## What reviewers say

**Leupold BX-2 Alpine HD 10x42** — Two whitelisted hands-on testers — Field & Stream and GearJunkie — reviewed this exact model (BX-2 Alpine HD 10×42), both recommending it as a strong sub-$300 value with above-average optics, smooth focus, and a rugged, weather-resistant body. Both flag a looseness issue (F&S the diopter, GearJunkie the eyecups); GearJunkie also notes it lacks the hydrophobic lens coating of higher-end Leupolds. No lab-measured numbers were published.
