line markers are generally used on permanent guidelines to provide critical information to divers following the line. the slots and notches provided are used to wrap the line to secure the marker in place. a simple passage of the line through the enlarged area at the base of the two slots will allow the marker to slide along the line, or even fall off if brushed by a diver. to more securely fasten the marker, an extra wrap may be added at each slot. the basic function of these markers is fairly consistent internationally, but procedures may differ by region, and between teams. the protocol for placement and removal should be well understood by the members of a specific team. temporary line markers are only for the use of the team who placed them and are removed during exit to avoid littering a cave system with irrelevant and potentially confusing information.
