Chris Chris' Tips
Here's what Jim Donnelly says about the PEC Electronic Edge Finder:

"For years I've been using a battery-and-light bulb edge finder, and the problem with it was that under some conditions it was difficult for enough voltage to light up the bulb enough to give you confidence about when you hit an edge.  The PEC edge finder seems to connect the edge discovery to the base of a switching transistor, because the LED turns on brightly with full confidence when you make even the slightest contact.  Sometimes electrical resistance within the milling machine prevents enough current to flow to light a bulb, but there's always enough to switch a transistor to light up the LED."
