Defense forces and intelligence agencies use binoculars to observe the enemy from a safe distance. The quality of a pair of binoculars rests on their crystal clear visibility.
If you are planning on using your binoculars for birdwatching you want to look for a pair that is designed with good image quality. The result is appreciable for many people considering the easier mobility and simpler operation of the binocular equipment. Early recorded patents indicate that telescopic monoculars were made in seventeeth century.
If you will be staying in one spot for a period of time then it might be to your advantage to consider mounting the binoculars on a tripod which would free up both hands and not require you to find the viewing area, refocus, and keep steady each time you pick them up. Bird watching binoculars seem to run along the same lines.
In order to define the quality performance of their products, binocular makers present the field of view in mathematical conversions that show a variance of fields. You can find some secondhand models at affordable prices. Most compact binoculars have an ultraviolet protective lens that safeguards your eyes.
So, get out there. This advice is given in much the same vein as buying all the house you can afford.
