The Unity Tactical SPARK is a fully sealed, ultra-compact personal identification and signaling beacon engineered for high-visibility marking in austere field environments. Encapsulated inside a flexible, waterproof silicone body, this lightweight emergency strobe can be attached directly to helmets, plate carriers, or vehicles using its integrated hook-and-loop backing. Users can intuitively press the center of the modular housing to cycle through a positive tactile click layout featuring a constant-low, constant-high, blinking strobe, and power-off sequence. The self-contained system utilizes a built-in, non-replaceable power supply that guarantees a reliable runtime of over sixty-five hours while operating under active blinking profiles. Emitting a distinct blue light signature, this low-profile marking tool can also be snapped into an optional magnetic cage to securely weave onto standard heavy-duty tactical webbing networks.
