The product now endorsed by Collegebowl Inc. is Zeecraft Electronics. If there is interest in the Logitek or Shelty Systems Buzz-Box, I can try to arrange a discount. Write me back if either of these systems seem right for your club. System is a box with 12 or 16 thumb activated buzzers held in hand at end of long chords. System can be set for individuals or teams of 4 players each.
System is delicate, so be careful with it.
Locks out all other responses until reset. This system accommodates 8 players. A pyramid shaped light of either blue or green plastic sits in front of each player. They make a dull beep when players ring in on thumb-activated buzzers. This system is a a no frills basic kit.
