“HiDefSpex has achieved a level of design and technology that clearly gives a shooter a competitive advantage. The New HDS Panther is simply a brilliant design. HiDefSpex Diamond Vision Lenses™, made of a bullet-proof material, enhance the visual sight picture with stunning clarity and create bright target color definition better than any other on the market. No contest. You need these Shooting Specs.”The HDS Panther is a new frame design that uses HiDefSpex’s exclusive light management system. The design produces an incredibly open site picture with no encroachment of the frame in the line of view. The frame uses our patented “Snap-Tec™ Lenses”, a 3 snap system that attaches the shield to the frame, allowing the shooter to quickly change lenses with ease to the optimal light transmission. Due to the superior strength of our bullet-proof lens material, we have the ability to drill through the lens (without stressing or cracking the lens) to add the “Snap-Tec Lenses”. In addition to the revolutionary lens changing system, the HDS Panther has implemented fully adjustable temple arms to provide the optimal fit for a shooter’s head size. The temple arms may be adjusted over 20mm in 5 secure positions. The HDS Panther uses our exclusive and patented “Ratch-Tec™” system of ball bearings to secure the adjustment of the temple arm. In addition, the Panther uses the same “Ratch-Tec™” system to provide an adjustable nose bridge.
