This digital caliper measures both inside and outside diameters. That means you can use it to find out what size endcap you need for your braid and figure out what size your unlabeled stash endcaps are.
Toggle between millimeters and inches with the push of a button. The scale is 0.1mm/0.01". It's accurate to +/- 0.2mm/.0078". It's powered by one SR44 1.5v battery. The caliper comes with one battery pre-installed. Just removed the little strip of plastic to activate. It has an on/off button, but will also shut off automatically after a few minutes of rest.
