This looks like one badass piece of grip equipment. I picked this up from Cinescopophillia. The Floatcam works as both a camera slider and Jib Arm. The counterweight system is killer. The Floatcam is around $4500 US. Not a ton of info on the Floatcam Website. Here is a rip from the post.
“The DollyCrane is an innovative Grip system combining the function of the camera crane, mini-jib and dolly slider. Once set up, the system can instantly change its function from dolly slider to crane and back thanks to its unique construction. The DollyCrane can be assembled quickly by just one operator using standard – heavyweight tripods.”
