Kowa Introduces 99mm Objective Prominar Spotting Scope
Bigger is normally better — when it comes to light transmission and field of view. Kowa has introduced an all-new, high-end spotting scope, the TSN-99 Prominar, which has a huge 99mm front objective lens. This 99mm spotting scope features a pure Fluorite XD (eXtra-low Dispersion) lens for maximum light transmission, with superior edge-to-edge sharpness, and minimal chromatic aberration.
The TSN-99’s primary TE-11WZ II eyepiece provides a 30-70X range of magnification and there is also a 40X extreme-wide-angle eyepiece. That would be very effective for wind-reading. Existing accessories for Kowa’s 88/77 series are compatible with the new TSN-99 series spotters.
Who needs a spotter this big? We expect this will be popular with wind coaches and shooters involved in the ELR game. And guys who started with a 60mm, then graduated to an 80mm or 88mm, may decide to step up to this big new optic. It will certainly offer better low-light performance. That 99mm objective equals 3.898 inches.
With a 100% magnesium alloy structure, this big spotter is lighter than you might expect. The angled model weighs 3.99 lbs. (1810 grams) while the straight version weighs 4.04 lbs. (1835 grams). With the magnesium body, Kowa claims the TSN-99 series is “one of the most compact and lightweight in its class … making it more portable than many other models.” The objective lens boasts a protective Kowa KR coating which actively repels dirt, moisture and dust.
Avaliable accessories include: TE-11WZ II 30-70X wide zoom eyepiece, TE-80XW 40X extreme-wide-angle eyepiece, TSN-EX16 1.6x extender, plus Digiscoping adapters.
The TSN-99 PROMINAR spotting scopes will be available for pre-order starting August 2, 2021, with product distribution beginning on September 9, 2021.* Click HERE for product information.

Kowa’s 88mm TSN-880 Prominar spotters have finished at the top of many spotting scope comparison tests, so we expect the new 99mm TSN-99 to raise the bar even higher. Kowa explains: “The TSN-99 Prominar Series is the evolution of over six decades of Japanese optical design and technology. It utilizes the very best from our optical heritage and benefits from features, technology, and engineering developed by generations of Kowa optical experts.”
Kowa states that the TSN-99 Prominar Spotter was created to deliver “the brightest and widest view of nature[.] We created TSN-99 PROMINAR series because we wanted to deliver one of the most immersive and detailed views of the natural world.”

TE-80XW Extreme-Wide-Angle 40X EyePiece: 37M at 1000M
Along with a 30-70X zoom eyepiece, Kowa offers the Kowa TE-80XW eyepiece for the TSN-99 spotter series. The TE-80XW offers an 80-degree view, one of the widest field of views ever offered with similar magnification. This provides a view of 37 meters (40.5 yards) width at 1000m distance. That would allow you to see a very long line of targets or wide spread of wind flags with 40X magnification.
The TE-80XW incorporates a field-flattener lens maintaining flat resolution throughout the entire 80-degree field of view. The Kowa TE-80XW is 100% waterproof, sealed against the elements, and protected against dirt, moisture and dust by Kowa’s unique KR coating.
*The September 9, 2021 date was in Kowa’s official press release. However, Kowa’s global website states: “The new TSN-99 PROMINAR spotting scope series… will be available to purchase from Kowa authorised dealers from the 1st October 2021 [sic].” Thanks to EdLongRange for finding TSN-99 Series current pricing.
