This Upright Comparator Tool has been designed to work with the Comparator Kit (available separately) inserts to allow you to measure your brass cases, or complete rounds, in an easy method rather than the traditional 2-handed method with a set of callipers, which can be tricky for longer cases, or those with issues with grip. 
The Upright Comparator Tool has been designed around our digital gauge (available separately) to accurately measure your cases, complete rounds, or even just a bullet’s ogive length, to an accuracy of 0.001”.
The unique adjustable “V-plate” on the base allows you to perfectly line up your cases for ultimate concentricity.
The kit comes with a standard height adapter for the comparator kit inserts, but an “XL” adapter is also available should you wish to try this.
