This limited-edition version of the 45° angled-viewing Kowa TSN-553 15-45x55 PROMINAR Special Edition Spotting Scope is one of only 250 units produced worldwide to celebrate their 125th anniversary. This edition comes in a smart and refined black color instead of the signature green, and with a custom matching black neoprene case. Besides the cosmetic changes made for the anniversary edition, Kowa kept the optics and features exactly the same, so you can be sure you'll get the same impeccable performance.

At less than a foot long, this spotter is the ideal companion wherever you go to glass. It employs the ultra-low dispersion PROMINAR fluoride glass that eliminates chromatic aberrations that, when coupled with the fully multi-coated optics and two-speed focusing mechanism, produce bright and clear tack-sharp high-contrast images with accurate color rendition for an immersive observational experience. The impressive zoom range allows you to take in a wide field of view for general viewing purposes, with the ability to draw subjects in close for more detailed observations. This version of the TSN-553 is configured with the eyepiece set at a 45° angle to the optical tube that places your head in a comfortable viewing position whether you're standing, sitting, or lying prone.

To reduce weight, without sacrificing strength or durability, the chassis is made of a polycarbonate material and wrapped in a slip-resistant armor. Rubberized and textured zoom collar and focus wheel make adjustments fast and easy, even when it's cold and wet or when you're wearing gloves. The optical tube is nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes or environmental conditions. To increase your mounting options, the TSN-553 comes outfitted with both a 1/4"-20 and 3/8"-16 tripod attachment—making it compatible with most photo/video/field tripods, heads, quick release plates, and even window mounts.

125th Anniversary Edition

  • Anniversary edition scope features a special black armor color that stands out for its subdued, refined look
  • Production limited to just 250 units worldwide, with 100 allotted to the USA
  • Each spotter has its own individual special anniversary serial number
  • Special anniversary packaging
  • Custom matching black neoprene stay-on/view-through case that is not available separately

Optical Performance

  • Wide 15-45x magnification range allows user to scan the terrain for subjects with the ability to zoom in and make detailed observations
  • 55mm aperture draws in the light required for low-light use while keeping the overall form factor compact for easy mobility
  • Porro prism optical path eliminates the internal interference that roof prisms experience while producing a rich depth of field
  • Ultra-low dispersion PROMINAR fluorite glass elements eliminate chromatic aberration, which causes halos, astigmatism, and fringing, for improved color rendition and contrast
  • Fully multi-coated optics maximize light transmission through the lens to improve image brightness, color rendition, and contrast
  • 132-foot field of view at 1000 yards on 15x, 69-foot on 45x

Use and Handling

  • 45° angled eyepiece to place the user's head in a comfortable viewing position, whether sitting, standing, or lying prone
  • Two-speed coarse and fine focusing mechanism ensures tack-sharp views for detailed observation and positive identification
  • Integrated aiming sight makes finding subjects fast and easy, so users spend more time observing their subjects than trying to locate them
  • Smooth and precise fine and coarse two-speed focusing mechanism moves through the entire focus range in two turns
  • Rubberized and textured zoom collar and focusing wheel are easy to manipulate in cold and wet weather or while wearing gloves
  • 58mm objective lens filter threads allow the use of special filters, like neutral density or polarizing, to enhance the view, especially in difficult condition like in the snow or near water
  • Twist-up eyecup for comfortable use with or without eyewear
  • 3/8"-16 and 1/4"-20 mount to accommodate most photo, video, and field tripods
  • Long eye relief at all magnifications improves viewing comfort and reduces eyestrain
  • 3.7-1.2mm exit pupil

Construction Details

  • Less than 11" long, the compact design is easy to pack and carry in the field
  • Lightweight and impact-resistant polycarbonate chassis
  • Chassis material is temperature resistant, preventing the expansion and contraction that is common with metal, which can cause the optical components to move out of alignment over time and prevent sharp focus
  • Nitrogen filled, IPX6-rated to be waterproof and resistant to internal fogging when moving through extreme temperature changes and conditions
  • Oil-resistant KR exterior lens coatings makes it easy for dirt, sap, and oil to be cleaned off without smudges or residue
  • Retractable sunshade reduces glare and lens flare and keeps snow and rain off the objective for clearer viewing
  • Extremely lightweight: 28.5 ounces
