LCD - Customer Communication

I am perfectly fine with the old style with the lamps that indicate circuit status. However, the benefit comes from showing the not-so-qualified customer. The readout is concise - communicates quickly. If you're inspecting a job site, or old work, and need want to SHOW the customer the problem, the LCD display certainly helps.
