Mark 7 Powder Check Alarm Install and Overview

Compatible with almost any manual single stage or progressive press
The Mark 7® Powder Check Alarm will sound an audible alarm if a grossly incorrect powder level is detected inside the case. A must-have for people who want full confidence that every round produced has powder. Includes inserts for both pistol and rifle applications.

Thanks. I have not figured this out yet. This will be very helpful.
