Last month the 550 once again received top honors in a third independent scope review. At a mere 28 ounces, it easily & consistently tops the field as the best compact scope. However, the performance was compared favorably to the industry's most expensive 65 mm spotting scope models (costing >2x and weighing >3x more). National Audubon Society ranked this the best performing scope under $2,000 dollars in their review and Backwoods Pursuit wrote "super compact in size, light as a feather, but most of all, gives you an uncompromising image in a small package" suggesting it as the perfect solution for consumers wanting the best lightweight performer! So don't let the size fool you. Find out what all the fuss is about yourself, & see the Kowa TSN-550 series spotting scopes at a Kowa dealer near you & take advantage of these unprecedented savings!

Product Highlights

  • Straight-Through Viewing
  • 15-45x Zoom Eyepiece
  • 55mm Objective Lens
  • Ultra Low-Dispersion PROMINAR Glass
  • Porro Prism Optical Path
  • Fully Multi-Coated Lenses

The Prominar 553 and 554 feature Pure Fluorite Objectives like the 880 series in a 55mm package with integrated zoom eyepieces. More compact, lighter and brighter than anything in its class! 

At less than a foot long, the straight-through viewing Kowa TSN-554 15-45x55 Spotting Scope 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-550 is configured with the eyepiece set in-line with the optical tube for straight-through viewing to make acquiring subjects easy and tracking moving subjects fast.

To reduce weight, without sacrificing strength or durability, the chassis is made of a polycarbonate material and wrapped in a slip-resistant armoring. A rubberized and textured zoom collar and focus wheel make adjustments fast and easy, even when 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-554 comes outfitted with both a 1/4"-20 and 3/8"-16 tripod attachment — making it compatible with most photo, video, and field tripods on the market.

    Highly recommended.
    I recently purchased a Kowa TSN-554, with Neoprene case and hand support. It has proven to far exceed my expectations. I purchased it primarily to be a more convenient option to scope with a window mount as I have a TSN -99, which is a bit large for that application. It fills that role well and is easily hand held, which makes it fantastic to carry when hiking with minimal gear. As far as optics go, I have the luxury of comparing to Kowa’s flagship spotting scope. It does not disappoint in the least. There are obvious advantages to the 99 due to magnification and objective lens size, but the image quality of the 554 is in the same league as its big sibling. I am simply amazed that such a compact and portable scope delivers so much. Highly recommended.
