The Diamondback HD smashes the scale of price vs performance, delivering a rock-solid optic that optically punches high above its class.
The eye-cups on the Diamondback HD binocular twist up and down so any viewer can see the full field and enjoy comfortable viewing with or without eyeglasses. When not using eyeglasses or sunglasses, keep the eye-cups fully extended. For the best viewing when wearing glasses, twist eye-cups down.
The interpupillary distance (IPD) is the distance between the center of your left and right pupils. Match the IPD of your eyes and your binocular by rotating the barrels in or out until you see a single image free of shading.
