Power meter specialist 4iiii Innovations has announced its latest firmware update to its PRECISION 3 Powermeter.
4iiii adds that… ‘PRECISION 3 retains its extremely low profile, 800-hour battery life, and stellar accuracy, but adds Gyroscope and more responsive cadence and power output. 4iiii has taken a new look at the cadence algorithm, the sensors used, and when they are used based on innovative new development processes.’
Features of the 1.2.0 Realtime Terrain Auto-Optimizing Firmware update:
- Specifically developed for optimal performance and accuracy across any riding surface.
- Uses accelerometer for battery life on smooth steady state cruising and automatically switches to the gyroscope on rough terrain, gravel or for high RPM sprints.
- Improved cadence reliability for power measurement.
- Instantaneous start-up and transitional responsiveness for those sprinting up to 220 rpm!
- Battery life on a coin cell.
“We’re committed to disrupting every part of the cycling experience we touch,” said Phil White, President and CEO of 4iiii.
“With this update, we’ll be able to integrate features powered by our patented 3D power meter system and machine learning without decreasing long battery life and the precision for which 4iiii is known.
“In addition to these features, we also see this firmware as a way to start to treat power meters as tech platforms for cyclists. Innovations like this will allow us to further unlock a rider’s potential with simplified training tools.”
With two patents pending for new technologies developed, the PRECISION 3 firmware update 1.2.0 is now available for all PRECISION 3 owners via the 4iiii app.
