The design of the Skyscreen has a huge effect on both the accuracy of the chronograph and the reliability of its function. Gives the shooter as large a window as possible to shoot through, while blocking direct sunlight from striking the sensor. The white piece at the top of the triangle defuses the light and acts like an overcast - providing a consistent bright high contrast background to spot the bullet against.
The Mk7 Skyscreen contains spring-loaded detents which precisely locate them 18” apart when slid onto the custom mounting bar. This can be set on a bench or mounted on any standard camera tripod. Internal optics enhance the sensitivity of the detectors as well as increase accuracy.
For indoor use, or a more permanent range set up, the M7 IR SkyScreens are the way to go. Rather than using the ambient sunlight for illumination, each Skyscreen contains an IR illuminator which is focused into a fan-shaped beam and projected up against a retro-reflector affixed to the underside of the white diffuser screen. This provides absolutely consistent illumination and extremely reliable triggering.
