I picked this up recently. GoPole's Grenade Grip for GoPro cameras. The world's most popular action camera has spawned an entire industry around custom mounts that will allow you to mount GoPros on everything from bike handlebars to combat helmets and firearms. GoPole made its name with a very popular pole mount. This rubberized handle is handy for situations where you need to film handheld shots while keeping a good grip on your camera. I haven't really had time to test this properly but hopefully at the very least it will eliminate some of the handling noise that GoPro is notorious for.
