Dolphin Tech Cave/Wreck Line Arrows Small Fluoro (5 Pack)

The Dolphin Tech Small Line Arrow Marker is fluorescent in colour, 65 mm long and 40 mm wide. They come in a pack of 5 line arrows. These line arrows are designed for cave and wreck diving to mark out the quickest direction to the closest exit whilst in an overhead environment. The uni-directional line arrow markers provide both a tactile and visual reference to indicate the direction of the closest exit.

These 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.

The fluorescent colour means they glow when a dive light hits them.
