The Triplett 3375 Fox Jr. and Hound Jr. portable, compact wire and cable tracing kit for tracing non-energized, hidden wires has an inductive tracer with audio and visual signals, a tone generator with adjustable warble tone, and the two components can be used up to 12 feet apart. The tracer beeps and flashes a red light for clear indication of magnetic fields. The tone generator sends a warble tone that can be adjusted for guiding the tracer to wires. The tracer can detect a signal from the tone generator up to 12 feet away. The tracer and tone generator are each cased in acrylonitrile butadiene styrene (ABS) plastic for strength and light weight. The kit has a one year warranty, and is often used by home remodelers and in the telephone, electrical, and security industries to identify specific cables, trace their path, and find malfunctioning wires. The tone generator connects to non-energized wires with alligator clips or a wall jack using an RJ-11/RJ-45 combination plug, and has a 4” cord. The tracer has an ear jack for use with electromagnetic earphones from 8 to 2,000 Ohms, and accepts a 1/8” (3.5 mm) mini-phone plug. The tone generator and tracer dimensions each 0.8 x 1.25 x 5.8 inches (H x W x D), and each weighs approximately 1.7 oz. (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The tone generator and tracer each operate on one A23 battery (included). Wire tracers are used to locate wires in walls or underground locations. They identify circuit breakers and short or open circuits, which break electrical connections and prevent optimal electrical flow. Wire tracers are commonly used by home remodelers, and in the telephone, electrical, and video industries.
