How to use

Open or extend the handle and lock it into the operating position. Install two AAA batteries according to the polarity markings. Reset the counter to zero using the reset control, select the preferred unit (meters or inches) on the unit control, then walk the route at a steady pace while keeping the wheel in contact with the ground. Read the measured distance directly on the LCD display. After measurement, fold the handle and switch the device off to conserve battery life.

Usage recommendations

For accurate readings, ensure the wheel maintains continuous contact with the surface and avoid sudden changes in walking speed. Use on relatively even ground for best results and replace batteries when the display dims or counts become unreliable. Store the device folded and protected from moisture and extreme temperatures.
