iDive Sport TX

Dive Watch Computer.


Compatible with the CC Wireless Transmitter.

iDive is fully compatible with the RATIO Wireless Transmitter.
This way, you can view the pressure of your tank directly on the iDive display.

RATIO Wireless Transmitter


The RATIO CC Transmitter (Color Code) is the world's first wireless transmitter that lights up green, yellow, and red based on the remaining tank pressure throughout the dive.



You can see pressure and remaining time directly on your iDive, and your buddy or instructor can also see them via your transmitter.




Rechargeable with the same USB cable as your iDive.





Yes, you can also turn off the transmitter light, to keep your pressure just for yourself!


Super Readable Display

BIG and Bright Numbers.


The dive data on the iDive screen are 15% to 30% larger than any other watch-computer in its category, thanks to the 80x80 pixel (fully) dot-matrix display.


Bright, brighter, brightest: Adjust screen brightness and contrast as you like. The iDive has a long-lasting rechargeable battery, so you can light up the screen as much as you want without worrying about draining it.






Super readable screen both underwater and on the surface.

iDive Sport uses a trans-reflective screen.
This means the more light there is, the easier it is to read.

Perfect for use even in full sunlight.




iDive is Fully ARMORED

Built to withstand your dive ...
or a hammer.






> Full Armored Stainless Steel Buttons <
Designed to offer maximum resistance and waterproofing even in extreme conditions.



> Stainless Steel Bezel and Case Back <
Marine-grade steel components for ultimate durability and strength.



> Heavy-Duty Polymer Case <
Shock-resistant, durable, and lightweight: ideal for intensive and professional use.

The size of a real watch.

Made to stay on your wrist all day.
Slim and lightweight.


And the wetsuit strap extension is always included.


  Rechargeable   with Super Battery Life.

Up to 2 months of battery life with daily use,
then just recharge it via USB cable.



iDive features super-efficient battery management.

RATIO Wireless Transmitter



If iDive detects it's been still for more than 5 minutes, it turns off the screen, reducing power consumption by over 80%.



As soon as it senses movement, it reactivates in less than 80 tenths of a second.



iDive can last up to 25 hours of diving on a single charge,

can reach 2 months of battery life when worn as a daily watch,

and up to 6 months when used only as a dive computer.



USB Rechargeable.

Still using high-tech products with disposable batteries?



You can recharge the iDive from any existing USB port.



Because rechargeable is better:

You avoid the yearly "battery replacement tax",


No risk of wear,
moisture or leaks due to battery changes.
Have you noticed that after the first replacement, batteries tend to run out faster?


You can use all features without worrying about battery drain (Backlight, Compass, Apps…).


You can recharge anywhere there's a USB port.
Ever tried changing a battery in the Maldives or on a boat?


  Integrated Super Compass.  

3D auto-compensated via accelerometer
with ±1 degree resolution.

Extremely accurate, with heading and reciprocal indicator.



Automatically compensated by the accelerometer, always finds North even when tilted.


Advanced Repetitive Dive Management.

Multiple dives per day over multiple days: No problem.

Using its Real-Time algorithms, the iDive doesn't just apply a penalty percentage to your dive profile, but directly integrates your current tissue saturation status into the decompression calculation.




This means your profile is always optimized based on your actual physiological status, maximizing safety and performance even during multiple consecutive dives over several days.


Dual Deco Algorithm *

You get both Bühlmann and VPM.

You can choose directly from the iDive menu which decompression algorithm to use for the dive.

*available only on iDive Sport Deep and iDive Sport Tech+




Gradient Factor and Bubble Radius freely adjustable*
Configure the algorithm as you prefer, even during the dive.

*available only on iDive Sport Tech+






Deco Table, during the dive.

Deco Planner before the dive, and Deco Table during.
All Deco Stops displayed during the dive, for both Bühlmann ZHL-16 B and VPM-B.


  GAUGE AVG Mode.  


Only the essentials.
With resettable average depth and timer.




If you prefer, you can set the iDive to work as an AVG depth gauge, calculating only depth, time, and averages.





One button to reset the average depth,
one button to reset the timer,
one button for the compass...

...and nothing else.


NITROX Analyzer



The world's first Dive Watch Computer that can Analyze NITROX.




Simply connect the analyzer to the iDive to turn it into a professional Gas Analyzer.



The NITROX Analyzer has access to all iDive sensors and its processor.


In addition to using its computing power for automation, it also checks if the atmospheric conditions have changed since the sensor was calibrated.



If conditions have changed, it will recalibrate the sensor automatically.
Awesome, right?
