## Description

Product description

Review: This really works on sprinkler control valve and connecting wire to it from controller. - Best money I spent in a while. I had a buried 20 year old sprinkler valve about a foot underground for the control wire. My irrigation guy used a $1000 locator, and had zero luck finding the valve. Under about 6 inches of grass/mulching accumulation, etc. As a last resort, I pulled this out of the desertcart box and hooked it up. Had to try a few different settings, but found the best for me to be the red wire to the control valve wire, and the black wire to an earth ground on the electrical panel..not stuck in the ground with a screwdriver, etc. Then, playing around with the control on the sender I found a position where I got good clear tone, no static, and a NULL when passing over the wire, which I knew at least where it was starting at the control box where the wires went into the ground. Then I clearly followed it about 100 feet in the yard, getting clean tone-null-clean tone. Either side of clean tone of course was nothing/quiet. So I guess it was quiet-tone-null (nothing)-tone-quiet. MUST look for a null this way...NOT the loudest. If no null, you are not over wire. And no static way off wire.Manual does not address this. Anyway, went directly to the box and lost null if past it.Hit it first time with the diving rod. Dead solid perfect. This thing is great, but have to know how to use it I guess by trial and error. Once you do it, and get moving, easy to find exact final box location by the sound changes there at the box. Kind of hard to explain but the probe was directly over the box where I had the guy test probe. Bingo. And I moved pretty fast following the wire swinging the probe back a forth. And the null is pretty precise so do not swing past it side to side. You will get the feel. I did. This is totally true. Love this as saved me a fortune. Now.....make a drawing and store somewhere as to where the boxes are!!!
Review: Perfect for finding the dog fence break - Worked like a charm! This is a radio transmitter and receiver. The transmitter connects to the fence wire, and the receiver is an antenna that you wave over the wire. If the wire isn't broken, there's a radio signal for the receiver to pick up and it makes a tone. When you find the spot with no signal, that's the broken spot. Simple and quick. You disconnect the wires from your fence transmitter. Select one of the wires and connect the red alligator clip to it, and connect the black alligator clip to ground (you might need to stick a metal spike in the ground to clip to). Turn on the transmitter and there's a "volume" dial on the side. The transmitter turns the wire into a broadcast antenna. I cranked the volume up better than halfway, which was probably more than necessary. Turn on the receiver and let the cord dangle. There's a "volume" knob on the side for sensitivity. Let the receiver cord and receiver (the "plumb bob) wave over the wire and you'll hear a tone. The tone stops when the receiver is DIRECTLY OVER the wire. That's how you know exactly where the wire is. Let the plumb bob swing and listen to the tone as you walk around the perimeter of the yard. When the tone goes away COMPLETELY, you know you're past the break. A little bit of walking and swinging and it's a piece of cake to find the broken end of the wire within a few inches. It took longer to hook everything up than it did to find the break. Well worth the $$ for a fraction of the price of the name brand pet fence break detector.

### ⭐⭐⭐⭐ Does the trick!
*by C***R on June 30, 2020*

A fraction of the price of similar tools, and WAY cheaper than hiring someone to come out. There was an dog invisible fence installed on our property when we bought the house, but when I bought the collar and control panel I discovered there was a break in the line. I bought this unit to attempt to find the break. At first I was having a hard time trying to actually "trace" the wire until I realized all I had to do was swing the pendulum left and right while walking the direction of the fence- listening for the beep as the pendulum crossed over the wire. When it stopped beeping, I put marker flag to dig there. Then, I went back to the starting point and hooked the unit up to the other wire and walked the opposite direction until the beep stopped again. I ended up replacing 2 sections of wire about 20' long each.. used waterproof wire nuts with grease caps on each repair and had the fence working in a few short hours.
