Extra Features of the 72 mm Bino-One Spotting Scope
Quality Interchangeable Eyepieces: The BOS72 comes with two 12.5 mm long eye relief (20 mm) 1.25" eyepieces. The lenses are fully multi-coated and install easily into the binoviewer with twist lock collars.
IPD Scale: Set the distance between the two eyepieces by sliding the interpupillary distance scale up or down until you find the spacing that is most comfortable. The scale runs from 58 mm to 74 mm and is conveniently located between the eyepieces on the binoviewer body.
Diopter Focus: Don't have 20/20 vision? Simply turn the Diopter Focusing Ring, with its + and - markings, until the image is sharp.
360 Rotation: The green collar that connects the binoviewer to the spotting scope can be loosened, allowing you to rotate the eyepieces for the most comfortable viewing. This is especially nice when doing astronomy and the scope is pointing up near the zenith!
Serialized Product: A name plate on the back of each spotting scope is stamped with a serial number. This allows for better quality control at the manufacturer level and better. more targeted service should you require it.
Cool Vixen-type Dovetail: You can attach your Bino-One to either a tripod (via a 1/4-20 threaded hole) or to an alt-azimuth or equatorial mount via the included Vixen-Style Dovetail plate.
Strong Carry Case Included: Each spotting scope comes in its own hard carry case for the ultimate in protection for storage or travel. Custom cut foam snuggles your scope with binoviewer and eyepieces attached, and there is room for more eyepieces should you desire.
