This set is similar to the CWES2-2, with the addition of a Repeater, which can be used by the referee or spectators.  
 
The Repeater contains red and green LEDs plus a buzzer, the same as the Plugin.
 
The Repeater will automatically switch off 10 minutes after the last hit. The Repeater can be manually switched off by pressing the red button.
 
The Repeater can either be hand held or kept in the storage case and mounted on the Display Stand. Being hand held, the referee can move up and down the piste with the fencers, but have clear sight of the result. Mounting the storage case on the Display Stand allows both the referee and spectators to view the result.
 
There is no limit to the number of Repeaters than can be paired to the two Plugins, so you could have a configuration comprising a Repeater at each end of the piste and one in the center.
 
The Repeater will run over 9 hours or more than 2000 hits on a single charge using a standard USB-C charger (not supplied).
