What each marking does, and how to practise with it.

A centre line to the hole with rails either side of the putter path. You see straight away if the face or path is off.

Trains: Start line and set-up

Two pairs of pegs just wider than a ball, 30cm and 90cm ahead. Roll it through both and your start line is right.

Trains: Face control

Ball stations every metre from the hole, so you can work through 1m, 2m and 3m putts without measuring.

Trains: Holing out under pressure

A graded box past the hole. Putts that miss should finish in the ideal pace zone, 15 to 45cm past.

Trains: Pace control

A dashed circle round the hole. Long putts that finish inside it are the ones you would tap in.

Trains: Lag putting

A ruler behind the ball with short, medium and long marks. Match backswing length to distance for repeatable pace.

Trains: Rhythm and distance

Stations 8 and 16 degrees either side of centre, so you practise putts that do not start straight at the hole.

Trains: Aim from any angle

10, 5 and 2 point rings round the hole for putting games. Great for families, offices and golf days.

Trains: Competition and fun

Nine numbered ball stations zig-zagging back from the hole. Play Around the Clock: hole them in order, and a miss means trying that number again.

Trains: Holing out from every angle

A curved line from ball to hole showing the path of a breaking putt. Lift one side of the mat and practise starting the ball on the line.

Trains: Reading break

A ruler down both edges, every 10cm with the metres numbered, measured back from the hole.

Trains: Judging distance
