Inconsistency

It works.

Worked as advertised. Simple and easy to use

I work in the telecommunications industry and I have used all sorts or line identification tools and this mapper is solid and at a great price! It just works!

Used for mapping and testing for which of a dual cable radio is for the the new single cable. Very noticeable if you have a short. Battery has been going for six months after daily use. Do wish you could turn the mappers around and have a male end but thats just me.

I used it to find coax cable connections

thks

I used this at my house and was only able to trace 2 of my 5 coax outlets. On 3 of them it didnt work at all. Perhaps this is because theres a splitter or something in the wall, but either way I was very disappointed that it didnt work. Fortunately, I just played a guessing game and correctly figured out which wires went to which of those 3 outlets, but that was with no help from this tester. Waste of money to me. Update: I originally gave this product one star, but Im now changing it to 3 stars. I talked to a Verizon tech, and he said these types of testers wont work if theres a splitter involved. I cant confirm it, but my guess is that there is a splitter in my walls somewhere. I wont punish this product with a one star review if its not the products fault. Im not giving it 5 stars either. In the end, it didnt serve my purpose, and Im out twenty-eight bucks. I could send it back, but its more trouble than its worth, so Ill just keep it for a day in the future. The one coax outlet that did work worked very well, so I guess its not all bad.

Great tool

Easy use, functions as expected and it was less than the retail price. I was able to trace and repair a problem with the coax behind our walls caused by a bad install previously.
