ALPHA 900 Search and Rescue (SAR)


Based on the design adopted by the U.K. MoD, the Gentex ALPHA 900 Search and Rescue (SAR) Helmet System is the world’s first waterproof rotary wing helmet system optimized for any search and rescue aircrew personnel conducting air-to-sea operations. The modern and lightweight design, features corrosion-resistant hardware, plus a waterproof and salt-fog resistant communications system to ensure continued performance when exposed to water and spray. Optimized for interfacing to common SAR radios and configurable for all major aircraft intercom systems, the Gentex ALPHA 900 SAR is the ideal solution for aircrew operating near water.
