The Tetra Max Tournament sights come with a dovetail bar mount. To ensure superior accuracy in virtually any lighting condition, the sights are equipped with a mechanical rheostat with an integrated scope ring, which can be used to brighten or dim your sight by exposing/covering the fiber optics, and a light can be added for enhanced low light performance. One of the more notable features is its two interchangeable yardage adjustment wheels – an exclusive feature of HHA. The wheels also feature an integrated magnifier or a better view of your yardage marks, as well as an ultra-fine brass needle. These features provide a higher degree of fine-tuning. Additionally, the sight features macro gain adjustments for windage by loosening the knob and sliding the scope back and forth, precise micro adjustments, and 1st, 2nd, and 3rd axis adjustments. Other features of the sight include the Infinite Adjust Plate, which completely separates the elevation adjustments at 20 yards from the 2nd axis adjustments, making the sight in and setup process even faster.
