It features an enlarged porro prisms and anti-reflective multi-coatings to maximize field of view, cross-field resolution and low light performance. An 18mm eye relief eyepiece and large depth of field provide the best chances for stable, comfortable viewing under constant motion with or without glasses. With a fully nitrogen gas-filled waterproof housing and specially mounted prism assemblies, the internal elements are well-protected. A strong, single die-cast aluminum body with thick rubber armoring is durable in even the harshest conditions.
