HHA Optimizer Lite. 1 pin on a slide. Bright, simple, rock solid and stupid proof.
I have the HHA 5500 with the rheostatoverlike 5 feet of fiber optic cable. 1 pin dead center inside a nice, easy to aim circular sight window with marks at10, 20, 30, 40 and 50 yards.I plan to keep it set at 25 and adjust it only if the deer comes inside 20 yards and I have time.
