Calculated Industries Card measuring device

This device can be used for measuring distances on maps and plans. The precision wheel makes it possible to roll forwards and backwards and use it with both hands. The attached pointer indicates the exact start and stop point. The device has two integrated memories and is operated using the buttons and the display on the device. The following units of measurement can be selected: Millimetres, metres, kilometres, decimal feet, feet, decimal inches, inches, yards and square and cubic formats. You can choose between 72 scales, 33 of which are in metric and 39 in imperial units, and create six user-defined scales. The integrated counter can be used to count objects such as bolts and exits manually and automatically. If you have rolled too far, the subtraction function provides a remedy, which can also delete counted objects. The device is supplied in a protective case with operating instructions and two batteries.
