The Athlon Argos series of spotting scopes were created with the aim of providing users with excellent optical quality and a user-friendly experience. These scopes are equipped with wind band fully multi-coated lenses and porro prisms that have phased coating. This combination ensures that users can enjoy great clarity and brightness while using the spotting scope. The chassis of the scope is made from lightweight composite material and is protected by a layer of rubber armor. Additionally, it is both fog proof and waterproof, and filled with nitrogen gas to prevent internal fogging and promote better thermal stability. The product also comes with a soft case that has been specially designed to allow users to mount the spotting scope on a tripod and use it while the soft case is still on.
