Staff bags are the largest class of golf bags, and are generally seen carried by caddies or other assistants to professional or high-level amateur players. Staff bags are generally the same size or larger than a cart bag, and typically feature a single shoulder strap, a large amount of storage for equipment and even spare attire, and large logo branding designed for product placement on televised events.
Positional guides encompass a wide variety of devices meant to improve a player's stance or swing. Lasers attach to the shaft of a putter and project a "putting line" onto the ground. Specialized tapes attach to the clubhead and provide clues as to how the head is hitting the ground or the ball for future correction or club adjustment. These are also illegal in tournament play, but are invaluable while practicing.
