With the Field Logic IQ 4 Pin bow sight you can dramatically increase your effective range thanks to the innovative Retina Lock. The sight itself is a well made 4 pin sight using quality fiber optics in the pins and a bubble level to make sure you are not canting your bow to miss a shot. But the Retina Lock Technology is what really sets this sight apart from the rest. Centered on the top of the pin guard is a green dot with a black dot in its center, and this is what you should see if you are not canting or torquing or even having an awkward grip or body position. If you see shadowing however, you know your shot is going to be off for those reasons, and you can adjust accordingly. Because what might seem to be a minor deviation at 20 yards gets much larger as the distance increases.
