Amazon Basics 7x50 High Power Binoculars, Wide Field of View, FMC Optics, Tripod Compatible, Black, 1 Pack

High-power low-light observation: Featuring a massive 50mm large objective lens, these binoculars gather abundant light to deliver bright, clear images even at dusk, dawn, or during night-time stargazing. Please note that this professional-grade optical system is specifically designed for long-distance viewing and is not intended for close-up observation within 32 feet (10m). Stable viewing with fixed magnification: Equipped with a professional fixed 7x magnification (non-zoom) that is the gold standard for marine navigation and astronomy. Unlike high-magnification or zoom binoculars that suffer from dizzying hand-shake, this stable 7x system ensures a steady, comfortable view that minimizes eye strain during extended observation. Crisp focus in 3 simple steps: Prevent blurry images by balancing your left and right vision! Before first use, adjust for your individual eyes: 1. Close your right eye and rotate the smooth central wheel until your target is sharp. 2. Close your left eye and rotate the right-eyepiece diopter ring until the view is crystal clear. 3. Open both eyes—now, you only need to use the central wheel for different distances. Solid heavy-duty build and tripod readiness: Weighing a solid 28.2 oz (800g) due to its generous, high-density optical glass lenses, these binoculars are built for stability. To prevent arm fatigue during long stargazing or bird-watching sessions, we highly recommend mounting them to a standard tripod using the integrated 1/4"-20 threaded socket (adapter not included). High-contrast optics with robust housing: Designed with precision-aligned optical elements and multi-coated lenses to enhance center resolution and reduce reflections. Wrapped in a rugged, shock-absorbing rubber armor, the body provides a secure, non-slip grip, and the kit includes a carrying case, neck strap, objective covers, and a microfiber cleaning cloth.
