helmet
Hello Gentlemen,
The companies I work for didn't require me to use it but since my starting day in the helicopter businnes I use helmets for fly.
On first istance I used an used SPH-4 from military surplus; it performes well for max 1 hour trips, after a while hot spots showed off.
Than I got a new HGU-56 and the SPH-4 went in a box forever.
Great fit and noise attenuation with CEP and gel hearpads helps me to bear 3 hours Hems and Offshore flights flying a 412.
The field of view is a little restricted due to his tipical visors mount but I appreciate the light weight and confort of this helmet in every season.
Best regards
