Mark 7 Reloading PrimerSense Low Primer Sensor for Autodrive for Dillon 650, 1050

The Mark 7 Reloading PrimerSense Low Primer Sensor adapts your Dillon Low Primer Alarm to work with the Mark 7 Autodrive so that it will actually stop the press when you are low on primers. The PrimerSense Low Primer sensor takes the guess work out of your loading operation by alerting you when you are low on primers mechanically. The Mark 7 unit already has a programmable stop due to low primers that you enable from the included tablet. When your low primer alarm activates, it will also stop the autodrive. Install this mechanical unit and you are doubly protected from running out of primers and spilling powder all over your shell plate. This unit installs in moments with the included hardware and rides underneath Dillon's audible primer sensor. When that unit goes off, PrimerSense will also be enabled and it stops the machine at the end of the stroke. You will then see a note on the tablet to refill your primer tube. A must-have for people that want full protection from running out...
