About Tone Probes

Telephones are a daily part of many people's lives; however, these handy devices are often prone to breaking at inconvenient times. A tone probe is certainly one useful tool to have around when it comes to fixing home telephone issues. A tone probe is used along with a tone generator to tell the user how far or close he or she is to the end of the telephone wire. This is quite useful when the end of said wire is stuck somewhere in a wall or tangled up with a mountain of other wires. The tone generator will send a sound through the wire, which the tone probe is then able to pick up and indicate where the desired wire is in relation to the probe. Many types of tone probes have an internal speaker and also come equipped with volume controls and sometimes even signal strength indicators. For your phone line repair needs, a tone probe is a device that should definitely be in your tool kit.
