Test Equipment: Tone Hunter Signal Injection Devices

Product Details:

Wave probe over broken out wires and the one with tone can be clearly identified. We install a brand new fresh 9v battery before shipping. Try it once and your tool box will never be without one again. Priced at a fraction of original cost.
