We work with pine, but you can use any soft wood, including spruce. It's really important to look for boards that don't have too many knots, especially in the center - you don't want axes bouncing off your bullseye. The bullseye (inner red circle and unmarked 5 ring) must be 3.5” inches in diameter inside the center ring. The bullseye must be 24” inches (60.96 cm) from the bottom of the board. This should make the center of the bullseye 60″ from the floor.

Before the competition, a special target for practice throws must be made available.
