Bushnell 18-36x50 Sentry Spotting Scope - Black, Porro Prism Optics

The Bushnell 18-36x50 Sentry spotting scope delivers serious optical performance in a package built for field use. This porro prism spotting scope spans an 18x to 36x magnification range with a 50mm objective lens, giving you the flexibility to glass distant terrain at lower power or dial up the magnification when you need to pick out details. Whether you're scouting game, surveying a property, or setting up for a long-range shot, the variable magnification handles both wide-field scanning and pinpoint observation without swapping eyepieces.

Built with multi-coated optics, the Sentry renders excellent edge-to-edge clarity, especially during those critical dawn and dusk hours when most hunting and field work happens. The waterproof and fogproof construction means it'll stand up to backcountry weather—rain, dust, temperature swings, and humidity won't compromise the optical path or mechanical reliability. At 31 ounces and 14.7 inches long, it's compact enough to pack into a daypack or glass case without dominating your gear load, making it genuinely portable for day trips and multi-day missions alike.

The 16mm eye relief and 20-foot close focus keep the viewing experience comfortable and versatile, whether you're bracing against a tripod or glassing from an improvised rest. If you're after a spotting scope that doesn't pretend to be something it's not—no gimmicks, solid construction, fair optics, and a real price tag—the Sentry is worth your attention.

Frequently Asked Questions

What magnification range does this spotting scope cover?

The Bushnell Sentry offers a variable 18x to 36x magnification range, letting you dial in the power you need. Lower magnification is better for scanning wider areas, while 36x brings distant targets into sharp focus for detailed observation.

Is the Sentry waterproof and fogproof?

Yes. The scope is fully waterproof and fogproof, so it can handle rain, spray, humidity, and temperature swings without internal fogging or water intrusion. This makes it reliable for hunting and field use in unpredictable weather.

How much does it weigh and is it portable?

At 31 ounces and 14.7 inches long, the Sentry is compact and lightweight enough for backcountry day trips, scouting missions, and extended field days. It packs easily without taking up excessive space in a pack or case.

What is the eye relief and close focus distance?

Eye relief is 16mm, which gives you comfortable viewing from most positions and accommodates both bare-eyed shooters and those wearing eyeglasses. Minimum close focus is 20 feet, so you can focus down reasonably close for nearby detail work.
