These little inexpensive HD action cams are excellent and I use them on my helmet and bird feeder etc however I don't know how you guys are mounting them for your MD videos. From the typical MD POV on YT I'm guessing ARM?
I have seen a guy that posts youtube MD videos .He mounts his
Mobius Cam on his shoulder and does very well with it.
Some other guy added a laser pointer to it,so you can aim the camera
at the right spot anytime. I hope I could help you with this tip.
