Delta Optical Discovery 16x50 Binoculars
The Delta Optical Discovery 16x50 binoculars are built for people who need a reliable optical instrument in demanding conditions - whether on a hunting stand, a mountain trail or a wildlife watching session. The aluminium body has a rubber-armoured surface that absorbs knocks and handles rough weather well. At just 848 g, the binoculars remain light enough to carry on a full day out without weighing down your bag or neck. Objective and eyepiece covers are included on a strap, so you can access the optics quickly while keeping them protected.
Clear images even in low light
The 50 mm objective lens gathers a solid amount of light, which makes a real difference in reduced visibility - at dusk or inside dense woodland you will see noticeably more than with smaller binoculars. All lenses carry a multi-coated (MC) anti-reflection coating that reduces unwanted reflections and improves colour contrast across different lighting conditions. The relative brightness index of 9.6 confirms the instrument performs well in dim conditions. A field of view of 72 m at 1,000 m and a real angle of view of 4 degrees give you a broad, clear picture of the scene, so you are unlikely to lose track of your subject.
Waterproof and fog-proof construction
The tubes are nitrogen-filled, which prevents internal fogging when temperatures change suddenly - moving from a cold car into a warm room or getting caught in rain will not affect the view. The waterproof housing protects the instrument even in heavy rain or accidental contact with water. The Delta Optical Discovery 16x50 also offers dioptre correction from -4 to +8 dioptres, so users with common vision correction needs can observe comfortably without glasses. The minimum focusing distance of 8 m lets you focus on relatively close subjects, which is particularly useful for birdwatching in natural settings.
