AFFORDABLE NIGHT VISION

摘要

Many of us have kicked around the idea of buying a night vision system but have been put off by the price. But Bushnell may have a deal for you within its Stealth View product lineup. If you can live with a monocular unit and don't need military-level technology, the Nightwatch unit might be the way to go. It uses active rather than passive infrared illumination, so a human subject could conceivably figure out what you're up to. If your objective is general security and surveillance, cave exploration, night fishing and boating, wildlife observation, or just fooling around, that shouldn't be a problem either.
