Setting a New Benchmark in Maritime Safety

Daniamant, a global leader in maritime safety technology, has unveiled the AQ-4 MKII strobe light – a breakthrough designed to deliver exceptional underwater visibility for professional maritime and offshore operations. The innovation marks a significant step forward in life-saving technology, providing reliable illumination where visibility is critical.

Unlike steady light sources, the AQ-4 MKII’s powerful flashing LED strobe ensures long-range detection, particularly in low-light or night-time conditions. In emergencies, this enhanced visibility can be the difference between life and death, helping rescue teams to locate individuals swiftly in turbulent seas or darkness.

Fully certified to SOLAS, MED and USCG standards, and assigned a NATO Stock Number, the AQ-4 MKII meets the highest global safety requirements.

Trusted by Professionals Worldwide

Developed in collaboration with maritime experts, the AQ-4 MKII enhances search and rescue efficiency by increasing detection speed and accuracy. It can also be used to mark personnel, equipment or obstacles, improving safety across a wide range of operations.
