The IQ™ Micro 4 Pin Bow Sight features an incredible yet extremely simple shooting tool—Retina Lock Technology. Just center the green dot found at the top of the sight, and you've virtually eliminated the chances of torque throwing off your sight—perfect alignment with every shot, at every distance, every time! Precise micro-adjustment knobs allow quick and easy adjustments to elevation and windage, and the tool-free locking knobs allow you to lock down your sighted-in settings with zero chance of movement. The dual-position mount allows two options for mounting the sight, customizable to your particular style of shooting. All-aluminum design is strong and lightweight; 4 ultra-bright .019 pins.
