Keeping your measurements is essential, particularly for shooters tracking their group sizes or handloaders looking for repeatable loading data. To ensure that data is preserved and can be transmitted easily, the iGaging OriginCal Digital Calipers are equipped with data-output capability. Like the company's other measurement tools, the iGaging OriginCal Digital Calipers are machined from hardened steel and feature lapped contact surfaces that ensure accurate, repeatable measurements down to 0.001 of an inch. When paired with the company's DataConnect kit, these calibers enable users to port measurement data straight to their computer, preserving measurements for future use. Every pair of iGaging OriginCal Digital Calipers are ISO-9001 certified and can measure anywhere from 0 to 6 inches in both inside and outside dimensions. The readout can provide both Imperial and metric measurements, reading in fractions of an inch or millimeters.
