I am selling a set of 15 3D printed line arrows / cave arrows which attach to your line for cave, scuba, or technical dives. I can also swap any number of the arrows for non-directional markers such as round line cookies (denote a specific location) or rectangular REM's (Reference Exit Markers) if you would like. I can also add your initials to them. I made the first set for a friend of mine who does a lot of cave and other technical dives. I printed these in blue at his request since that is the last color to wash out as you go deeper. I can however print these in almost any color you like including white, black, green, purple, red, brown, silver, orange, pink or even glow in the dark. One advantage to a less common color and/or adding your initials is that you will always know which arrows are yours. I print these on a textured bed so one side is slightly more reflective. It is not a huge difference, but anything that can make a small difference at depth is helpful. I can also print the version with a hole on the lower corner for putting these on a leader (as shown in picture).
When purchased, I will provide a set of 15 blue arrows unless I receive a message from the purchaser. If you would like to change the color, get the version with a hole in the lower corner, add initials, or get a mixture of REMs or line cookies, please send me a message ASAP letting me know your preference.
