Can't help you. Even if I wanted to. A lot of my hunting equipment still works but much has been discontinued. Either that or the company was sold or folded. A lot that will help a new guy.
Never had a feeder. Never saw the advantage of sitting in one place for a whole day. Just sitting there staring at a feeder. Some hunting ! Waiting until you have to go and fill up the feeder.
Never worried about rifles. Just got one of fifteen kinds or so that works good. Everyone's got a favorite; the one they use a lot.

Lots of electronics these days for hunters. GPS's, iphone, distance finder, and a whole hassle more.
One of my electronic pieces is an old Timex watch. Have to get a new battery for it. The old one just went dead.
That and batteries for a flashlight is all I really need. Try to sell that idea to a new hunter.

And I never quite grasped that over eating and hunting went together. My compass is too old for that. It's use to the long hikes I've made. So much for helping a new hunter. Don't have to walk much if you're guarding a feeder.
