GMGold Black Wooden Picture Frame, Wood, Lot de 1 NOIR, 10x15 cm

Product Information

Save a few minor details like the variable magnification adjustment slider near the right eyepiece, the overall body shape of this Discovery Gator is very typical to that of your typical compact porro prism binocular, which is mostly a good thing as I find this particular shape comfortable to hold in the hands when using the instrument. As you decrease the power, this widens to a maximum of 4.6° (80m @ 1000 meters / 240ft @ 1000 yards) at 8x power, which has to be said is pretty narrow if you compare them to an average 8x binocular.

By improving the level of light transmittance and reducing unwanted reflections that can cause negative effects like ghosting, the level of Anti-Reflection Lens Coatings is one of the most important things to look for when buying binoculars.

Fully folded, the width of the binocular is 9.2cm (3.6in), fully opened it is 11cm (4.3in). Their height is 6.3cm (2.5in), which once again all on the larger end of the scale for a full compact binocular but nothing excessively so. Comparing a low cost binocular like these with other binoculars that are far more expensive may seem a little unfair at first, but as long as you keep in mind the price difference, it does throw up a few interesting points and can highlight a few of their relative strengths and weaknesses and show where some of your money goes if you choose a more expensive pair of binoculars. As you would expect on a low cost compact, these don't come with a vast array of expensive coatings and things like super high quality extra-low dispersion glass, but because they are a porro prism binocular their prisms have total internal reflection and as such they do not need some of the coatings that roof prism's do to achieve the same quality of image. This is one of the main reasons why you often get a better performance from a low cost porro prism binocular than that of a roof prism one in the same price range. There is no mention in any of their marketing of them being either water or fog proof and so I must assume that they are neither. In this price range, not many binoculars are fully waterproof or fogproof and so this is fairly understandable, but it would be nice to know that they were at least a little "weather proof" - anyway I am sure that they would survive a little light rain, but to be completely safe just make sure that you don't get them really wet in very bad weather.

But other than these minor points, I would say that as you would expect of any Nikon product, they look pretty well made and considering that they have a plastic shell, they still feel fairly solid and robust and in terms of build quality are as good as any compact porro prisms found in this price range. One of the biggest gripes I have had with low cost zoom binoculars that I have tested in the past is that at the higher magnification settings the image appears a little hazy or fuzzy, not matter how much you adjust the focus wheel.

The ocular lens has a diameter of 11mm and the eyecup has an external diameter of 37mm, which are both considerably smaller than what you find on most full sized binoculars, but is about average for a compact. This smaller size and very thin rubber covering mean that they are not the most comfortable eyecups that I have ever used, but any discomfort is only really noticeable when you push them quite firmly against your face.

However, having said that, if ultimate image quality and brightness at a high magnification is not that important to you and you are only looking to be able to identify something at long distance and you need a small lightweight device these most certainly could work for you.

An inch (symbol: in) is a unit of length. It is defined as 1⁄12 of a foot, also is 1⁄36 of a yard. Though traditional standards for the exact length of an inch have varied, it is equal to exactly 25.4 mm. The inch is a popularly used customary unit of length in the United States, Canada, and the United Kingdom. Centimeters to inches formula and conversion factor At 350g (12.3oz), it must be said they are on the heavy end of the scale when compared to most other compacts, they do however still feel very light compared to most standard full sized binoculars. The diopter adjustment like most binoculars is a ring located on the right barrel just under the eyecup and is used to correctly set up and focus the binoculars to your particular eyesight and only really needs to be done once when use them for the first time, unless the setting is moved accidentally or you share your binoculars with someone who's setting is not the same as yours. This is not the case with the Discovery Gator 8-20x25 binoculars and whilst the best image I could achieve after fine tuning the focus wheel was still not quite as sharp at 20x as that which I saw at 8x, it really was not bad at all, which for me is actually impressive for a compact zoom binocular at this price.Whilst I would not expect a low cost binocular like these to have the same build quality as a top of the range pair that costs ten times as much, but I still want them to be tough enough to handle most normal bumps and scrapes and still want them to feel like you have a good quality optical instrument in your hands and not just a toy. They have used BK-7 glass as the prism material. At this price point, BK-7 prisms are quite common, but due to them having a lower refractive index, they have a lower transmittance level and thus the image tends to be less bright and not quite as sharp around the edges as those that are made from BaK-4 glass which is generally the preferred option. Optical Coatings You must be available to accept delivery on the date you have requested, failure to do so will result in paying for a re delivery charge. As you increase the magnification level and zoom in on an object, the FOV reduces even further. However this is not as big a problem as I would suggest the best way to use these zoom binoculars is to have them set at 8x to locate the object that you want to observe and the once you have it in your field of view, you can then zoom into it to get a more detailed view. Caused by chromatic aberrations, the level of color fringing that is observable around the edges of contrasting objects becomes a little more evident at higher magnifications. Even so and especially at lower powers, I feel the amount is more than acceptable for a binocular in this price class and thus I would say these do a reasonably good job of keeping it to a minimum.
