Steve is organising a charity sponsored walk to raise money for a good cause.
He has not organised an event before, and wants to run everything to his best ability, to ensure maximum safety for the participants.
Steve realises that there is the potential for the walkers to become fragmented along the route, as slower walkers are left behind.
He has decided that there should be walk organisers strategically placed at the front, middle and back of the walkers to ensure safety, should an emergency take place.
Being a brainy chap, Steve realises that instant communication would be needed in an emergency.
Therefore he uses handheld two-way radio.
