Learn Semaphore

Semaphore was developed about 200 years ago – well before the invention of the telephone, radio or Internet – and in its time this ‘revolutionary’ communication system was taken up with as much enthusiasm as texting is today.

Semaphore is a way of sending and receiving messages between two people within sight of each other. Words are spelled out by simply changing the position of a pair of hand-held flags to indicate the required letter of the alphabet.  It is still used by NATO’s land and sea forces when radio silence is essential and really good operators can send and receive text at over 30 words a minute!

 When you come to the Record Breaker Stage Show you will be given your very own flags to use so you can get involved and help us to try and set a new Semaphore sending record. Get practicing now, learn the word we are going to send 'RECORD'.
