Jonard PT-350 Replacement Speaker for PT-300 Pocket Continuity Tester and Toner

Really strong toner .

I had a bunch of unmarked coax runs sticking out of the ground, and I needed to find out where they went and if they were OK, and this really does the trick! Excellent build quality.

I quickly located the problem. (A bad splitter) saved me a ton of time attempting to locate the problem with my multimeter. This one is a really good tool.

Broke after using it the 3rd time

Solid metal and works as advertised. Great tool!

I’ve always had one of these since I’m all around Tech and when toning or troubleshooting a single line this makes your life a lot easier. But I just got one on August 20th and it’s already broken. I’m guessing most likely the speaker but it didn’t even make it to three months. He’ll it didn’t even give me a chance to loose it, which is what happened to my previous ones. Just sucks that it didn’t even lasted at all. But good tool to have.

I have not used this a great deal since purchase but I have tested it out and it performs nicely. Build quality seems really nice too.

Small size and does the job!

Worked great right out of the box. Saved me a lot of f time and steps.

I needed to trace some coaxial lines in my house and this worked great. Plugged it into the wall jack in the living room. Took the Squeaker up into the attic and knew which line was which. This is a great basic coaxial mapping tool for the professional or the home owner.
