As to mounting a Nexus 9, seems like a little crafting could make this happen but an odd choice for making videos. Most folk get a camera person on the team or just put a GoPro on the helmet.

I own a dog training business and I would like to make some videos of my work. I need to be hands free in order to maintain proper technique and record video from my POV. I would like to mount a nexus 9 onto my chest with a harness or something. Can anyone recommend any products, ideas, or personal experience.
