Deer vocalize in several different ways, and very seldom is it the same every time. Being able to adapt to your situation when the golden moment arrives can be the difference in a buck of a lifetime or just another story of the one that gave you the slip. Big bucks are big bucks for a reason as they become educated over the years and are very wary of noises that don't sound natural. This can make using a game call intimidating for beginners.
Don't get caught in the woods again with a one-dimensional call, be versatile and be prepared to notch that tag this season by using a change-up in your calls.
