The Dolphin Tech Round Line Cookie Marker is white in colour and 5.5 cm (2 inches) in diameter. They come in a pack of 5 markers. Cookie line markers are used to mark a specific place on the line, but do not give directional information.
These non-directional marker cookies are often used by cave and wreck divers to mark reference points for divers during circuits and traverses, distinguishing lines at a 'T' intersection, or placed by each member of a team on a jump or gap line to identify who has exited should the team get separated. Non-directional markers should have some form of personal identification printed on them such as initials, or drawings.
The white and orange colours make them easy to spot.
