Sig Sauer OSCAR3 10-20x30 Compact Spotting Scope

SIG SAUER's straight-viewing OSCAR3 10-20x30 Compact Spotting Scope features a high-performing optical system enhanced with gyroscopic image stabilization. You will be able to see highly magnified jitter-free images with high contrast, true color, and high resolution thanks to multi-coated optical elements, BAK4 prisms, and low-dispersion (LD) optical glass.

For ease of use in outdoor environments, the housing is made of lightweight and durable glass-fiber-reinforced polymer and is protected with a rubberized covering for a secure grip. The body offers a compact straight-viewing configuration that is ideal for handheld operation and offers easy-to-use controls and knurled adjustment rings. For achieving desirable eye relief, the rubberized eyecup provides several twist-up positions. Also included with this scope are two CR2 batteries, a padded ballistic nylon case, and a lanyard.
