[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] 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.

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

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

[0.9 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] First set it up on a dark day looking through the window and thought it was ok. Finally had sunny day and got wowed by how sharp the KOWA glass is. At night I could just make out the bands on Jupiter. I want to get the 1.6 extender. Shipping from B&H went perfect.

[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!

[0.9 lb] 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 scope. Clear and sharp to the edges. Lightweight and compact. Some say the body feels cheap as it is a polycarbonate body but this is what makes it lightweight. Flourite glass is amazing! Price is right - much cheaper than Zeiss, Leica or Swaro but performance is on par or better. 15-45x 55mm objective is perfect combination....had a 60x Swaro never used 60x unless conditions were perfect as clarity suffered: And, given the weight, quality of glass, price and how often I went above 50x, Kowa is perfect.

[Black] Great price and fast delivery on this Kowa spotter. I was happy to get the anniversary addition since it is in black vs green finish. Optics are stellar and focus mechanisms are very easy to use. My only complaint on this spotter is the armoring. Not at all nice finish, super rough texture that feels like it will hold dirt and is difficult to clean since it grabs microfiber cloth. I'd love to see Kowa move to something rubberized. That being said the weight vs optical quality is really outstanding here A++.
