Review on Locate Cables with Ease – Greenlee 501 Tracker Cable Locator by Daniel Mandal

Works great! Tired of paying $$$ to visit a local business every time they queue up - saw them use this device to fix it in about 10 minutes each time. We have 2-3 breaks a year, so this device pays for itself in about 2-3 years. The handset uses 1 9V battery. The transmitter uses 8 AA batteries. A bit like a cheap Radio Shack that looks like a construct, but hey, it works. There are 3 ways to attach the transmitter to the dog fence. The easiest way is to attach the transmitter to the o-ring clamp and place the exposed dog wire in the center of the clamp. . This induces a current in the dog wire. You can also connect one wire directly to the dog wire and ground the other; The third option is to attach the transmitter to the case, place the case next to the pawl and induce a current. I suspect I'll never use this method with a third pack, wish I'd paid for it - there may be smaller models without the pack inductor. After the batteries and O-clip around the dog wire, start walking the leash. Loud sound on the cable. None of that "zero" signal. Also the 0-10 beeper is VERY useful. Breakdown found within 1 minute, repaired and on the road. I take the batteries out of the device for storage, as I will probably only use them every 2-3 months. , and don't want this $650 device to die from alkaline battery leakage.
