Leupold BX-4 Pro Guide HD 12x50 Gen 2

The Leupold BX-4 Pro Guide HD 12x50 Gen 2 is a high-magnification binocular designed to make distant targets and landscape detail easier to resolve. Its 12x magnification and 50 mm objective lenses deliver extended reach, while a measured linear field of view of 257 ft at 1,000 yd (4.9° angular FOV) helps you track wider scenes without frequent repositioning.

Key features and practical benefits:

• 12x magnification and 50 mm objective — increases visible detail at long range compared with lower-power models.
• 257 ft linear FOV @1000 yd (4.9°) — balances reach with a usable field of view for scanning terrain.
• 16 mm eye relief and interchangeable Form-Fit eyecups — supports comfortable viewing and usable eye positioning for extended glassing sessions.
• 4.2 mm exit pupil and 10 ft close-focus distance — provides a bright image at range while allowing examination of nearer objects when needed.
• Compact profile and 6.8 in length at 29.3 oz weight — a packable option that stays relatively portable for field use.

This Gen 2 model also notes upgraded optical glass and improved lens coatings intended to enhance resolution and reduce glare. The binocular’s interpupillary distance adjusts from 56 to 74 mm to fit a range of users.
