Kowa TSN-66 PROMINAR with TE-11WZ ll zoom eyepiece

Built for those who want to travel light without sacrificing image quality, the TSN-66 PROMINAR packs Kowa's flagship optical technology into a compact, lightweight body. It delivers a level of detail and clarity normally reserved for much larger, heavier spotting scopes — making it a favorite for backcountry hunters who need to keep pack weight down.

Key Features:

• 66mm pure fluorite crystal objective lens for true-to-life color and minimal chromatic aberration

• Dual focus system (rear + front wheel) for fast coarse adjustment and precise fine focus

• 100% magnesium alloy body — rugged, compact, and significantly lighter than large-objective scopes

• Fully waterproof, nitrogen-purged for fogproof performance in any weather

• Smooth twist sunshade with built-in aiming sight for faster target acquisition

• Bayonet eyepiece mount, fully compatible with the Kowa System — eyepieces, digiscoping adapters, extenders
