The BX-4 Range HD Gen 2 TBR/W 10x42 fuses our DNA engine and ballistics software with the optical performance diehard hunters and shooters demand. Now you can spot and range targets without switching optics. It has a maximum range of 4000 yards on reflective targets and 2000 yards on trees. Its high-contrast red OLED display delivers crisp readouts in any light while edge-to-edge HD clarity reduces eye strain for longer glassing sessions. - Elite Optical System - TBR-W - Bow Mode - Last Target - Line of Sight (LOS) Mode - Interchangeable Form-Fit Eyecups - Archer's Advantage - Ergonomic Design - Easy-grip Standoffs - Tripod Ready - Smooth Focusing - Waterproof and Fogproof - Tripod Compatible (1/4-20) Yes - Rifle Angle Compensation TBR/W - Archery Angle Compensation Bow Mode - Battery Type CR2 - True Ballistic Range (TBR) No - Horizontal Distance (Trig) No - Display Type OLED - Display Color OLED (Red Display) - Flightpath No - Trophy Scale No - Length (in) 5.9 - Weight (oz) 37 - Magnification 10 - Objective Lens Diameter (mm) 42 - Linear FOV (ft@1000 yd) 334 - Angular FOV (Degrees) 6.2 - Eye Relief (mm) 17 - Min Diopter (dpt) 78 - Max Diopter (dpt) 3.5 - Exit Pupil (mm) 4.2 - Close Focus Distance (ft) 13 - Interpupillary Distance Max (mm) 76 - Interpupillary Distance Min (mm) 56 - Light Transmission Left Channel (%) 82 - Light Transmission Right Channel (%) 78 - Accuracy to 125 (yd) .7 - Accuracy to 1000 (yd) 1 - Accuracy above 1000 (yd) % .2 - Battery Life (Actuations) 3000 - Max Range Deer (yd) 1300 - Max Range Trees (yd) 2000 - Max Range Reflective (yd) 4000 - Min Range (yd) 12 - Laser Classification Class 1M
