These premium compact binoculars use Canon bright L-series optics to deliver superb, focused, high-clarity images in tough and harsh environments. Your subject will appear 10x closer and brighter thanks to the large exit pupil, making them great binoculars for stargazing. Meanwhile, the resilient, metallic outer layer is certified to keep water out while immersed for up to 90 minutes which makes them great for use as marine binoculars too. These bright binoculars use an optical Image Stabilizer that will keep the image still even while observing your subject from a moving vehicle. Finally, reduced eye strain is promised by the 16mm eye relief.Certified to keep water outFully waterproof metallic coating prevents water molecules from entering the binoculars for up to an hour and 30 minutes when fully immersed. Certified to JIS 7 standardsSteady image even from a moving vehicleCanons binocular Image Stabilizer (IS) technology uses the same principle as the technology used in our EF lenses
