Hand Deeps is an area of the English Channel located 8nmi south-west of Rame Head, Cornwall and 3.5nmi north-west of the Eddystone. The name comes from the five pinnacles there which rise from the surrounding sea bed depth of 55 metres to depth between 7 and 19 metres from the surface. The pinnacles are within a rectangle about 1nmi north-south and 0.5nmi west-east.[1]
The central pinnacle rises from more than 40 metres to 7 metres. Its sea anemone-covered walls and frequent good visibility make it a popular dive site.[2]
