glad to hear you decided to take up bowhunting again.
i would recommend at least a grunt tube. it wouldnt have to be anything special, but they really do work oftentimes, its like anything else, it wont work everytime, but they are definitely worth the investment.
I also recommend hunting from a treestand. the deer are far less likely to see you, but i also hunt on the ground occasionally and as long as you're careful about movement and camoflage, you'll probably be fine. if you do hunt from the ground, i would highly suggest full camo from head to toe. Even in a tree, full camo is the best way to go. You don't necessarily need the most expensive scent eliminating carbon camo on the market, i just use camo jeans, jacket, gloves, hat and facemask, all of which can be found at walmart or some similar store. as long as you learn to hunt only when the wind is right, youll be just fine.
I think you'll have much better luck if you find a place and stay there than if you try to walk around. more times than not, it doesn't turn out so well. Thats been my experience anyway.
I hope this info helps. have a safe and successful season!
