Recognising the need to develop the three referee decision signalling system, beyond hand signs for use at events, WSF has standardized a WSF Three Referee Decision Card.
Each decision spoke has the decision identified by letter and colour and can be clearly seen by the central referee; and importantly, not by the competing players. The cards in various forms are already in use in some places, but now referees everywhere can do so, and not by making cards at home!
PRICE (including postage) per set of 3 Referee Cards:
For 1 – 3 sets: US$35.00 per set
For 4 – 9 sets: US$31.50 per set
For 10+ sets: US$29.75 per set
