The DigiRoller II Replacement Wheel 3013 is made of high-impact plastic and hard rubber, so it is durable and able to get the job done. When using a measuring wheel, it is important to use the right wheel. The measurements will not be accurate if the wheel is the wrong size. This wheel is 12 9/16" in diameter and has a circumference of 39 3/8”, so it can only be used for the DigiRoller Plus II.
A measuring wheel is great for small areas where you can walk around to take the measurements. If something should happen to the wheel, it is a good idea to have a DigiRoller II Replacement wheel on hand, so you do not have to waste time on the job until you have another wheel delivered.
The system works well for figuring out lengths, areas, and perimeters. Even if you are working in an area that has a wall, the unit will calculate for the size of the wheel in your measurements, so you do not have to sacrifice accuracy, as long as you use the proper DigiRoller II Replacement Wheel.
