LX3 Professional series. 30mm main tube. 56mm Objective Lens for Optimum Throughput of Light. Set the scope to 8x and the scope transmits more light to your fully dark-adapted eye than it can use. This extends the maximum distance you can identify targets at at night by a factor of eight. With aiming points that compensate for distance as well as cross-winds Lynx SA Hunter reticle is practical, easy to use and provides plenty of functionality. It is calibrated in metres for distance and km/h for winds and is designed to work with most popular manufactured ammunition. The bold reticle lines are easy to see in poor light, even if your eyesight isn't perfect, and you can light up up the centre aimpoint of the crosshair if if you need to.
