These days variable are the most popular. In my opinion they get the nod over fixed-power scopes. The benefits of the fixed power is there are fewer moving parts and fewer things that can go wrong, and you don't have to be concerned about having accidentally set the power ring at 10X or above and then have an animal step out at 10 paces. Under such circumstances all you'll likely see is hair without the benefit of knowing to what part of the animal's anatomy that hair belongs. Fixed power, especially lower fixed-power scopes, with a wide field of view are ideal for mounting on guns you'll using to hunt dangerous game at close range.
Variables however have greater versatility.
That way when hunting in close cover I have the power setting on the lowest setting. Then should something be close, I can see the entire animal, and also have a wide field of view. Should an animal appear at a much longer range I've got the option to increase the magnification. The EdersHunting catalog offers a wide selection of sport optics.
