Since I use my optics also indoors taking advantage from my window panoramic view, I would like to take the benefit of my 2 eyes resolution instead of one and just had a relaxing moments  scanning the fields and mudflats.Their use on stationary viewpoints like raptor counts, bird hides etc. is also to consider, and I can see their pros when you have to use them for more than 6hours straight!Kowa Higlander PROMINAR is probably a good standart, and although I have never looked trough one, it is probably safe to assume  that they perform like any other Kowa scope maybe even better than the known Tsn823, the later is probably more comparable with Docter Aspectem 80/500ED, wich I have already tried, but both to costly for my wallet...</blockquote>
