  • What is a Line Detector®?

    The Line Detector® is an audio feedback unit that provides either one of four 3-second verbal messages or sound effects whenever someone walking on the vinyl line steps off the line. When anyone walks the line using the Fatal Vision goggles and steps off the line, a message or sound effects like a police car siren or scream will play. Reinforce your demonstration with a message like "Buzzed Driving is Drunk Driving!" 

    New features include:

    • Ability to broadcast over public address speakers.
    • Ability to record up to 4 individual messages or sound effects up to 3 seconds each.
    • Rechargeable battery life is extended to five years.
    • Plays messages randomly.

    The Line Detector Unit consists of a speaker unit, 10-foot vinyl line, carrying case and a roll of yellow and black "walk-the-line" tape.
