Our polystyrene line cookies are available in white, yellow, orange and glow-in-the-dark and are slightly more than { 2 in | 5.1 cm } in diameter.

Cookies are preferred over line arrows for setting up traverses or circuits because a directional marker on the line could be misinterpreted as pointing away from the closest exit - disastrous in an emergency. They are a must at jumps, especially jumps made from points at which no permanent marker has been installed. Placed on the outbound side of the jump, they confirm the exit direction as divers return to the jump.
