Just an update for anyone who's been following my woeful tale of the HPC Electropick That Wouldn't Open Locks, I've finally managed to find SOME success, using a high throw and holding it upside-down with super light tension and a stiff wrench and basically just moving around and savaging the thing. I have not opened any tough locks, certainly nothing I've been unable to open manually, and nothing with a keyway that's at ALL restricted. But I've managed to get many of the locks I can manually pick, though not really any faster. It's something, though, I suppose.
The saga continues... I wonder if I'd have better luck with a snap pick gun.
