Karate Referee and Judge Alert System

This is the perfect training toolkit for transforming your Referees, Timekeepers, and Judges into confident, capable, and professional officials.

How it works

Alert - ATO-SHIBARAKU

When the match time reaches ATO-SHIBARAKU, the timekeeper presses Button 1, triggering an audible/vibration alert to the referee to immediately announce  ‘ATO-SHIBARAKU’ to the athletes.

Time Up – Yame

When the match time concludes, the Timekeeper presses Button 2, initiating an audible/vibration alert to the referee, prompting them to stop the match.

Stop Match - Halt the Bout

As required the Kansa or Timekeeper has the autonomy to activate the button on the Pendant Button or Button 3, initiating an audible/vibrate alert that promptly notifies the referee to halt the match.

KATA - Time Notification

Track time-related infractions, such as exceeding the maximum performance time or time wasting of more than 35 seconds. When such violations occur, the timekeeper promptly notifies the Judge(s) by pressing Button 4 initiating an audible/ vibration notification.

Benefits

Its design and configuration make it highly effective in locations with multiple Tatamis in close proximity, eliminating cross-Tatami whistle confusion during concurrent Matches.

The Referee Alert system ensures precise timing and direct communication, prompting swift and decisive action by the Referee designed to complement and align with the principles of Sport Karate rules and objectives.
