Tasco Essentials 10x25mm Porro Binocular

As powerful as it is simple to use, the black Tasco 10x25mm Porro Binocular sports reverse-Porro prims to give them a more compact form factor that is easy to stow in a pack, purse, or pocket and comfortable to hold. Fully coated optics help capture as much light as possible while boosting contrast, and the wide viewing angle ensures the entire scene unfolding before you is comfortably in your field of view. For more detailed observations, the binocular has a short close-focus distance so small visitors to feeders like hummingbirds or butterflies can be clearly seen from as little as five-feet away. Tasco includes a carrying case and strap, and with a weight of just 8.8 ounces it won’t cause neck fatigue or add too much bulk to your load.
