Live Optical Fiber Identifier with Wave Respond 800-1700nm Built in 10mw VFL and Optical Power Meter OPM Functions FTTH Tool (YD-3309D)

Good but not so accurate

Love this thing. Saves my butt daily.

I've used alot of traffic meters and for the money, it's doesn't get any better than this! Also would be a great back up. Shows traffic direction, and strength! I've bought 2.

Great price for A much used tool when working with fiber optics

First off, it's a traffic identifier not a power meter, so it serves its purpose. If you are looking for an accurate reading not affected by ambient light splice on a tail and get yourself a meter. Otherwise, it's great. It picks up tone and they even threw in a vfl on the end, so overall good deal.
