Gear camera stabilizer. Very well built and durable. I've been using my Glidecam HD4000 for over 3 years on and off the ski slope and its still in perfect condition. The HD4000 can carry a camera package up to 10lbs and is great for DSLRS. I've also used it with sony fs100, fs700, Canon C300, Blackmagic Cinema Camera, and Red Scarlet and it works well with all of them.
