Simple 3D pedometer for daily step tracking

The 3DActive A420S is a clip-on activity tracker that counts steps using a 3D tri-axis sensor. It has a 1.7 inch display and weighs 3.1 grams. No smartphone pairing or Bluetooth connection is needed, so it works straight from the package. It suits walkers of any age who want a basic step counter without setup complexity.

Check battery type and wearing preference

The device runs on a replaceable lithium metal cell rated for 12 months of use. Verify you are comfortable changing a coin cell when it depletes. Choose between the supplied clip, lanyard or simply carrying it loose in a pocket or bag. The one-size plastic housing measures 3.9116 by 11.2014 by 16.1036 centimeters.

Steady counting during long walks

The 3D sensor maintains accuracy whether the unit hangs vertically, lies flat or shifts angle throughout the day. Step totals accumulate continuously on the large digits without resetting until you press the rear button. The ABS shell and light weight of .84 ounces keep it comfortable for all-day wear over many months.

Questions about this item

What comes in the box and is anything else needed to start tracking?

The pedometer, a clip and a lanyard are included. A lithium-metal cell is already fitted, so no separate purchase is required to begin counting steps.

Which version should I choose if I only want step counting without phone pairing?

This single model has no Bluetooth or smartphone connection; it is designed solely for step tracking, so there is no alternative version to consider.

What does the 1.7 inch display show in everyday use?

The full-screen display shows your current step count in large digits that can be read at a glance while walking or standing.
