Divers have begun a serach in Donegal for what they believe could be some of the worlds rarest golf balls.
The gutta percha balls they are searching for once belonged to golfing legend Tom Morris, who won the British Open four times.
It's believed that Tom Morris drove up to 20 golf balls into Lough Salt while he was designing the nearby Rosapenna golf course in 1891.
The dive team started searching the lake last month.
And diver Gus O Driscoll explained to us that they are no ordinary golf balls.....
