The LANSeeker™ is a fast, rugged cable tester and tone generator in one unit. It displays cable test results using LED indicators on the main and remote unit. An easy-to-use professional grade tool, the LANSeeker is a must have for residential and commercial cable installers. When the unit senses a connection between the main and remote unit, the battery-saving auto-on feature initiates test results within 2 seconds. The tester automatically powers off within 5 seconds of the cable being disconnected. LANSeeker tests for shorts, opens, miswires, reversals, and split pairs and can display connection and fault information on a pair-by-pair basis. It also generates audio tones for use with tone tracers on all pairs.
