S.3S - 20-40X67
The S.3 builds upon the excellence of our original premium S Series spotting scope glass and performance, and takes it to the next level in both size and form factor. The S.3, featuring a more compact design and a detachable eyepiece, offers an excellent balance between portability and performance. Positioned between our full-sized S.1 and the popular ultra-compact S.2, the S.3 20-40x67mm provides a high-powered solution across a wide range of magnification levels with a smaller objective lens.
For hunters, target and competitive shooters, birders, and wildlife observers who demand elite-level performance and the flexibility of switching to alternative eyepieces in the future, the S.3 series is our top recommendation.
Just like the rest of the S Series lineup, the S.3 incorporates fluorite glass, recognized as the premium choice for larger objective lenses. This exceptional glass ensures razor-sharp clarity from edge to edge, exceptional performance in low light conditions, and the delivery of vivid, distortion-free, and brilliantly bright images.
The Maven S Series represents our elite line of optics, designed to fit your specific needs, delivered for a fraction of the cost to comparable spotting scopes and stacks up with the most celebrated and expensive scopes in the world. Whether you choose a stock color unit or configure your own custom-built optic, our modern sportsman-inspired designs are paired with the best available materials and state-of-the-art technology to create an uncompromising optic.
Includes lens caps and double-layered microfiber storage bag.
