Hi, i had the old style two piece d box mounted on the side of my hawkeye helmet for my pc101.
I say had because on opening, i looked between my legs and watched it hit the ground from 2 thousand feet.
I saw the outer shell of the d box spinning off to my right, it seemed to still be in tact..
When i got on the ground both the horizontal and vertical straps were still in place. Don't know what happened, wondering if it's happened too others? Never found the camera. Bought another PC101 recently, gong to try the new style D Box.
