between one side mount tank and the other one.
You just need to start breathing from the tank, the iDive will automatically change the transmitter shown on the RBT/BAR(psi) screen.
The iDive calculates the RBT (Remaining bottom time) considering all the Side Mount tanks have the same gas.

Repetitive dives management:
More dives a day in more days: no problem at all.
Featuring the real time algorithms the iX3M calculates your real tissue saturation status and calculates your repetitive dive profile according to your previous dives.
This means that your profile is always optimized, even after more days of repetitive dives.

Full deco table:
Everything is going as planned.
All the information about your deco, always at your fingertips during your tech dive.
Not only the global TTS, but all the deco stops, times and mixes to be used.
Updated in realtime, throughout the whole dive.

User settable safety stop:
Set the depth and the time of the safety stop.
Your certification agency will be happy.

Deep stops:
Deep stops OFF or with STANDARD method.
It's up to you.

Vibration alarms:
The iX3M has alarms only you can feel.
In addition to the traditional and acoustic alarms the iX3M feature a powerful vibration alarm. So powerful you can feel it even with a dry-suit.

Extended life USB rechargeable battery:
Does your smartphone have disposable batteries?
The iX3M has up to 40 hours of autonomy.
This is always visible at the top-left angle.

USB recharge:
One cable to rule them all.
You can use any USB port to recharge the iX3M, the wall charger of your smartphone is perfect.
You do not have to change the battery annually.
No risk of wear, humidity or seepage owing to the battery change.
You can use all computer functions without worrying about battery exhaust (backlight, compass, apps...).
You can recharge the iX3M wherever a USB port is.

Redundant strech-belts or redundant bungees:
You have just to choose. The iX3M comes with two redundant and extremely resistant Stretch-Belts with fast release system,
and it is ready to be equipped with the redundant bungees. 

Further functions:

Gauge AVG:
resettable average deth and timer. One button to rest the Average Depth, One button to reset the Timer, one button for the Compass.
Weather forecast: No one can control the weather, but we can forecast it !!
3D Compass self-compensating: extremely accurate 1 degree of resolution and +/-1 degree of accuracy. Tilt compensated up to 85° supported by a complete inertial platform. With visual and numerical indication of the direction and the reciprocal direction.
It always point to North even if it is not perfectly in horizontal position, because of its integrated accelerometer.
Magnetometer: are you looking for something big and made of iron?
The iDive cab sense the magnetic field of the earth and its variations caused by ferromagnetic materials.
Luxmeter: how much light do we have here? The iX3M vcan measure the ambient light.
Altimeter: with automatic altitude compensation for altitude diving.
Thermometer: Celsius or Fahrenheit.
Barometer: for the barometric pressure
Pitch & Roll: The iDive accelerometer indicates your grade, on both vertical and horizontal axis.
Moon phases: New, Waxing, Waning, Full.  Full, Waning, Waxing, New.

Chronometer: Ready, Steady, Go! Visualise partial times as well as the lap time.
Integrated Gas Blender: Just tell the iX3M what is inside your tank and what Mix you want to get. The iX3M will tell you how to make it. Both Nitrox and Trimix.
Oxygen analyzer:  computer with Oxygen Analyzer Integration (sensor optional). Simply plug the accessory to your iX3M and transform it in a professional Gas MIx Analyser with a real time completely automatic Gas analysis. Using its sensors the iX3M check the correct calibration and the atmospheric conditions to make a perfect analysis of the Oxygen % inside the tank.
