TEMPO Communications 521A Irrigation Sprinkler Valve Locator Tool | Irrigation Wire Tracer, Underground Wire Locator (Professional Grade)

Get the 2025 upgraded version. This thing is amazing; there is a learning curve to interpret the beeping, but once you get it figured out, it’s a breeze to use. I found 15 missing valves in a couple hours (40 acre property). This saved me a ton of money and time; highly recommended!

This wire locator and underground valve finder exceeded my expectations. It is very accurate at detecting buried wires and valves, even at significant depths. The device is easy to set up and use, making it perfect for both professionals and DIY projects. It saved me a lot of time locating underground systems without digging blindly. The build quality feels durable, and the instructions were clear. Highly recommended for anyone needing reliable underground detection!

Good product

So I had my doubts about getting this unit. I had always used a similar (albeit smaller) unit that was made by one of tempos competitors, and I always heard mixed things about tempo from other irrigation contractors that use them regularly.. but this particular issue I'm having is a deal breaker.So the terminals (+, -) in the battery compartment look like someone went in there and a single loop of stripped 26awg solid core wire and called it a day. I do a lot of electrical engineering work in my free time so I figured "hey, no huge issue.... I can see that's not the best way to do that, but I'll make due, all they have to do is contact right? so maybe just wiggle them around till it powers up..."Well after about 5 minutes I get an intermittent signal. Later that day I needed to use the unit again- same thing. Keep in mind this is a job that's often done soaking wet, water getting on everything during the most inopportune times. I don't have the time nor patience to bust out a Philips and roll D batteries around like slot machines hoping the thing will work.Look I hardly ever review anything, i don't know if I've ever had this bad of an experience and shared it though. It wouldn't be so bad if it wasn't such an integral part of the machine's function. Worst part about all of this is there's actually a notecard tempo includes with the instructions (printed separately in the box) that basically says to "try wiggling the batteries around"So this is a known problem and they still let me spend $700 on it. amazon wont let me do a return since I was a few days late. please help me tempo communications. I mean do you guys really want me to go in here fix it myself?

It super. works very well

I gave it 4 stars instead of 5 because it DID NOT come with the batteries promised in the description, and the D-cell battery compartment makes it difficult to properly install the batteries. Once the batteries are installed, it works great. I found two valves (one had a bad solenoid) within two minutes, one of which was buried 8 inches underground and I would have never found it by probing into the ground. The instructions are simple but accurate, the unit did exactly what it was supposed to do. It’s light weight, and the ground stake and case are sturdy.

Time saver

This worked great. Hooked it on to a 230 foot steel fish tape and was able to locate the missing pipe line. Saved me a lot of time and money! Also works great for sprinkler control wire.
