Vortex Diamondback HD 15x56 Binoculars

The Vortex Diamondback HD 15x56 Binoculars are packed with power and clarity. They use high-quality optics with HD clarity and up to 15x magnification. This makes the Vortex Diamondback HD a perfect pair of optics for long glassing sessions in an open country. Plus, its lightweight and durable design with magnesium alloy housing won’t weigh you down, keeping you mobile on your stalk. A rubber-armored exterior provides a non-slip grip for comfortable use.

Tripod Adapter

The Diamondback HD 15x56 Binoculars come with a tripod adapter that helps you mount them on a sturdy base for ultimate balance. Packed with features like superior image resolution, improved light transmission, and a durable, lightweight design, the Vortex Diamondback HD is a great choice if you are looking for a powerful pair of optics for your next adventure.

HD Optical Quality

At the heart, the Diamondback HD 15x56 is equipped with an HD optical system that offers sharp, clear images. A multi-layer dielectric prism coating further enhances the image quality, rendering high-contrast images. These binoculars offer up to 15x magnification in a 56mm objective lens.

Basic Smartphone Adapter (1.25-Inch)

The smartphone adapter connects your smartphone to your telescope, so you can capture images and video through the eyepiece. With its light, rigid frame, this accessory allows you to connect any smartphone to any telescope eyepiece with an outside diameter of 45mm or smaller. The additional magnification provided by the eyepiece allows your phone to capture great images of the moon and planets.

Durable Construction

This smartphone adapter installs easily by clamping over the top of an eyepiece. The smartphone is held in position with the help of tightening knobs that securely lock your phone in place. Some large and/or bulky phone cases (including folio-style cases) may need to be removed for the phone to fit in the adapter. The adapter stands up to rigorous field use thanks to its robust, durable construction with a metal body.

The Vortex Logo Hat (Black Camo) will have you rocking a sporty yet casual look that’s perfect for hunting season.
