I've done it, but there are lots of challenges.
First challenge is getting it mounted. I went with Wilcox bridge, and then use a Keymod rail and a
PVS 15 adapter. You need something to get it far enough away from your face as the mount location pushes it too far back. At least this is the case with the g24 and wilcox bridge.
Second Challenge is weight: You will need a ton of counter-weight and it helps if you can stack it more to one side in the back as although the Hogster is super light for a scope/handheld, it is still heavy for a helmet. I used the largest battery pack I could fit in TNVC Mohawk, and then added magnets for weights as well.
Third Challenge is shooting: Once I got to this point, I could wear it and walk around and it wasn't too bad. The reason why I haven't talked about it on PM or been using it, is what to do once I spot a coyote coming on a stand. The G24 and Wilcox option allows me to stow away and up if I want. No matter what I do, when I would go down to shoot, and put my head down, the entire rig gets very uncomfortable as your balance starts to go forward. I don't want to take the helmet off during a coyote stand to shoot, but this could be an option.
I was actually waiting for
Phenom to arrive, because that is lighter and thought I would try that before posting. After messing around with this for awhile, my thought goes back to a selfie stick is about $10-$15, is more versatile, and is most likely what I will use.
