Trundle Wheel with Counter

This trundle wheel is a user friendly measuring device. It is convenient for school children who need an easy way to find the distance from one place to the other. The handle can be adjusted into 4 different lengths. No matter whether you are a child or an adult, the different lengths of the handle will fit your needs. The counter included with the set will conveniently calculate the distance you have moved. The material of the wheel is non-slip rubber for more accurate measurements.

You can measure the distance in two different ways. When you use the counter, make sure you set it to zero first. Move the wheel backwards until the needle points towards start. You can now move the wheel in forward direction. One revolution of the wheel equals one meter of distance travelled on the ground, and the counter will click once. The total distance can be read on the counter.
When you use the pointer, make sure you start with the arrow pointing at start. Every tme the wheel makes a complete rotation, the wheel produces an audible click. By counting the number of clicks you can calculate the disctance travelled. The end point of the arrow will show the extra centimeters.
