ABOUT THE BUSHNELL SENTRY 18-36X50
The Bushnell Sentry 18-36×50 spotting scope offers a versatile and compact solution for observers requiring both portability and effective magnification. Unlike larger, heavier models, its 50mm objective lens and 18-36x zoom eyepiece are integrated into a single, streamlined unit.

The multi-coated optics significantly improve light transmission, delivering bright and clear images with good contrast. Its Porro prism system contributes to a wide field of view and enhanced depth perception. Ideal for observing wildlife, scanning distant landscapes, or checking targets at the range, this scope is built with rugged, rubber-armored housing for enhanced durability and grip.
