HOW DOES IT WORK?
The PRECISION 3+ PRO Powermeter is so much more than a dual power meter. It's your training partner that offers peace of mind. While you are riding, your PRECISION 3+ PRO Powermeter will transmit watts, cadence, cycling metrics, and calories to your head unit of choice. While the power meter is not in use, Find My is enabled and allows you to see its location on a map. You can add your power meter to the Find My app and locate it on an iPhone, iPad, Mac or using the Find Items app on an Apple Watch.

AUTOMATIC TERRAIN SELECTOR
Detects the terrain you’re riding on for more responsive cadence and power feedback/data. Ride the roads less traveled with confidence.

CYCLING METRICS
Get more data like pedal smoothness and torque effectiveness to analyze and optimize your pedal stroke.

LEFT RIGHT BALANCE
A dual power meter measures the power from each individual leg to calculate your total power output.

ANT+ & BLUETOOTH
Get the same numbers training inside and outside. The PRECISION 3+ PRO Powermeter is both ANT+ and BLE compatible so you can use it on your preferred head unit and favorite indoor training app.

WATERPROOF
Based in the foothills of the Canadian Rockies, we were tired of training tools not designed to work in our tough environment. With an IPX7 waterproof rating you can be assured that your power meter can handle the toughest conditions.

3 YEAR WARRANTY
4iiii power meters are waterproof, durable, and designed to be accurate and precise even in the harshest conditions. Because of this, we are happy to offer an industry-leading 3-year warranty.

If the weather or climate make riding outdoors tough, your 4iiii PRECISION 3+ PRO Powermeter can be used with all popular indoor-training apps, such as Zwift, TrainerRoad, Wahoo SYSTM, Rouvy, and more. Simply use your favourite app's connection procedure over ANT+ or Bluetooth Smart, put your bike on a trainer, and get riding.
