Product Description

From The Manufacturer

Tasco's best-selling Essentials line balances optical performance and quality construction, offering an affordable way to add a pair of high-quality binoculars to your household, pocket, or suitcase. The handsome, rubber-armored housing not only absorbs shock and protects them from bumps and bruises, it adds in a weather resistance factor should it decide to rain--or snow--at the big event.

For optimum versatility, these high-power binoculars quickly zoom from 10x to 30x power to zero right in on distant objects.

• Rubicon coated lenses
• 50mm objective lens
• Porro prism system
• Field-of-view (at 1,000 yards): 216 feet/72m (at10x)
• Features: Zoom, tripod adapter fitting carrying pouch and neck strap
• Weight: 32 ounces

Tech Talk

• Rubicon Coated Lenses: A Tasco exclusive, comprised of 14 different layers of multi-coating on the objective lens with a ruby-red tint to filter out red light for reduced glare in bright light.
• Magnification: Magnification is indicated by the first number given. For instance, "7x" means that you will see an object seven times closer than if you were viewing with the naked eye.
• Objective Lens Diameter: The objective lens diameter is indicated by the second number (e.g., 21mm), which indicates how much light is able to enter the binocular. The larger this number is the better your sight will be in lower light conditions.
• Porro Prisms: The distinctive, off-set binocular housings accommodate two internal porro prisms, which are used to elongate the light path to enable higher magnifications than primitive field or "opera" glasses. Porro prism binoculars typically deliver exceptionally high optical quality at more affordable prices than roof prism binoculars of the same power rating.

They are usable but not as clear as I'd hoped for. Zooming distorts the image.
