It's not so bad if you are hunting from a fixed location. I'm in a ground blind, ladder stand or climber stand hunting deer and hogs and the biggest challenge is pulling it up the rope after I'm in my stand. And that just making sure it doesn't bump into anything that could do damage.
After I'm sitting in a tree stand it's either in my lap resting on a shooting rail or hanging from a hook. In the ground blind it's on a tripod. Even holding it free hand because of the RDX bow weight distribution, it's not bad at all.
Cost is really pretty reasonable. More expensive than a traditional crossbow scope but about 1/3 the price of a comparable thermal smart scope. Pictures and video automatically taken on the pull of the trigger in HD quality, automatic ranging capability at the press of one button, impressively long battery life at 18 hours, live image sharing via wifi or bluetooth, capable of having multiple weapon profiles. It's a pretty slick device.
