Who this armband is for

The Fitcent CL830 optical heart-rate monitor straps onto the upper arm, forearm or triceps and streams live beats-per-minute, training zones and calorie data to phones, tablets, GPS watches or bike computers. It serves runners, cyclists, indoor-cycling fans and general fitness users who want wrist-free tracking without a chest strap.

Replaces a chest strap when comfort matters

The soft, stretchy, washable band adjusts from 18 to 40 cm and weighs far less than a traditional elastic chest band, so it stays comfortable during long sessions. Dual Bluetooth 5.0 and ANT+ radios let it connect simultaneously to a training app and a bike computer, a combination a single-protocol strap cannot manage. Battery life reaches 60 hours per charge, so weekly recharging replaces frequent coin-cell swaps.

Check your setup before ordering

Verify your phone runs iOS on iPhone 4S or later, or Android 4.3 or newer, and that your chosen fitness app appears on the 200-plus supported list such as Zwift, Peloton, Wahoo Fitness or Polar Beat. The sensor carries an IP67 rating for sweat, rain and shower exposure but is not rated for swimming. Remember to peel the protective film off the optical window before the first pairing, and wear the band to wake the sensor for Bluetooth discovery.

Questions about this item

What arm circumference range does the adjustable strap cover?

The strap adjusts from 18 cm to 40 cm and can be worn on the upper forearm, biceps or triceps.

How is the sensor paired and what common step is missed?

The monitor must be worn to activate, then paired via Bluetooth 5.0 or ANT+; a frequent mistake is forgetting to remove the protective film on the sensor before the first use.

How long does the rechargeable battery last and how is it replenished?

The lithium-polymer cell delivers up to 60 hours per charge and refills in about 1.5 hours until the LED shows solid green.
