3 Star Inc ADVTP2 Coaxial Cable Ringer Toner Tester
Tones out cables by inserting a DC current into a coaxial cable at one end and detects that cable from others in a remote location by attaching the audio toning device to the other end.
Note: This is ADVTP2 is LOUD!!! It uses one 23A (12 volt) battery. I use the TSTL-3A from HOLLAND every day, and I was surprised to see the same features with this one, just a bit louder, which is handy Apartment Complexes and MDU's. In addition to the Audio Que, the LED lighting up on the Head at the other end can clue you partner that it's time to move to the next cable. Just make sure you put the battery in right! This is an inexpensive alternative for companies that need to equip their Cable Technicians with an inexpensive means to save time (money!) when churn sees many Disco's and Installs.
