3D Pyramid shape FireTacks® are great for trails with longs lines of sight, or with angles. The surface face of the 3D is slightly greater than 4D, so they can be seen at longer distances. Because the 3D is a pyramid, when viewed head on facing the point, they are not as bright as the 4D. Use both 3D and 4D as a "System" to mark trails.
