It works very well to identify flaws in fiber and even to help cut and clean the fiber to prep it for quick connects. It is easy to carry (even put it directly in your pocket), easy to test on site, low battery warning, and remote detection. The design with a small pouch makes it portable; the dust-proof design keeps the optical fiber connector clean. When you need to test the continuity of the LC fiber optic patch cord, you need to use the FC male to LC female adapter to connect the LC fiber optic patch cord with the locator to test.
