S.3A - 20-40X67

$ 1,800
Color: Grey / Orange

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.

Choose between the variable magnification zoom eyepiece for field use or a fixed reticle eyepiece to aid in target and competitive shooting scenarios. This offers an excellent balance between portability and performance, allowing for more freedom of mobility.

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.
