There are many reasons to have a good pair of binoculars around whether you are boating, camping, stargazing or hunting, being able to identify things in the water can help you in many ways. Bushnell Binoculars come in compact or large objective lenses and the Leupold binoculars have the same quality as the Leupold rifle scopes. Zeiss binoculars and Konus binoculars give you a different style and it’s up to you on what you think you need. There are differences in clarity and light gathering abilities, but it will depend on how much you need and what your budget is. The real differences are noticed on cloudy days or low light. There are many smaller compact optics that are very good and have a wide field of view.
I do think it is a good idea for anyone that is serious about hunting to bring a small pair of binoculars. Many binoculars like Zeiss binoculars may seem expensive at first but peering through binoculars to identify a target is easy and safer to do than using your rifle scope. Yes, you will be bringing slightly more weight with you but being able to constantly scan your territory might mean more opportunity for taking game. If you use a good pair of binoculars you may see things in the sky that were just out of your naked eyes visibility and you may see passing satellites or shooting stars.
