The traditional box-style turkey call has been around since at least the turn of the century. It is so easy to use with reasonable proficiency that many dismiss as a beginner's call. That's a mistake. The box call is an excellent all-around turkey call and works well for all skill levels. It is one of the loudest of turkey calls and its sound also carries well.
Wooden boxes are vulnerable to moisture.
I carry a bread-loaf bag, using my box inside it on damp days. Occasionally rough-up the lid with medium grit sandpaper but do not sand the lips of the box. An accomplished box caller can not only yelp and cluck but also purr, cut and cackle right along with any other type of call. Cutting, cackling and of course the fighting purr have their place, but with an ultra-careful late season tom, you may need to throttle back on the aggressive calling. Stealthy woodsmanship is very much an asset.
