DTL now forms part of the family of trap disciplines and in number of competitors is undoubtedly the largest variant, especially in the Commonwealth countries where it is most popular.
[citation needed] The traditional DTL shooting layout is set up with 5 stands in a crescent shape 16 yards from a traphouse, which throws a random target from an oscillating trap between 0 and 22.5 degrees to either side of a center post, set 50–55 yards from the traphouse.
DTL is perhaps the 'easier' single shot to make of any clay shooting discipline, but the result is an incredibly high standard of competition.
Even a small club shoot will see almost perfect scores posted by the better shots, so concentration and mental strength are the real talents displayed by competitors.
Most governing bodies record their members scores from every registered competition and then grade the competitors into classes, similar to a golf handicap.
For major international events or Inter-County (IC) championships, teams representing each country or county may be formed.
The sport is very inclusive – a novice shooter can find themselves on a squad alongside a World Champion, his wife, grandfather and grandson competing on equal terms.
Other variations are double rise DR, single barrel SB, automatic ball trap ABT, and handicap by distance HPD.
Northern Ireland hosted their first ever DTL Home International and British Open in 2006 at Culbann C.P.C, Ballynease, County Londonderry.
There are also the Euros held each year, that will attract teams and competitors from other nations such as France, Sweden, Germany amongst many others.
Every two years, the DTL World Championships are held, alternating between the Northern and Southern Hemispheres.
