Leupold BX-4 Range HD Gen 2 Features TBR/W technology provides ballistically calculated ranges for extremely accurate shots at longer distances and steeper angles and it can generate a hold point for a 10 mph wind at a 90 degree angle out to 800 yards meaning a hunter gets a real firing solution rather than just a raw distance reading. Bow Mode uses the TRIG function as a set-it-and-forget-it feature accurate out to roughly 70 yards on angles under 20 degrees delivering 10-ring target-level accuracy for Western spot-and-stalk hunters and tree-stand archers alike. Last Target guarantees the rangefinder identifies the most distant object along the laser s path preventing false readings caused by rain snow or fog that could otherwise range brush in front of the animal. Interchangeable Form-Fit eyecups come in three sizes letting shooters choose winged eyecups to block stray light medium eyecups for all-around comfort or low eyecups suited to glasses wearers. Easy-grip standoffs make the buttons easy to find even through thick gloves while preventing accidental activation and battery drain and a built-in 1/4-20 rotatable tripod adapter port makes mounting to a tripod simple for extended glassing sessions. At 37 oz with a CR2 battery an OLED display and a diopter adjustment range of -3.5 to +3.5 the BX-4 Range HD Gen 2 is built to perform for life backed by Leupold s guarantee to repair or replace it for free.
