Children at Sidlesham Primary School were lucky enough to head to the beach on Tuesday to try out a £4,000 state-of-the-art metal detector.
Years 2 and 3 pupils, who have been learning about Selsey and coastal erosion, visited the beach by the Selsey Coastguard Station.
They met with Selsey district councillor Roland O’Brien who handed over the expensive detector, which is used with electronically-tagged pebbles to determine the movement of the beach.
Teacher Kirsten Cookson said: “The children have been studying the beach and coastal erosion. We visited Selsey lifeboat station last week.
“Cllr O’Brien explained the detector and pebbles were used to determine the movement of the beach to help with implementing sea defences.
“Some children hid the tagged pebbles while others used the detector to find them. They absolutely loved it.”
