Never Lose Your Marker Again. Why you need it: As an instructor, your marker constantly gets lost in the dirt, dropped, or misplaced. This cap from PE3D keeps your primary charting tool securely around your neck for quick, hassle-free, one-handed access while taping and calling targets. 1. How does it stay attached to me? Dog Tag Style Chain: Comes with a standard, durable metal ball-chain necklace that hangs comfortably over your shirt, range shirt, or body armor without interfering with your gear. 2. Will the marker fall out while I'm moving? Secure Friction Fit: Precision-molded to hold the marker body tightly. It will not shake loose while you are running drills or bending over, yet it allows you to pull the marker free instantly with one hand. 3. What markers does it fit? Standard Utility Fit: Engineered to fit the most popular, standard-sized permanent markers (like standard fine-point Sharpies) used on the range. (Marker not included).
