From Kowa web site;- The TSN 3 and 4 PROMINAR models incorporated pure fluorite crystal objective lenses which delivered the brightest, sharpest, and clearest images compared to any other spotting scopes. Even though fluorite is an ideal lens type which has extremely low chromatic aberration (color fringing that appears on the periphery of the images), it is crystal instead of glass and is more difficult to process and polish and is, therefore, more expensive. However, fluorite lenses had to be used to deliver "the world's best viewing characteristics". The TSN 3 and 4 models were the first to have PROMINAR printed on the scope body which had previously been used only as a descriptive name.I'm including an old but very adequate tripod with quick release for free. I use the scope with a manfrotto tripod but I'm hanging on to that as I need it for a camera. The Kowa scopes are very light and brilliant quality so I would suggest that it would be worth investing in a decent tripod (Swarovski or Manfrotto for example) and a stay-on case. However will be well packed using bubblewrap etc. The item "KOWA TSN-4 PROMINAR birding Spotting scope 77mm 20-60x zoom + free used tripod" is in sale since Saturday, May 25, 2019.
