There are two types of ball:
- Training balls: easily recognisable from their yellow colour, or white with a red circle.
- Competition balls

A golf ball comprises several layers (2, 3 and sometimes 4 layers):
1-core
2-shell
3-cover

Ball compression level: the ball compression level tells you its stiffness. There are several ball compression levels: 70, 80, 90 and 100.
You should choose your compression level to suit your swing speed: if you have a fast swing, you should choose balls with a fast compression level, and inversely for slow swings.

Number of pimples and depth: pimples help the ball's air intrusion. Their number and shape will vary depending on the ball type.

Tees:
Prefer plastic tees to extend your tee lifespan.
For teeing off, big size tees enable better striking of the ball with oversize head drivers.
