Mark 7 Powder Check Alarm For Manual Single-Stage/Progressive Press

Mark 7's Powder Check Alarm is the perfect addition to the manual APEX10 press or other manually operated progressive presses. The Powder Check Alarm sounds an audible alarm if an incorrect powder level is detected inside the case, protecting you from double charge and no charge conditions. The sensor operates on a AAA battery (included) and sounds a loud alarm if an incorrect charge level is detected. It can be used on almost any manual operated press and includes inserts for both pistol and rifle applications.
