If you've already got a 710, it will work, but if you are looking at buying a gun, I'd suggest a 700 if you are going Remington. And don't go for a package gun. Buy the optics seperate or get a gun with open sights.

Mouth calls are easy enough to use with a little practice, and I think they work a lot better than cheap electronic calls. But if you've got the money, a Fox Pro is worth every penny.

Any kind of camo will work as long as it breaks up your outline. Use the vegetation around you to help break up your outline a little more. Predators are very sensitive to movement, and you can't move once they focus on you. So have the gun ready at all times.

Something as simple as a feather and fishing line can help improve your odds. Tie a feather in a fence, branch, or something about 25-30 feet away where it can wiggle in the breeze. It's movement will help take some of the focus off of you.
