HHA’s Optimizer Ultra X Bow Sight delivers versatility and high performance at an unbeatable price. Perfectly suited for 3D shooters and bow hunters alike, the Optimizer Ultra X is equipped with HHA’s patented R. D.S. Sight Tape technology, allowing for precise 20 to 80 yard accuracy with a smooth lever action, and water resistant tape allows for use in adverse weather. To ensure enhanced accuracy in virtually all lighting conditions, the Optimizer Ultra X is available with an optional mechanical rheostat light – a handy feature that can brighten or dim the pins by exposing/covering the fiber optic threads, and low light performance can be enhanced even further with the use of a Blue Burst light (sold separately). Other features of the Optimizer Ultra X includes the new Infinite Adjust slotted bracket, which completely separates the your elevation adjustments from your second axis adjustments to help speed up your sight in and setup procedures. In addition, the Optimizer Ultra X is compatible with lens kits, and like all of HHA’s products, is proudly made in the U. S.A. Features of the HHA Optimizer Ultra X Bow Sight: Patented R. D.S.
