Kowa 77mm Spotting Scope Comparison and Review

Take your nature observation, hunting, or shooting to the next level with this TSN-773 77mm Prominar XD Spotting Scope and TE-11WZ II Wide-Angle Zoom Eyepiece Kit from B&H. The angled scope employs multicoated, extra-low dispersion glass for bright images with minimal chromatic aberration. The eyepiece offers powerful magnification, a generous field of view, and comfortable eye relief.

Kowa TSN-773 77mm PROMINAR XD Spotting Scope (Angled Viewing, Requires Eyepiece)

The Kowa TSN-773 77mm PROMINAR XD Spotting Scope with Angled Viewing is a scope of world-class caliber that redefines the standards of color brilliance, detail sharpness, and edge-to-edge brightness. Logically tailored to the most demanding outdoor enthusiast, every technical and ergonomic detail that went into the development of the TSN-770 and 880 series spotting scopes has been examined, perfected, or completely reinvented.

This version uses an element of XD (extra-low dispersion) glass in its construction, which greatly minimizes chromatic aberration. This greatly enhances the clarity for crystal-clear images and high color accuracy. Use of Kowa's patented C3 multi-coated optics has made it possible to increase image brightness significantly over prior-generation models. The advanced lens system of these scopes achieves minimal to zero chromatic aberration even at higher magnifications, with consistent high image brightness.

The housing is made of magnesium alloy that is designed for maximum durability and lightweight body construction. The result is a compact, ergonomic, and functional design for the die-hard enthusiast who wants only the very best.

C3 Coating
C3 Coating is a highly reflective multi-coating of dielectrics. This allows for a much higher reflectivity than with coatings of silver or optically enhanced aluminum, offering a reflectance of 99% or higher across the entire visible spectrum. Not only does this provide bright and sharp images, but accurate color reproduction is also achieved.

Inner Focus System
The innovative inner focus system decreases image movement when focusing on objects, even single handedly. The focus system has the ability to focus from 16.4' (5 m) to infinity in two quick revolutions of the focus knob, ensuring consistent viewing.

Water and Fogproof
The waterproof housing meets the rigorous standards of JIS Protection Class 7; it is also charged with dry nitrogen gas to prevent fogging.

Choice of Eyepieces
Multiple interchangeable eyepieces are available, including 20x-60x zoom, 30x wide, and 25x LER for total versatility in the field. The eyepiece locking mechanism prevents the eyepiece from falling out or getting lost. Converters allow users to utilize eyepieces from other Kowa spotting scope series.
Quick-aiming sightline aids in object locating.
Sliding sunshade shields unnecessary light and raindrops while providing protection for the front element (which has an 82mm filter thread).
Adaptable to 35mm SLR cameras, digital cameras, and video cameras with optional accessories.

  • Kowa Prominar TSN 773 Spotting Scope Review

    I have been using the Kowa Prominar TSN 773 Angled Spotting Scope since Sept 1st of 2015. During this time I have looked through the spotting scope every day, and some days for many hours at a time. (yes I am still married)
    My first extensive use of the Kowa 773 came in mid September. I spent 5 days hunting elk in Idaho with my bow. The early morning and late evenings were spent spotting elk from long distances, and planning the hunt for the day. During this time I averaged about 2 hours of spotting through the scope each day. My average distance of spotting was about 1 mile. At this distance heat waves, bad air etc, can really impact your ability to pick up animals. I was fortunate that my time of spotting occurred before the heat and in an area with great clean air.

    My second extensive use of the Kowa 773 occurred in early November in the State of Utah. I was helping a friend on a late elk hunt in the Wasatch Mountains. During this time I spent about 1 hour per day looking at elk at distances of about 700-1000 yards. The air again was clean and crisp! On this trip I spent lots of time taking photos through the scope with a Phone Scope. The 5 guys that helped me on this hunt were all very very jealous of my ability to see so clearly, see at such early and late hours, and my ability to take great long distance photos.

    My third extensive use of the scope is happening every day. I spend 30 minutes to 1 hour per day looking through this outstanding scope from my front door. I am lucky to face the mountains in Utah, and I am even more lucky that it is loaded with deer.
    So, in Summary, I am a POWER USER of the Kowa 773 spotting scope .

    Overall Thoughts:
    Like I stated earlier. WOW. The quailyt of this scope in my opinion is second to none.
    -The edge to edge clarity of this scope is outstanding. I share it regularly with those hunting with me, and without exception the comments are always the same. “there is great clarity across the entire view field”
    -The scope, due to the large objective has unreal light gathering capabilities. I spot with people who have Swarovski, Leica, Vortex…, the Kowa 773 is unrivaled in its ability to gather light, when compared to like objective spotting scopes. Great job Kowa!
    -The size of this scope is perfect. I like to rate spotting scopes on the ability to see compared to size. This scope is the clear leader in this area. There is not another scope this small that has the clarity, and overall quality of this scope.
    -Clarity through the zoom range. Let’s be honest, there are spotting scopes out there that work well at 15-25 power, and very few that work well above 30 power. You will be thrilled with the Kowa 773 at any power. I have been using this scope and eyepiece combination at 60 power more than any other scope I have every owned. GREAT JOB again Kowa.

    If you are in the market for a top end spotting scope, you have go to consider a Kowa. The overall quality, clarity, and light gathering is just outstanding. It certainly equals the functionality of the big 3: Swarovski, Leica, and Zeiss. In fact I actually prefer this to my Swarovski scope!
    The claims made about Chromatic aberration reduction are absolutely true. This is a well made, and just an outstanding product:
    What they could do better:
    Get the word out to the hunting community
    Slight improvement in the fine focus wheel is needed, it is still not quite fine enough.
