There are a LOT of great cameras out there these days to pick from, but when I upgrade again here before too long, I'll likely be switching over too the Sony AX53 or AX100 instead of the Canon XA10 or 20 like I have been using over the last few years. They are still very good cameras, and reasonably priced though so don't overlook them depending on your budget. 4k allows you the ability to film in 4k with pretty much no zoom involved if on an average bowhunt for example and allow you too crop in as close as you'd like during the edit. One less thing to worry or even think about while in the field.

For arms, there are a lot of them out there, but the Fourth Arrow Carbon Arm is hard too beat. Super light-weight, and when you're self filming, you'll like the lightness of that arm. I've been using it for 2 seasons already and love mine.

Aside from that, I started adding 2 or 3 action cameras too my stands when filming to always have 2 cams 100% dedicated too the hunter from different sides at all times, while another gets an overhead view of in front of them, and the main camera only on the animal. Seems like a lot, but easier than recreating the events later, which in my opinion makes for a more real feel too it as the post shot reaction is 100% real as it happened. I don't think you can ever really replicate that.
