The Amprobe TIC 300 PRO High Energy Tic Tracer is a rugged and reliable non-contact voltage detection instrument ideal for utility, industrial, and mine safety applications. It warns against dangerous voltages in low and medium voltage applications up to 122kV without contacting the energized conductor .

The TIC 300 PRO features two operating ranges. The low voltage setting detects 30 to 1500V AC for checking breaker panels, breakers, power outlets, and wiring. The high voltage setting (requiring the TIC 410A Hot Stick accessory) detects 1500 to 122,000V AC for transmission lines, power distribution equipment, down power lines, fuses, and load break connectors .

Detection distance varies with voltage: in low range, distance ranges from 2.7 inches at 30V to 7 feet 9 inches at 1500V. In high range with the hot stick, distance ranges from 1 foot 2 inches at 1.5kV to 22 feet at 122kV. The unit provides both visual and audible voltage indication to alert the operator of live conductors .

A self-test function verifies that the tester works properly before each use. The rugged design is built for demanding field environments, making it suitable for utility workers, linemen, and industrial electricians who need to verify voltage presence on high-energy systems before beginning work .
