Replacement NMP Sensor Drop Target Board Williams System 3-6A

$24.98$93.48 CAD


Here is a all in one replacement drop target sensor board for the 17 notorious Williams System 3-6A titles that have the finicky Horseshoe slide drop register system.

This new NMP board(s) used a magnetic sensor to record the targets drop.

No more dirty contacts, bent or broken horseshoe points, just reliability!

If your going to add this system I would suggest to fully remove, disassemble, and clean your existing drop target assemblies.

The magnet(s) are included, and glue into the molded cup on the back of the drop target. (see gallery)

Instructions with game specific wiring diagrams are included.
