Eric I agree, but I think experience makes a believer out of you. Imagine pulling off the coax to the PA to do some quick voltage tests. The DVM cable gets caught around the coax and flips it onto the circuit board. The coax shield makes contact with the A+ trace on the board and it instantly turns bright red before going up in smoke. Really a cool sight until you realize what you have done.
