4iiii Dura-Ace R9200 Precision 3+ PRO Wattmåler

From training in the rain to the most challenging races, the 4iiii Dura-Ace R9200 Precision 3+ PRO powermeter will always give you the data you need. With a battery life of up to 550 hours, IPX7 certification, an automatic terrain selector and +/-1% accuracy, you will gain insight into your performance and be able to optimise your workouts.

Double-sided or single-sided?
A double-sided power meter is a bit heavier than a single-sided power meter, but provides you with even more accurate and comprehensive data. The double-sided measurement, as in this 4iiii Dura-Ace R9200 Precision 3+ PRO, displays information from both legs, making it easy to spot left/right differences, for example. A single-sided powermeter simply doubles the single-sided measurement. With an accuracy of +/- 1%, this powermeter delivers highly accurate information about your pedal stroke.

"Apple Find My" & Automatic Terrain Selector
Thanks to 'Apple Find My' support, you can see the location of your powermeter with an Apple smartphone, iPad, Mac or Apple Watch. All you need to do is add the powermeter to the app. Even when the power meter is not in use, this way you can always see where your bike is. Furthermore, the new feature 'Automatic Terrain Selector' has been developed, which can detect different types of terrain. The powermeter then automatically switches between different methods to measure cadence, ensuring that your power output is accurately measured on any terrain!

Battery life
The 4iiii Precision 3+ Pro does not have an internal battery, but uses button cell batteries. The downside of this is that you do have to replace these from time to time. Fortunately, the battery lasts up to 550 hours, which is a lot longer than most internal batteries in powermeters and your favourite indoor trainers. Furthermore, the powermeter has an IPX7 waterproof rating. This assures you that the powermeter works well even in wet conditions.

Connectivity
This power meter transmits both an ANT+ and a Bluetooth signal. This makes this power meter compatible with almost all bike computers. If you're not sure if your bike computer or sports watch is compatible, you can check your computer's user manual to see if it is ANT+ or Bluetooth compatible and power meter compatible.
