Despite weighing just 1500g and measuring 365mm (including eyepieces), the new binoculars give birders and outdoor enthusiasts access to a level of detail and clarity normally only found in larger and heavier binoculars.
With a compact and lightweight body and 66mm lens, the TSN-66 Prominar is the perfect tool for those who want to travel light, without compromising image quality when they arrive at their favorite spot. The TSN-66 features several optical designs and clever upgrades previously developed for the latest TSN-88/99 models with large lenses. An improved optical coating and a fluorite crystal lens ensure a high transmission through all wavelengths of visible light and provide an image free of chromatic aberration and negative optical distractions. Kowa's unique KR coating on the front lens actively repels dirt, moisture and dust from sticking to the lens. The body is made from a magnesium alloy and has several of the features that characterize the Prominar series, such as double focusing, double tripod mount and an attachable aiming point. With Kowa's dual focus, it's easy to quickly get a sharp image every time. Fast focus renders the subject detailed with just a few gentle turns, while fine focus provides fingertip feel and ultimate focusing accuracy. The magnesium alloy casing provides not only robustness but also a lightweight design. With a fully sealed outer casing, the binoculars are 100% waterproof and nitrogen-filled, making them impervious to the elements. The front has a 72mm filter thread that makes it easy to attach protective filters and has a smooth rotating sun visor with an improved aiming point to find a subject faster.
The spotting scope is available in two versions, TSN-66A (angled) and TSN-66S (straight). Cross compatibility is a fundamental feature of all Kowa Prominar spotting scopes and the TSN-66 is no exception. The accessory collar and bayonet mount are 100% compatible with the entire Kowa System accessory range, making it a very versatile spotting scope.
