The Proskit MT-7071K is a comprehensive cable testing and tracing system aimed at telecommunications installers, network engineers, and cable TV technicians. The central unit measures the distance to a cable break up to 1,200 m, produces pin-to-pin cable maps with shielding status, and uses a 580/1160 Hz tone signal to trace cables over 3 km through walls, conduit, or aerial runs.

The kit ships with 8 remote units (plus the central unit, totalling 9) for simultaneous multi-outlet cable mapping. An NCV non-contact voltage detector (AC 90–1000 V) is built into the receiver for safety checks. All accessories — patch cords, alligator clips, earbuds, and a carrying case — are included.

Key Features

• Cable length measurement up to 1,200 m with ±2% accuracy (610–1,200 m range)
• Minimum detectable cable break distance: 2 m
• Cable detection via antenna: over 3 km at 580/1160 Hz
• Pin-to-pin cable mapping with shielding detection
• 8 included remote units for simultaneous multi-outlet testing
• Non-contact voltage detection: AC 90–1000 V
• Selectable units: metres, feet, yards
• Additional functions: ohmic continuity test, AC 60 V / DC 48 V line protection, phone/data line identification, auto power off, low battery indication

Product Benefits

• The 1,200 m break detection range covers virtually all in-building structured cable runs, including long horizontal and riser segments
• Eight remote units ship included — multi-outlet mapping can begin immediately without sourcing additional accessories
• Two identification tones (580 Hz and 1160 Hz) allow two separate cables to be traced simultaneously without tone confusion
• Three selectable measurement units (metres, feet, yards) make the tool suitable for international projects
• AC 60 V / DC 48 V line protection guards the instrument against inadvertent connection to live low-voltage circuits

Why You'll Love It

• All accessories are in the box — RJ45 patch cord, RJ11/12 telephone cable, alligator clips, earbud, carrying case, and user manual — so setup begins immediately on site
• The carrying case keeps the central unit, 8 remotes, and all cables organised during transit between jobs
• BNC connector support on the remote units extends the tool's usefulness to coaxial cable plants such as CCTV and cable TV installations
• The auto power-off function preserves battery life during extended cable surveys
