Hit with more accuracy with the PACT Model 1 XP Chronograph. This chronograph delivers solid reliable and accurate performance at a great price. The Model 1 XP incorporates the Glint Guard2 Bullet Detection System and includes the infrared Skyscreen System and mounting bar at no extra cost. Image The advantage of using skyscreens over the little throwaway down-range-box chronographs is that the chronograph itself sits safely next to you, where you can easily read the display and operate the controls. The Model 1 XP will display shot number and velocity when you fire and calculates the Average velocity, Extreme Spread, Standard and Average Deviation, and also recall individual shots. The infrared skyscreen system has a huge effect on both the accuracy of the chronograph, and the reliability of function. The skyscreen gives the shooter a large window to shoot through while blocking direct sunlight from striking the sensor. This Chronograph, like all of the PACT products, these are made right here in America and comes with a lifetime warranty.
