Serious glass for serious hunters. The Swarovski ATS/STS series delivers outstanding optical performance in a lightweight unit that is perfectly suited for the mountain hunter. The 65mm is the most lightweight in the ATS/STS lineup and delivers top of the line edge to edge clarity and color fidelity in an easy to use, straight spotting scope kit. If you're looking for superior light gathering, the ATS/STS 80mm provides 56% more surface area on the objective lens to gather a lot of light for twilight conditions. With two eyepiece options - the 20-60x for a bit more zoom, or the 25-50x for a wider field of view. Available in an angled (ATS) or straight (STS) body.
