SkySystems USA has released a Service Bulletin on its Quick Release handle. The Quick Release is a cutaway system for chincups and the Vapor Narrow and Vapor Wes Pro helmets.
According to the service bulletin, the company found a weakness in the handles manufactured from January 1, 2009 to April 30, 2010. Those with affected handles can return them to SkySystems for a new replacement handle at no charge.
An Instructor at Skydive The Farm recently installed the Gath Altimeter Bracket to his Retractable Visor Gath, and found the process a bit tedious. He also discovered the bracket is not a "practical" mount for someone who wants to move an audible frequently from a couple of different helmets as it involves unscrewing part of the mount for removing the audible.
So he tried installing the audible on the inside of the helmet by removing part of the Gath padding and securing the audible with Velcro.
