The other day I found some binoculars that I like. They are the 8×42 waterproof, long eye relief, BaK4, multi-coated binoculars by Alpen. They are easy to handle and carry well.
Why not just let the child have your old best night vision binoculars? That’s quite alright providing that the binoculars actually fit the child. One last thing, and it’s a major thing, that is different about children’s binoculars is the interpupil distance. That is, the distance between the eyepieces. Adult binoculars are typically too wide for a child’s smaller face. Adult binoculars have a hinge apparatus so that they can be adjusted to fit adults with different face shapes. The interpupil distance can be easily changed just by grasping the binoculars and moving the tubes closer or further apart. So, the adult ones can be made smaller, but not small enough to fit most children.
You’re going to be toting your binoculars through nature. After all, that’s where the birds are. Don’t be alarmed if your birding binoculars get banged against a fence post or a tree. This could cause cheap or poorly made binoculars get out of alignment. This is very annoying as it will result in double images. Just as bad, if the tubes aren’t sealed properly they can allow moisture inside and fog up or even get moldy. Some of the best birding binoculars are sealed with o-rings and filled with nitrogen gas.
The above statements may sound bold, but I really believe it. I grew up using whatever binoculars we had on hand. Many of them were very old sets of binoculars, and all of them were discount models purchased at department stores for very low prices. To make a long story short, I didn’t know any better. I just assumed that expensive binoculars were for rich people, and I didn’t think they were necessary.
Though small binoculars might sound good as they are not bothersome to pack around, you will pay for that when you look through them. The image quality suffers as a result of being so small and they are uncomfortable to use. With big cheap binoculars, you can get a quality image, but they will not last long with hard use and you won’t want to pack them around causing them to not be there when you need them.
Practise by choosing an object to view and stand facing it directly. Make sure your whole body, including your feet is straight on it. Raise your head and look at the object.
Buy a set of Nikon Monarch 10×42 ATB Binoculars, and you won’t regret it. They are a high-quality set of binoculars that won’t let you down. To back them up, Nikon has a lifetime no-fault warranty, but I don’t think you’ll need the warranty.
