More Stability = Better Readings
You know the deal — your PulseSensor is incredibly sensitive, which is usually a good thing. But sometimes a minor movement can throw your data into chaos. The Stabilizer Ring is a knuckle-sized, custom-fit piece that elevates your pulse readings from good to great by minimizing motion artifacts.
Comfort, Quality, and Free Fingertips
The Stabilizer Ring enhances user comfort for both short-term and long-term readings. It also expands your freedom of movement while wearing the sensor. You can move more naturally without compromising the sensor's accuracy. Best of all, you can wear it like a ring and still be free to code, craft, and create with your fingertips.
How It Works
The PulseSensor itself snaps into place on the ring's cut-out. Then, use the Velcro Finger Strap from your PulseSensor Kit to secure it for a sturdy fit.
