On-field timing of the 25-second ready-for-play
and 60-second time-out periods is simple and accurate with these innovative
products. The original Model 1100 Ready Ref introduced in 1979 allows football
referees and judges to concentrate on their responsibilities without being
distracted by checking their wristwatch. The new Model 1200 Wireless Field Clocks allow game officials to control the 25-second clocks directly.
