Featured Product: USCAMEL 10x50 BAK-4 FMC Porro Binoculars
Marine binoculars are standard equipment for boats & vessels at sea. For marine binoculars, it is important to have the widest field of view especially when operating in open waters. Field of view describes the image visible horizontally when looking through the binocular, and is measured in feet at a distance of 1000 yards.
The USCAMEL 10x50 Marine Binoculars have a wide field of view specification of 396 feet/1000 yards. When viewing a target at 1000 yards, an area of 396 feet across can be seen. The Porro prism optics provide greater field of view and greater depth perception. A large lens size is also required to increase the brightness of the image in low light conditions.
The combination of 10x magnification & large 50mm objective lens diameter gives a reasonably large exit pupil diameter of 5mm for a bright image. The exit pupil is an important factor for effective viewing under low light conditions. In darker environments out at sea, if the dilated pupil of your eye becomes larger than the exit pupil, you will see a partial image surrounded by darkness. The large exit pupil also allows you to properly view an image even when the motion of the vessel is changing the alignment of your eyes with the binoculars.

Built For Purpose
The USCAMEL 10x50 Marine Binoculars are fully sealed marine grade binoculars with American Military standard MIL-STD-810. Specially designed for nautical use & severe weather conditions, the rugged construction is waterproof, dustproof and fog-proof with IPX7 rating. The durable non-slip rubber armored exterior can withstand various harsh weather environments such as rain, snow, wind, sandstorm, and high humidity.
The inside of the body is filled with nitrogen gas which does not hold moisture. This is a must if you are using the binoculars in high humidity conditions to prevent the inside of the lens from fogging up. The waterproof/floating design also makes them float on water. If dropped into the ocean, the binoculars will rise to the surface and float.
The overall attributes, robustness & versatility of the USCAMEL 10x50 means they are ideal companions for boaters & military personnel, and suitable for many security and search & rescue type applications.
Professional Standard Utility
Designed to have a fixed but really long depth of view, you can use the binoculars without needing any focus adjustments. Instead, they come with dioptic correction rings on each of the eyepieces to calibrate to your eyesight. Once you have set up each of the diopters to match your particular vision for each eye, they require no further adjustments.
These type of marine binoculars uses an always in focus optical system. The optics are designed so that they use your eyes natural ability to focus. Everything from its minimum focusing distance of 20 meters to infinity will be in focus. So they are ready to operate at all times including emergencies and even when having your gloves on. You will be always quick on your feet when tracking fast moving targets.
The USCAMEL 10x50 Marine Binoculars have built-in rangefinder & compass which make them suitable also for terrestrial or wildlife observation. With these binoculars, you can measure the distance or size of the target and determine the orientation using the internal rangefinder scale and directional compass.
The compass has an accuracy of 2 degree and is illuminated by a lighting window. You can activate the built-in lighting in the binoculars by pressing the illumination switch at night to read the graduations on both rangefinder & compass in the dark.
High Quality Optics
The USCAMEL 10×50 BAK-4 FMC Porro Binoculars uses the Porro prism system to provide a broader field of view, with high quality optics for high-contrast, better light transmission & image clarity.
BAK-4 prisms are considered the best type of Porro prism as they are made of superior high density barium crown glass with high refractive index, which provides higher levels of image quality than would a prism assembly of the same type made with BK-7 or K9 glass. The BAK-4 prism gives you a sharp image that has high contrast. The FMC objective lens is coated with multilayer anti-reflection green film that has excellent effects in reducing color variation and increasing light transmittance for a brighter & clearer image.
Greater Viewing Comfort
As outlined above, the USCAMEL 10x50 Marine Binoculars are individual focus binoculars with diopter adjuster on both eyepieces. Each eyepiece is individually adjustable to suit your eyesight. Focus the binocular by rotating the right & left eyepiece until the object is sharp & clear. This type of binoculars are designed to focus on distant objects with a very long depth of view so that they are always in focus & makes them extremely easy to use.
It is also important to have a large eyepiece design as the eyepiece size affects viewing comfort. Having a large eyepiece reduces eye fatigue caused by long-term use. The USCAMEL 10x50 binocular's 23mm eyepieces provide a comfortable viewing experience, with long eye relief distance.
The eyepieces feature rubber fold-down eyecups that can be folded back easily so you can operate the binoculars with your eyeglasses on. It is important to maintain the right distance from the eye to the eyepiece to view a sharp image when wearing eyeglasses. Simply push the eyecups back to retract them inside to maintain the eye relief distance. When looking through your binoculars you can put your glasses directly onto the eyecups, the soft silicone material prevents scratching.
