MOUNTING THE BOARD

The board is sold with a clip for mounting it to the wall. On the back of the board there is a screw (at least a whole for putting a screw in should be there). This screw is placed at the center of the bull's eye and it fits in the clip. So mount the clip on the wall, at the correct throwing height. When you hang the board the screw snaps into the clip. Then fix the board with wooden chocks or cardboard.

 

THE THROWING LINE

The Throwing Line is a line on the floor you must not overstep when throwing. It can be a simple line on the floor, or a raised (wooden) bar. Such a raised bar is called an "Oche" (also known as "ockey, ocky, hockey..."). If you want to set up a decent throwing place you should implement an Oche. You will find them implemented in most better pubs and at all tournaments that have some importance. It just makes overstepping the throwing line impossible, leaving no room for dispute. To make it useful, the Oche should be about an inch high and the length should be about 2 feet or longer.

 

DARTBOARD LIGHTING

All dartboards are required to be adequately lit by a suitably positioned light fitted at each dartboard equivalent to a 100-watt spotlight. All light fittings must be fitted with screens or shades to divert direct light away from the player’s eyes when standing at the throw line.
