Skate Skull is a thrash-proof skateboard mount for GoPro Hero 3/3+ & 4. Tough magnesium-alloy protects GoPro, even when mounted underneath your deck.
I came up with it when I wanted to get the underneath-the skateboard angle in the video below (skater Nick Sommer uses the prototype).
We will be launching a Kickstarter campaign in the very near future (check back for updates)! And check out Skate Skull in full-fledged action in the skate-film I directed below.
