If you want to drop 200 coins on optics to hunt Elk, than feel free to do so, But,

You do not need that kind of glass to find/evaulate critters that weigh several hundred pounds,

Elk are easy to spot, Big Bulls are almost blonde, they can stick out like sore thumbs, like Dall sheep, they really don't blend in all that well,

take what you have, or purchase outright. Good optics do make hunts more enjoyable.
