The Firefly Mk2 ArcMarker is a lightweight, durable solution for clearly marking arcs-of-fire, trenches, hazards, or safe lanes—day or night. Designed for tactical flexibility, each unit features a green trigalight® GTLS (3x15mm) set inside a recessed slot to protect visibility and maintain operational security. No batteries, charging, or ambient light required.
A high-visibility yellow panel provides enhanced visibility during daylight and dusk, while the glow from the tritium vial becomes fully effective in low-light or nighttime scenarios. The marker’s shrouded slot can also be partially taped to adjust brightness output for different tactical conditions.
Each ArcMarker includes an integrated hook for rapid deployment and secure placement. Built for reliability, these markers function in all weather and temperature extremes for 10+ years of continuous use.
