What To Look For
Binoculars for any Situation
Binoculars are largely defined by two measurements, the magnification and the objective diameter. These measurements are commonly described in forms such as 7x50 or 10x42. The first number represents a binoculars' magnification, and the second number indicates the lens diameter.
Most important in determining low light capabilities is the second number. In general, the larger the lens diameter, the more light is allowed in and the better the binoculars will handle low light conditions. Of course, a number of other factors go into low light success, including the lens coating and image stabilization. That tends to matter more when light gathering is a priority.
Common Pitfalls
When it comes to low light, it is easy to have too much of a good thing. For low light viewing, consider limiting your magnification to 10 or even 7. Higher magnifications necessarily narrow the field of vision; that can also limit the amount of light absorbed by your binoculars.
Where To Buy
While outdoor stores will often stock binoculars, you want to make sure to find a shop with knowledgeable staff. Often hunting stores will have employees who know the specifics of different binocular pairs in comparison with one another. Never buy binoculars in a store that doesn't allow you to try out each pair. Make sure to find a store where you'll feel comfortable spending the time to become acquainted with the binoculars.
Cost
Low light effectiveness often comes at a premium. As of 2009, a solid pair of Nikon binoculars (Monarch ATB) that will serve you well in low-light conditions can be had for $429 from Trails.com. See the link in our Resources section. However, prices go up quickly and drastically from there. Specialized birding binoculars--designed to work well in low light and reproduce colors perfectly--can cost $800 or more.
Comparison Shopping
Try before you buy. If you've narrowed it down to a particular model, consider checking online for better deals. Make sure to read everything you can about your chosen pair in advance. You'll want to know how heavy they feel, how ergonomic they are and how well they work with certain activities, whether it's canoeing or bird watching.
Accessories
Absolutely vital to a pair of binoculars' usefulness is a padded carrying case and a cleaning cloth that will not damage the lenses. You should also consider individual eye covers and a birding tripod that will allow for a more steady view while using your binoculars.
Insider Tips
A common mistake buyers make when looking for suitable binoculars is to trust the numbers over their own senses. While the two numbers associated with every pair of binoculars is important, there are a number of other factors at play in any pair. As such, you really need to try them out for yourself.
