Two adjacent arrows facing away from each other mark a point in the cave where the diver is equidistant from two exits. Two adjacent line arrows may also mark a #34;jump #34; location in a cave when they are placed pointing toward each other; although a better method is to use a non-directional #39;Line Cookie #39;. FEATURES: Line Arrows are uni-directional markers providing both a tactile and visual reference to indicate the direction of the closest exit. 12 white markers
