I have a GoPro5 that I use for videography. I was part of a crowdsourced stabilizer project that was going to be usable with both phones and GoPros, but they dropped the GoPro support during development so they kindly refunded my money. I’d still like to find a stabilizer. I know GoPro makes their Karma Grip, but it not having a replaceable battery bothers me as do other features - like no joystick. I’d like to be able to use a boom/crane with the rig, not a huge one but maybe 10’. I know the Karma Grip can do this since they offer a separation kit. Other ones that have caught my attention are the Feiyu Tech G5 and the REMOVU S1. Does anyone here have experience with stabilized action cameras that can offer suggestions or comments?
