Leupold BX-4 Range HD Gen 2 Rangefinder 12x50mm

Built to take on the harshest conditions, SX-4 Pro Guide HD, 15-45x65mm features an incredibly rugged magnesium body that is 100% waterproof and fogproof and an oversized eyepiece designed to maximize light and minimize strain, even on the longest days.

Featuring Leupold’s Elite Optical System, it offers excellent dawn-to-dusk light transmission for a bright image when it matters most, elite-level glare reduction in harsh light, and the resolution and clarity that diehard hunters and shooters demand. The straight eyepiece is ideal for glassing downhill or through a truck window. The straight eyepiece is also a bit easier to pack.

Like all Leupold spotting scopes, the SX-4 Pro Guide HD Gen 2 is guaranteed to perform for life, or we'll repair or replace it for free. Whether you're going on your first big game hunt or helping repeat clients tag out season after season, this spotter is an essential part of your kit.

Elite Optical System - offers excellent dawn-to-dusk light transmission for a bright image when it matters most, elite-level glare reduction in harsh light, and the resolution and clarity that diehard hunters and shooters demand.

TBR-W - True Ballistic Range® / Wind (TBR®/W) technology provides ballistically calculated ranges for extremely accurate shots at longer distances and steeper angles. It can also generate a hold point for a 10-mph wind at a 90-degree angle out to 800 yards.

Bow Mode - With its TRIG function, Bow Mode is an excellent "set it and forget it" feature that is simple to use and accurate out to around 70 yards and for angles less than 20 degrees. This function is ideal for Western spot-and-stalk hunters and tree-stand hunters, providing 10-ring target level accuracy.

Last Target - guarantees that the rangefinder identifies the most distant target along the laser's trajectory, preventing inaccuracies caused by adverse weather conditions like rain, snow, or fog.

Line of Sight (LOS) Mode - calculates the distance to a target in a straight line, regardless of any incline or decline.

Interchangeable Form-Fit eyecups - come in three different sizes, allowing you to customize your viewing experience based on your preferences. Choose the winged eyecups for blocking out stray light, opt for the medium eyecups for all-around comfort, or select the low eyecups designed specifically for use with glasses

Archer’s Advantage mode - uses your arrow weight, arrow velocity, and peep height to deliver precise range calculations made for shooting at steep angles or over long distances.

Leupold's ergonomic design - ensures their products are slim, lightweight, and fit well in your hands no matter what size they are.

Easy-grip Standoffs - Easily locate the buttons with easy-grip standoffs, even through thick gloves. Prevents accidental activation and battery depletion.

Tripod Ready - A built-in 1/4-20 rotatable tripod adapter port makes it easy to mount to a tripod.

Smooth Focusing - features an extremely smooth focusing system for fine adjustments.

Leupold pioneered modern waterproof and fogproof technology using advanced internal gasses and sealing methods that withstand extreme temperatures and elevation changes, so the internals of the optics stay moisture free and crystal clear for life.
