HHA’s Tetra LT 4-Pin Bow Sights offer a compact, lightweight, and versatile sighting option to bow hunters and 3D shooters alike. These ultra-durable sights are available with either a fixed frame or dovetail bar (both offer a super smooth 2.1” of travel), a pin size of .010 or .019. The 4-pin configuration of these sights also provides greater versatility, and require less in-field adjustments which also helps cut down on game-spooking movements which hunting from a tree stand. To ensure superior accuracy in virtually any lighting condition, the Tetra LT 4-pin 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 Blue Burst light (sold separately) can be added for enhanced low light performance. One of the Tetra LT’s more notable features is its yardage adjustment wheel and patented R. D.S. sight tapes, allowing for 20 to 80 yard accuracy with the quick turn of a wheel as well as an easy sighting in procedure. Additionally, the Tetra LT sights feature 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 Tetra LT sights 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. In addition, HHA is a veteran-owned company, and all HHA products are proudly made in the U. S.A.
