The Oracle laser-rangefinding bow instantly calculates and shows the exact aiming point for any distance and shot angle. The Oracle will learn the trajectory or drop for two different arrow configurations and will accommodate up to 176 inches of drop at 100 yards. Most bow set-ups will be able to achieve 80-110 yards depending on bow speed and arrow weight. The Oracle bow sight automatically detects when the sight is mounted for a left-handed bow and reverses the LED readout. One CR123 battery powers the sight for 1,000-2,000 cycles.
