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.
