HHA Sports has introduced its new Optimizer Tetra series of adjustable, single-pin bowsights starting with the Tetra Max. With an infinite adjustable front end similar to the one first introduced on the original Tetra sight, the Tetra Max allows the shooter to make precise vertical adjustments to fine tune his or her 20-yard mark, leading to a more accurate yardage tape and extending the shooter’s effective range. The HHA Sports Tetra Max has the company's patented R.D.S. (Range. Dial. Shoot.) technology so shooters can get their bow dialed in at 20 and 60 yards and be on target — to the yard — out to 80 yards. It is available with a fixed hunter version frame (photo above), or with a dovetail tournament addition. Single-pin and four-pin models available. MSRP: $379.99-$509.99. Contact: www.hhasports.com
