All the Redfields are fully multi-coated, nitrogen purged, waterproof, and shock tested. If you don't mind the 1" tube, it's a quality scope.
Some people prefer 30mm tube diameter because it helps with light transmission, but with a 52mm objective, I don't think that will be a problem. It is really only a consideration if you're out in the woods before dawn every day, and until after dusk.
I haven't personally looked through this scope, but on paper it seems well worth the price.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
