BuzzGold wireless slammers (robust buzzers) link to your pc. Contestants hit the slammer to answer the question. A configurable lockout ensures there's no confusion over who answers first. There are no cables to trip over, and your contestants can be anywhere within a large room. A USB receiver plugged into your laptop completes the system. You can have up to thirty contestants or teams. It's even possible to run more than one quiz game within a room. Although we say 'buzzer', you can give each slammer its own individual sound. BuzzGold slammer kits are used by many different organisations to produce quizzes and quiz games for every occasion.
