The C 10x25 ACP Binocular from BSA Optics is an inexpensive way to have reasonable magnification available in your jacket pocket, purse or pack. Weighing in at only 8 ounces and less than 5 inches, this dual hinged, magnesium binocular is as portable as it gets. And the optical enhancements have not been left on the factory floor either. Fully coated magnesium fluoride (MGFL-2) blue BAK7 roof prisms deliver crisp, clear images with increased light transmission and anti-reflective delivery. The roof prism design contributes to the light weight and compact housing. A dioptric adjustment allows for individual eye customization. And the center focus knob is conveniently ribbed for non-slip use.
