Review: Not a precision db meter, but it does what I need it to do. - I’m a fiber technician and I got this tool for two reasons: I wanted to be able to see if a fiber has traffic without unplugging it, and I wanted something that could detect 2khz tone. This product does both. I paired it with the Orientek T15M light source, which I use to generate the 2khz tone. This device always picks up the tone — the furthest distance I’ve tested so far is around 6,000ft. So I’m satisfied with that function. I compared the wand’s db readings to the db readings from my Viavi Optimeter, and the wand tends to read over or under by quite a bit… but that’s a $5,000 meter and this is a $70 wand. Bottom line: if there’s traffic on the fiber, it always detects traffic. If there’s no traffic, it always reads “Lo.” Other reviews have said that they have issues with the wand reading no traffic when the fiber does have traffic, but I have not encountered this issue in the field after 1 month of use. I would say I 100% trust this device as a live fiber identifier. Only possible quirk is that it often detects 270hz tone on fibers that do not have a tone generator hooked up to them. I cannot tell if this is a defect in the device, or if there is something on my employer’s fiber network that reads as 270hz. So, the only issue I’ve had to work around is double checking that when the wand beeps from the tone, it’s reading the 2khz from my light source and not the 270hz from the splitter. Conclusion: it does what it’s supposed to do very well for the price. If you want pinpoint precision, then you’ll have to look in the $600 - $2,000 price range for an EXFO or Jonard wand. But if you already have a good db meter and want something under $100 for detecting traffic and tone, this is your best option.
Review: Basic - Does work but feels cheap. Plastics are lower quality and the screen is hard to read in direct sunlight. Taking a photo of the reading is difficult aswell (have to tilt it around for angle). I use this for work every day and it has been working for months now. For the price this delivered what was expected. Readings vary by how hard you pull on the trigger too but not by much. Good tool to find light but not for exact readings.
