HP, you know the guys who think if they buy the $2000 set of clubs or $500 cue stick, it'll improve their game

Having good reference points and rulers that you can take "square readings" with is all you need. My Robart meter didn't work last time I got it out, so I tossed it. The most use I ever got out of it was to check the accuracy of a Goldberg Ultimate Bipe...but I still double checked the readings with a ruler off the work table.
