[Black] I use this scope for birdwatching. I did not purchase this scope because I was unhappy with the quality of my 82mm scope. I purchased it to have a scope that is less than 1/2 the weight of a full size scope. When going on a hike where reducing the overall weight is a prime consideration, this scope fills the bill. There is no compromise in image quality. If you are looking to reduce weight in your equipment, this scope could definitely be your answer.

[0.93 lb] This stope is very sharp, small and light weight. We will use it to view wolves and bears in Yellowstone as well as the birds near our home. It is easy to use and the cover protects it nicely. Highly recommended.

[Black] We are very pleased with the quality of this item. Our experience with B&H was very positive.

[Black] High quality optics in a lightweight portable package. I am very impressed with the quality of this product. Construction is first rate and very solid with good ergonomic features. The optics are amazing with no color fringing or distortion. I use the scope with a KOWA TSE-Z9B 20-60x eyepiece, another quality item. I am amazed every time I use this scope at the distances I can see, with such detail! I can spend hours looking through the scope enjoying all the detail that has been hiding in plain sight. You can even get photos using and iPhone held up the eyepiece The image is surrounded by a black circle but the detail is amazing. I would recommend the CNW-10 Kowa Cordura Carrying Case. The case is great and is very fast to open and offers protection from bumps and scrapes. You will also need a solid tripod and head as any vibration is easily seen at the high magnification this scope is capable of.

[Neoprene] Product received as advertised and in a very timely manner. We recommend and will use again.

[0.93 lb] I have the sibling, angled version, of the TSN-664M and decided that for certain applications, this straight viewing model was something I needed to have.


It seems at this time the TSN-664M and 663M are being phased out for a new model. I am hopeful this line won't go the way of the Dodo. I think Kowa is a premier spotting scope manufacturer, and this model is a great way to get into a premium spotting scope. My preference is the 30x wide-angle eyepiece. It is super comfortable for long-term viewing especially if you wear glasses.


You can't go wrong with the Kowa Prominar line.

[Black] This is the best Spotting scope I have owned! It is replacing one that cost almost double last year. The Kowa is crystal clear to the edge and is great in low light conditions. I went with a straight 30x eye piece and couldn't be happier. I use the spotting scope on back country hunts because it is light weight and an unbelievable piece of glass. I will be adding more Kowa to my list of fine optics.

[Black] Great spotting scope with easy zoom and focus possibilities. Very sharp and clear view even when zooming very close. The possibility to attach your DSLR camera with adapter is great additional feature. B/H had fast and reliable delivery!

[Neoprene] This scope is incredible and for the money it can't be beat. With the excellent TSE-Z9B 20x-60x zoom eyepiece, there is crisp clarity and a wide field of view through out the zoom range. The compact size and weight make it ideal for back country use. The only thing that keeps it from being absolutely perfect is a slight chromatic aberration at 60x cause with a slight blue halo around bright high contrast objects (you can only see it if you actually look for it). A polarizing filter seems to take it away. I would buy it again and recommend it to anyone who asked. As good as any Swarovski of Leica in standard glass at a third the price and two thirds the weight, can't beat it.

[Black] Great light weight scope. Absolutely competes with all the bigger,heavier more expensive spotters. If you are hiking, hunting etc... this is the scope 100%. It is much brighter , clearer and sharper than the size would indicate. If shooting from one spot only and no need for mobility then the bigger scopes do have a slight advantage. This scope clearly shows animals details/rack size points etc... out past 1500 yards easily. At this price point I expected excellence. It has exceeded those expectations. Wonderful optics !!!
