Blew $85 on a magnetic stud finder that beeps at my own hand
Grabbed it at the supply house in Reno three weeks ago thinking it would speed up my rough-ins, but it went off on my watch, my tape measure, and once on a soda can. My old $12 one with the little bubble level never lied to me, so now the fancy one lives in the truck door as a reminder. What cheap tool do you keep going back to no matter what the reps push?
