Products JLC's Products by Dave Holbrook Touch-Free Tester Before you start fiddling around with old electrical wiring, it's wise to make sure there's nothing "current" about it at all. Unlike many testing devices, which require unsafe contact with bare leads or terminals to identify a live wire, the Circuit Alert inductive voltage tester has a flashing red light and emits a noisy chirp when it gets within a few inches of AC voltage. No contact is necessary to get a reading, taking the nerve-jangling anxiety out of safety checks. The shirt-pocket-sized tester costs $10. Contact: Gardner Bender, 6100 N.
