The Miller KM77 Unified Air-Mated Diving Helmet is a state-of-the-art piece of equipment designed for professional and recreational divers seeking unparalleled comfort, durability, and optimum performance. It is a full-face, air-supplied helmet, engineered to meet the stringent standards of modern diving conditions.
The exterior shell of the KM77 is crafted from high-strength, corrosion-resistant material, providing exceptional resistance to the tough marine environment. This robust design protects the wearer's head and neck from external impacts while ensuring a secure fit. The helmet is available in various sizes to cater to different diver head sizes, allowing for an optimal seal that helps prevent water leakage.
The most striking feature of the Miller KM77 is its patented Unified Air-Mated (UAM) system. This innovative design merges the helmet and the weight system into a single, streamlined unit, making jaw joints, neck straps, and silicone masks a thing of the past. The UAM system includes an integrally-molded, low-profile crown-mounted weight system and a top-mounted exhaust port. This design significantly reduces drag and enhances diver mobility, making it an excellent choice for underwater exploration and deep-sea dives.
The visor of the Miller KM77 helmet is crafted from tempered glass, providing exceptional clarity and resistance to impacts, scratches, and abrasions. A replaceable, optically pure optical glass pane further enhances the wearer's field of view, ensuring maximum visual awareness when navigating complex underwater environments.
Inside the helmet, a comfortable, ergonomically designed headpad and neck ring create a snug fit while minimizing temperature and pressure differences between the helmet and the surrounding water. This arrangement significantly reduces the risk of barotrauma, a common issue related to high-pressure changes.
Moreover, the Miller KM77 is equipped with an easy-to-use, balanced, retrievable press-to-exhaust (PTE) valve mechanism. This feature enables divers to easily control the exhaust bubble size and shape while maintaining a consistent buoyancy level. Additionally, the helmet accommodates a variety of accessories, such as communications systems, lighting, and other specialized tools, ensuring unmatched versatility for various diving applications.
Reinforcing its commitment to safety and exceptional performance, the Miller KM77 Unified Air-Mated Diving Helmet meets or exceeds all relevant industry standards and certifications, including the American Society of Mechanical Engineers (ASME) B16.42. This helmet is the ultimate companion for professional and recreational divers who seek unmatched comfort, durability, and functionality in one high-performance package.
