He lost the semi-final 2–5 to reigning BDO World Champion, Raymond van Barneveld, three of those sets on deciding legs.

He also reached the semi-final of the BDO's other major tournament, the Winmau World Masters in 2000, losing to the eventual champion, John Walton.

Mason hit the perfect 9 dart game in the last 32 stage of the Winmau World Masters, watched by good friend Bobby George, who said "it was OK apart from the treble 19 wasn't quite in the middle".

Mason lost in the first round of the 2002 PDC World Championship to Dave Askew, but reached the quarter-finals in 2003 – losing to eventual champion, John Part.

Mason has reached the quarter-finals in a few other PDC events, including the 2005 UK Open, the 2006 Las Vegas Desert Classic, and the 2006 World Matchplay.

On 14 April 2003, Mason and two friends Mark and Simon Gibson, were found guilty of aggravated burglary with intent to cause grievous bodily harm.

The attack was sparked by a Yorkshire terrier dog named Doris which Mark Gibson had bought for Harley's fiancée Jane Graham while they were having a relationship some years earlier and had been "hostile" towards her new boyfriends.
