  • Cool bright
Model: Green Light - 30mW
This thing is the coolest visual fault locate I’ve ever used doesn’t go as far as the red but it’s brighter up close

  • Great fault locator
Model: Green Light - 30mW
Since every other tech I work with uses red, it makes my access port very easy to find. Being rechargeable is also a huge win.

  • Defective Right Out of the Box.
Model: Green Light - 15mW
Straight out of the box, this visual fault locator pen was defective. It would not turn on no matter what I did. I replaced the batteries, checked the contacts, and still nothing. This was an obvious quality control issue.

  • Nice tool to have!
Model: Green Light - 30mW
Gifted this to my son. He has a large collection of tools and is happy to have added this. Said he actually used it to check the fiber optics panel at his mother in laws house. Found a break in one of the cables instantly. Said the green light is bright. Fits nice in the palm of his hand. Looks and feels of great quality. Wired perfect for what he needed it for. Very reasonable priced. ... show more

  • Good Quality
Model: Green Light - 15mW
The tool performs its function effectively and is well-designed. Its exceptionally bright light makes it convenient for testing fiber optic cables.

  • Bright, but no ability to snap or screw in connectors to leave in place for tracing fiber runs
Model: Green Light - 15mW
Super bright light! The flashing mode and option for green is a game changer! The only downside is you really still can't make this an easy 1 person job to shine fiber across a path because you cannot snap or thread in the connectors and just let the unit hang.

  • Clear and accurate
