## Description

Komshine KFI-40 Optical Fiber Traffic Identifier Fiber Detector with V-F-L Function 800-1700nm + LED Display: desertcart.com: Industrial & Scientific

Review: Decent Identifier - Fiber identifier and direction indicator checked out fine, tested in both directions. VFL and LED worked also. Easy to grip and operate the trigger for testing. No complaints so far.
Review: Not all options worked. - I only needed it to identify active fibers. But I thought the flash light and the red identifier light were added bonuses. However those last two options did not work. I will use it for my original need but I am unhappy with the overall product.
