Its finally here! We have been waiting for a 66m Fluorite Crystal spotter that uses the 25-60x eyepiece for years! And it does NOT disappoint! For the backcountry hunter, the TSN-66 spotting scope is the perfect balance between performance, weight and functionality. This new spotter from Kowa has the precision and clarity you can expect from their Prominar line of spotting scopes, in a more compact and lightweight form.

Over 70 years of experience went in to building the TSN-66. The TSN-66a/66s PROMINAR models have a 66mm Pure Fluorite Crystal objective lens that offers an image free of chromatic aberration (color blur). Pair that with the dual focus knobs that provide pin point focus with finger tip control. Add our favorite eyepiece, the TE11WZ-2 wide angle 25-60x zoom, and you’ll get the perfect backpack hunters’ spotting scope.  How do we know? We’ve tested it.. and tested it, and tested it. We’ve also done comparisons against the competition. This will be our new go-to spotting scope for backcountry hunting.

Whether you are a new hunter or veteran, the performance of this scope offer a fast and precise immersive glassing experience in a small enough package to keep in your pack for any hunt.
