## Overview

The Triplett Fox & Hound 3399 is a professional-grade wire and cable tracing kit featuring a multi-tone Fox 2 generator and a sensitive Hound 3 probe with adjustable sensitivity and LED lighting. Designed for quick identification of various cables including LAN, telephone, and alarm wires, it offers TrueTrace technology for precise cable pair identification, audible and visual continuity tests, and robust overload protection. Lightweight and portable, this kit comes complete with multiple probe tips, headphones, and a weatherproof case, making it an indispensable tool for electricians and network professionals who demand accuracy and reliability in challenging environments.

## Description

The Triplett Fox & Hound (3399) wire tracing kit consists of a versatile Fox 2 Tone Generator (Toner) and a high-performance Hound 3 Inductive Amplifier (Probe). Constructed with high-quality materials, this wire tracing kit is lightweight and easy to use. The portable design allows you to trace wires whenever needed. The Fox 2 is a battery operated handheld multi-function Toner that generates multiple tones (Pulse or Warble), performs some basic telephone line tests (loop mA, line polarity, and ringing voltage), provides a visual and audible continuity test, and integrates Triplett's own TrueTrace and TripLatch tests while providing overload protection up to 120 VAC. The Hound 3 is a battery operated handheld lightweight Probe, with a thumbwheel sensitivity control and signal strength indicator LED. It improves on previous designs with built-in LED headlights to illuminate dark areas and reduce fluorescent light noise, a bandpass filter to suppress 60Hz and unwanted high frequencies, an earphone jack for noisy or quiet work areas, and an easy access battery cover. Find non-energized wires in walls, ceilings, and floors. Inductive tracer with two probes indicates magnetic fields with audio and visual signals. This kit includes Fox 2, Hound 3, RJ-11 to RJ-45 adapter, plastic duck bill, metal duck bill, headphones, and a sturdy weatherproof carry case. Founded in 1904, U.S.-based Triplett Test Equipment continues to be on the leading edge of specialized testers. Whether supplying vital test equipment to the U.S. Signal Corps during WWII, or providing the railroad industry with essential testers to ensure the safety of their crews and the public, Triplett prides itself on developing innovative, reliable, and durable test equipment that also won't break the bank

Review: Could not get a reliable result after many attempts. Waste of money.
Review: If you are looking for a product that was designed by an Engineer instead of a Marketeer, and with a manual that is written by an Engineer rather than a Technical Writer, then this is it! To be sure, it does have its flaws: The manual is the size of a credit card, with 62 pages of tiny text - I read the PDF on the web instead. The plastic housing lacks the finer fit and finish of more modern products. And, the spaces for the 9V batteries are cramped, making it very difficult to close the covers without a bulge remaining. I also have the $80 Extech 40180, and this product is in quite a different class, with the following additional features: 1. It is provided with a conductive metal probe tip, in addition to the insulated plastic tip. 2. Probe has a signal strength LED, in addition to the speaker / headphone jack. 3. Probe also acts as flashlight, allowing probing in dark spaces without having to turn on noisy fluorescent lights. 4. The injector box has a speaker, in addition to the speaker which is present in the probe. 5. Continuity test has an Audible Tone mode, in addition to Lit LED mode. 6. Tracer tone can be changed between Warble and Pulse without having to open case. 7. TrueTrace feature allows detecting which pair of wires signal is injected in to, by shorting at far end and listening for a change in the pulse rate. 8. It is designed to survive accidental connection across 120 Vac. 9. Injector can be connected to the base-station of a cordless phone, to wirelessly send its test tone to the phone's headsets. This allows you to use the TrueTrace capability at a distant location, even if the probe would not pick up an adequate signal, or would be overwhelmed by 60 Hz related noise. (Though not mentioned in its manual, the Extech can also drive the base-station of a cordless phone, however, without the TrueTrace feature, this is not of much use.) Jumpers inside injector's case also allow: 1. Disable speaker. 2. Disable TrueTrace. 3. Change tone to a higher pitch. 4. Change Warble tone to Continuous tone (The Extech does have a slide switch inside the case to do this). The manual is very clearly written, by someone with a deep understanding and considerable experience in using this product under a variety of difficult test conditions. It would be the envy of Hewlett Packard, which was once known for its excellent user manuals! Note, though, if you are not technically inclined you may find the manual overwhelming, and may prefer the Extech's 4-page manual instead.

*by M***N on 19 March 2016*

Bought this to trace dead 120V AC branch in mid-century built house. Worked as expected and the sensitivity control allowed tracing of wiring embedded in walls and ceilings. Took about 30 minutes to locate the break. IMPORTANT!!! If you are tracing household AC wiring make CERTAIN the breaker for the dead circuit is switched off before connecting the fox device. If you have an intermittent break and you jiggle wires while tracing them you could apply full 120 or 240V AC to the fox, which will destroy it. The supplied case is a bit too small making it difficult to get the fox and its wiring in so you can close the velcroed flap.
