Customer comment:
"I have used the Brunton digital map measurer and the Scalex map wheel and there is no real comparison. As an engineer and an amateur cartographer I was looking for a professional grade digital map measuring tool and I have tried everything that I could find. The Brunton is OK but is more like a toy with too many features like a light, compass and calculator that are to small to be of any real value. I also had dependability issues with the Brunton. In fact I always had two of them on hand because out in the field I could not trust them. The Scalex is a few dollars more but it is well worth the extra cost."

Specially designed for the Map Wheel and made of high impact hard plastic, this rugged case provides the excellent protection for the Map Wheel. The case can also hold an extra set of batteries.
