Fiber Optic Visual Fault Locator 50KM with FC/LC Adapter Kit, VFL Include Single Mode 9/125um FC Male to LC Female Connector, Fiber Light Pen for CATV Telecommunications Engineering Maintenance

I work in several areas which require checking light, finding the Z end of jumpers and connections that are not documented. This light so far has worked very well. I also try not to drop it, that seems to be a leading problem with all VFL's. So far so good.

Well made and works perfectly in broad daylight. I've used it mostly on singlemode fiber but it works fine on multimode too. The included batteries are pretty low quality, so I'd keep an eye on them. After leaving the VFL on for a couple of hours straight, the included batteries started to leak a clear fluid which I'm pretty certain is corrosive. I removed them, cleaned out the battery compartment, and installed some quality name-brand alkaline AAs.

The media could not be loaded. The Fiber Optic Visual Fault Locator works great. However, after a few uses, the laser became weak, so I decided to replace the batteries. To my surprise, one of the batteries was leaking, and corrosion had already started. If you're purchasing this product, please check the battery compartment before first use to ensure there are no issues. This seems more like a quality control issue rather than a product defect.

I’m in telecommunications and fiber pathing is a very important part of my day and this tool makes it very easy to do so.

Had over a year, works fine

When it worked it worked well. After 3 months it stopped working. I contacted GESD the manufacturer and told them that I tried new batteries and they sent me a message back and told me to replace batteries. ??? So now I will buy a different version of this. Very disappointed.Update:; Changed to 5 stars as the customer service was very good when I contacted them again. They sent me replacements next day and sent 2 of them. Wow! They are worth the effort. Buy from them without hesitation.

50km is 30.69mi this light doesn’t go 7mi.

It would be 5 stars if weren’t the switch tab. It keeps getting stuck and/or turns off, hard to set on/off. Other than that, I chose the silver in case it I dropped it it’s easy to find it compared to black. Wish it was more heavier and sturdy.
