Why This Matters to Your Shop

Direct contact testing gives your technicians instant confirmation on live circuits—critical for safety and liability. Inductive testing eliminates the need to strip insulation or access bare conductors, reducing risk and speeding diagnostics. The break-point detection feature directly addresses a real pain point: locating damaged wire sections in complex harnesses without expensive diagnostic equipment.

Stock this tester as part of a core electrical diagnostic bundle. The battery-free design means consistent margins—no service calls delayed because a technician forgot replacements. Pair it with a vehicle battery test system for a complete electrical troubleshooting station that appeals to multi-service shops.
