The Hornady Lock-N-Load Deluxe Control Panel includes digital readout panel, wire harness, cycle counter, primer slide sensor, powder safeguard die, powder level sensor and primer level sensor. The easy-to-read digital display with multiple sensors allows you to set audible and visual alarms for primer quantity level, powder hopper level, and primer slide check. The Powder Safeguard Die checks straight-walled cartridges from .380 to 45 caliber for powder charges and physically halts the reloading stroke when a no-charge or double charge is detected. The LED panel displays the number of press strokes, and also alerts the user when a sensor detects a low primer/powder level or other issue.
