Works perfectly

I used this to locate buried utility lines on my property before digging. It worked exactly as expected and the signal was clear. It saved me from hitting a gas line. Worth the investment.

Good transmitter

It's easy to use and the frequencies are useful for different applications. The battery life is decent. It would be perfect if it came with a carrying case, but the price is right.

Accurate and reliable

I'm a utility locator and this transmitter is a lifesaver. It connects to lines quickly and the signal is strong. The multiple frequencies help in different situations. I recommend it to all my colleagues.

Great value

Got this at a huge discount but it performs like a much more expensive unit. The build quality is solid and the controls are intuitive. I've used it for locating sprinkler lines and it works great.

Solid unit

It does what it's supposed to do. I've used it with my locator receiver and it always locks onto the signal quickly. The battery compartment is a bit awkward, but overall a good product.

Okay, but finicky

It works, but you have to make sure the connection to the line is solid or it won't transmit properly. I had some trouble getting a signal through painted pipes, but after cleaning the connection point, it worked.

I'm a home inspector and this helps me trace lines quickly. It's compact and durable. The instructions are clear. It does the job, though I wish it had a longer battery life.
