Bushnell is the leading brand in high-performance binoculars, and the Falcon series offers powerful magnification at an economical price. Versatile, and ideal for stadium sports, bird-watching, hunting, and many other outdoor applications, the 10×50 model boasts a durable design and rubberized, abrasion-resistant finish. An InstaFocus lever provides smooth feedback, with just enough tension to fine-tune magnification, while a Porro prism and coated lenses provide sharp viewing. For those who wear eyeglasses, or sunglasses on bright days, clever fold-down eyecups protect your lenses from scratching.
Making Eye Adjustments (Figure 1):
The distance between the eyes, called “interpupillary distance,” varies from person to person. To achieve perfect alignment of lens to eye, follow these simple steps. Hold your binocular in the normal viewing position Grasp each barrel firmly. Move the barrels closer together or further apart until you see a singular circular field. Always re-set your binocular position before using. Improper alignment of the interpupillary distance can cause double-images.
How to Adjust for Individual Eye Strength:
Bushnell Falcon binoculars utilize the “Insta-Focus” focus system. “Insta-Focus” binoculars have a central focusing lever between the barrels. Focus at any far or near distances can now be attained simply by pressing the “Insta-Focus” lever.
Eye Cups (Figure 3):
Bushnell Falcon binoculars are fitted with rubber fold-down eyecups designed for your comfort and to exclude extraneous light. If you wear sun/eyeglasses, roll down the eyecups. This will bring your eyes closer to the binocular lens thus providing improved field of view.

Excellent inexpensive binocular These binoculars perform very well during daytime and are good for the occasional birdwatcher or for viewing any outdoor event. The light weight and the insta-focus make them very easy to use. I bought them for stargazing (very tight budget!) and I am very satisfied with them giving what I paid. I have been able to locate and clearly see many Messier objects (ie. M22, M13, M11, M3, M5 and the great Andromeda Galaxy M31, and many star clusters such as M39 and the coathanger) and double stars…
Cheaply constructed to barely do the job These binoculars cost a hair over twenty five bucks on amazon right now – you’re not going to beat that deal in terms of value for money anywhere. They have decent optics.
Bargain Binocs Get the Job Done I bought a pair of these on sale (from my “gold box” — 10×50 is supposed to be the ideal for stargazing. I figured that this might come at the price of some chromatic distortion (tolerable) or difficulty focusing (intolerable). Last night was a “clear” night here in the South Bay. I live about a mile inland, on the coastal edge of Los Angeles’ vast light pollution. No marine layer, and I quickly pulled the full moon into focus, then adjusted the other eye-piece. They work for me, but if my…
