Platinum Tools’ T129 VDV MapMaster 2.0 combines continuity testing, mapping, tone generator and length measurement functions into a single unit. Capable of identifying and mapping 19 locations at once, it measures the entire length of a cable and/or individual wire pairs. It tests voice (6 wire)/data (8 wire)/and video (coaxial) and it has an easy-to-read, extra-large seven-segment LCD screen with large icons and a tone generator with selectable tone cadence and selectable pins. The RJ (voice and data) master remote stores in the bottom of the case.
