It’s really too bad nvision has chosen to use their customer base as their r&d department rather than do it themselves. Not one person I know that actually uses their stuff a lot and isn’t getting free shit from them has had good things to say. Most I know have sold their halos and moved on. My hunting partner unfortunately has not sold his halo lr and after 2 years of trying to get it working right he is now sending it back for repairs/replacement for the 9th time and they still are claiming it’s just bad luck
