Visual Fault Locator 50KM 50mW Fiber Optic Cable Tester Meter VFL Red Light Pen Light Source Testers (50 KM)

Where the hell has this light been my whole career. Man whether locating faults, tracing fibers, unscrewing company facility records, this thing is a godsend. No more trying to darken the FSAI to find my light. There are no doubts in a trqy if a splice is bad or not. Hell even in a CO i just shut the lights of and can find my f1 way to quickly. After looking and finding this i realized my company provided crap was only 10km. Will never leqve home withouth this. Been in use daily for 6 months now and no issue. The top dpes unscrew and though my light was gping bad, but once i tightened the adapter back down it worked like new. Look at angles for this light, ypu will see a dark spot fpr the rest of the day if you look directly into a eye in a serving terminal.

Works great. Longest I have tried is about 10 miles but it was so bright I could see it flashing 25 ft up in the air at duskThis laser will mess with a fusion splicer so you have to remove to splice both single or mass fusion.

Horrible wont last past 3 months. I reached out to company and they wont replace or do anything.

We had to check the fiber from one building to another. The building was over 1 mile away and the light was visible through the dust cap. I am waiting to see how far it will go.

Works great on quick checks on long fiber runs even in a dirty dusty environment. Makes it easy to identify working pairs of fiber.

I ordered it a while ago, it is excellent, but then I bought 5 more, 3 began to dimly shine in the next 7 days. quality is fickle

Red light is very powerful.

Light was great at first. Far exceeded my expectations. Really bright. Then today used one fiber worked great as usual, cut off and moved to next fiber noticed it was really dim. Changed batteries still extremely dim, great while it lasted.
