Made from an engineering grade of PLA, our line arrows are grooved on one side to allow divers too easily differentiate then from other markers even in thick gloves.

 

These directional markers can be used on line up to 4mm thick.

 

Directional markers are known as “line arrows” in the cave diving community.   Many popular cave diving systems have permanent line arrows at regular intervals (for example, every 30 metres or 100 feet) pointing to the nearest exit.  If there is a numerical value displayed on the line arrow, it is most likely identifying the distance to the nearest exit.  In addition to providing directional reference, and depending on the local practices of the cave divers in that region, permanent arrows may be used to designate secondary passages and midpoints in the cave.
