Tools and Hardware Reviews of Gardner Bender GVD-3504A Circuit Alert Non-Contact Voltage TesterCustomer Review: Avoid a "Shocking" Experience Summary: 5 Stars
I purchased my GB Instruments' "Circuit Alert" at my local home improvement center and have found it to be a reliable tool. I own this tool and a Harbor Freight "Cen-Tech, Non-contact Voltage Detector". Both tools perform acceptably, but I like the slim design and slightly sturdier feel of the Circuit Alert. The Circuit Alert is approximately 5-3/8"L x 9/16"W x 3/4"H (including the pocket clip). The clip acts as a momentary switch and is used to activate the detector. Some reviewers have indicated that they do not like the clip switch but I find the design a positive element as you cannot forget that it is on and drain the batteries. The detector will blink once and make a single chirp when first activated to let you know that it's functioning--unlike the Cen-Tech detector, which requires you to test it on a live circuit first. (Testing it on a live circuit probably isn't a bad idea, regardless of the detector.) The GB runs on two 1.5v LR44 button cell batteries and I store my detector with a thin piece of cardboard under the clip to prevent it from switching on accidentally as the result of bumping against other tools in my toolbox. The detector is Underwriters Laboratories marked and is rated for detecting voltages from 50 to 600 VAC. Mine detects 110 VAC on 14-2 at a distance of 2" (compared to the 1/4" to 1/2" using the Cen-Tech tool and the Cen-Tech has to be on the hot side of the jacket). The detector does seem to produce false chirps near static electricity, as mine will chirp rubbing it against a knit sweater. As a DIY'er, I don't use this tool very often but they are definitely much more convenient than checking to see if a wire is live using a multimeter. It's a tool worth adding to your collection, even if all you do is replace an electrical outlet or switch now and then.
Description of Gardner Bender GVD-3504A Circuit Alert Non-Contact Voltage Tester"CIRCUIT ALERT TM NON CONTACT VOLTAGE DETECTORIndicates the presence of AC voltage from 50-600V. Visual (flashing) and audible (beeping) indicators signal presence of voltage, by pressing pocket clip. Built in safe test feature assures batteries are operating properly. Compact design fits in shirt pocket. Operates from 2-LR44 1.5 volt batteries (included) Patented." The GB Circuit Alert Non-Contact Voltage Tester tests for the presence of live AC Voltage from 50-600 Volts. Visual (flashing) and audible (beeping) indicators signal the presence of voltage by simply pressing the built-in pocket clip. The tester also features a built-in "safe test" feature that assures the batteries are operating properly. With its compact design--easily fitting in a shirt or pants pocket--the tester is perfect for checking to see if voltage is present or to verify if power is turned off before working on a circuit. The tester comes with batteries and a 1-year limited manufacturer's warranty.
