PRECISION 3+
Powermeter

Features

• APPLE FIND MY
  Offering the peace of mind in knowing where your power meter is.
• 800 HOUR BATTERY LIFE
  With up to 800 hours of battery life, using the same CR2032 coin cell battery, you won’t have to
  worry about changing your PRECISION 3+ battery for years to come.
• ACCURACY IN 3D
  Not everyone has the perfect pedal stroke. With +/- 1% accuracy, 4iiii is the only crank-based
  power meter to use 3 strain gauges to measure all forces in your pedal stroke.
• 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.
• ULTRA LOW PROFILE
  With an ultra low profile design, the PRECISION 3+ Powermeter is compatible with more bike
  frames than ever before.
• INDICATOR LIGHT
  At a glance, you can now see when your power meter has turned on, performed a successful
  Zero-offset, or has a low battery. Although, don’t expect to see that low battery indicator for a while!
• ANT+ & BLUETOOTH
  Get the same numbers training inside and outside. The PRECISION 3+ 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
  A lot can happen in 3 years. You probably won’t need to use it, but it’s reassuring to know that all
  4iiii power meters are backed by an industry leading 3-year warranty.

Device Compatibility

4iiii PRECISION 3 power meters use both the ANT+ PWR and Bluetooth Smart Cycling Power Service standards, which makes them compatible with nearly every headunit, smartphone, or computer you wish to connect to.

Check your recording device documentation for ANT+ PWR or Bluetooth Smart (also called BLE, BTLE, or BT4.0) Cycling Power Service capability.

How does it work?

The PRECISION 3+ Powermeter is so much more than a power meter. It's your training partner that offers peace of mind. While you are riding, your PRECISION 3+ Powermeter will transmit watts, cadence, 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.
