First Impression Of The Gosky 10×42 Binoculars

Behold, a marvelous artifact has been presented before us! The initial impression of the binoculars is exceptionally promising, indeed. The instrument is fashioned to be compact, lightweight, and highly ergonomic to hold, for the rubber-armored housing affords a fine grip.

It is noteworthy that the Gosky binoculars’ housing is crafted from polycarbonate plastic, a material possessing the dual attributes of being lightweight and impervious to damage. However, it is regrettable that the housing is not O-ring sealed, thus rendering it incapable of achieving waterproofness. Nonetheless, the rubber cover does grant a degree of water resistance. Therefore, it could endure modest rainfall, but if it is unfortunate enough to plunge into the water, it shall not emerge unscathed.

One particular feature that the binoculars do possess is a tripod adapter connection. Moreover, it is fascinating to observe that the binoculars alone, bereft of their accompanying strap and lens cover, weigh less than 20 ounces. Consequently, among the 10 x 42 binoculars, this specific device qualifies as a true lightweight contender.

Lo and behold, a marvel of optical engineering has graced our presence! The hinge of the barrel bridge is a symphony of smooth, fluid motion, and nary a hint of wobbling can be detected in its operation.

One noteworthy aspect of this device is the center focus wheel, which can be manipulated to turn one and a half rotations, thereby enabling a vast range of adjustments, from near to infinite. Such a feat is accomplished with exceptional ease and uniformity, and the wheel itself is endowed with a sizeable diameter that would enable even a gloved hand to manipulate it without impediment.

The eyecups, whilst they may only offer a modest quarter-inch of adjustability, are sufficient to accommodate the demands of short eye relief. It is lamentable, however, that no explicit values are provided for the diopter compensation. Nonetheless, it is my humble conjecture that such compensation hovers between the range of 1 to a maximum of 1.5 diopters.

Optical Performance

Gaze in wonder upon these splendid binoculars, possessing specifications of the 10 x 42 variety, which are renowned for their versatility and flexibility. The magnification power of 10 times is ideal for handheld binoculars, and it permits the viewer to behold the minutiae of distant objects in exquisite detail. Even the elusive form of a petite avian creature may be perceived with great clarity and identified with ease, thanks to the impressive magnification capability of these binoculars.

Moreover, the combination of the 10-fold magnification and the capacious 42mm objective lens renders the exit pupil an ample 4.2mm in width. This attribute is highly advantageous for viewing objects in low-light conditions, such as the subdued luminescence of twilight. However, it is vital to note that the quality of the prisms and the lens coatings could further augment the low-light performance of the binoculars, thereby enhancing the viewer’s overall experience.

Lens Coating

Marvel at the technical expertise of the manufacturer, who, according to their assertion, has meticulously coated the lenses with a layer of multifaceted glory, thus enabling the device to transmit light with enhanced proficiency. Such an attribute proves to be a valuable asset for those who intend to utilize the instrument in low-light scenarios, where the ability to discern details with precision is paramount.

Additionally, when one takes a peek at the objective lenses, one will bear witness to the marvel of light-management technology. The interior walls of the binoculars have been graced with a coat of velvety darkness, which serves to reduce the occurrence of stray light and undesirable reflections. It is a sight to behold!

Indeed, even when held up to the light and basked in the warm glow of illumination, the lenses reflect a gentle, yet striking, bluish-green tint, which serves as a testament to their technical prowess. Such an effect further enhances the viewing experience of the observer, imbuing their visual perception with a sense of heightened vividness and detail.


Behold the beauty of the Gosky 10×42 binoculars as they are held aloft by outstretched arms, their magnificence basking in the glory of the light. Observe with wonder the exquisitely round and even exit pupil that graces the viewer’s line of sight. This attribute, my dear friend, is a hallmark of the wondrous BaK4 glass prisms that these binoculars possess.

It is well known that the BaK4 glass prisms are superior to their Bk7 counterparts, exhibiting better optical performance and enhancing the viewing experience of the observer in ways beyond compare. The promise of such quality is not to be taken lightly, for it imbues the device with a sense of technical superiority and elevates it to a level of excellence that is truly remarkable.

Eye Relief

Lo and behold, let us delve into the intricacies of eye relief, a topic of great importance when discussing binoculars. The eye relief of the esteemed device in question measures a mere 12 millimeters, a distance that cannot be deemed lengthy by any means. As a person of normal sight, I find this to be quite satisfactory and not a cause for concern. However, for those who require glasses when using binoculars, this may pose a considerable issue.

Alas, the struggle of those with poor eyesight is one that cannot be ignored. The 12-millimeter eye relief may not provide the necessary distance to accommodate the glasses-wearing observer, thereby detracting from the fullness of their viewing experience. It is a matter that requires attention and consideration, for the pleasure of viewing should not be limited by one’s visual impairment.

Close Focus

At close range I was able to observe at about 12 feet, the image appeared sharp and in focus. Viewing in the close range below 20 feet is exhausting because the collimation leaves something to be desired. But this is a well-known problem in inexpensive roof prism binoculars. In this case, it is better to close one eye and observe monocularly.


To ensure a comfortable viewing experience without eye fatigue or double images, it’s essential for the optical axes of both binocular tubes to run parallel to each other. This precise alignment, also known as collimation, can be lost if the binoculars are dropped or if the barrel hinge bridge is damaged. Therefore, it’s advisable to check the collimation regularly, particularly for inexpensive binoculars as manufacturers may only quality control a fraction of their production.

To perform a collimation check, simply aim the binoculars at a distant object, focus, and then alternate opening and closing each eye. Both eyes should see the same image section without jumping or the horizon bouncing vertically. With the Gosky 10×42 binoculars tested here, the collimation was generally satisfactory except for some issues at close range.

Edge Sharpness And Edge Blurring

The visual impression through the Gosky 10×42 binoculars is satisfactory. The image is well-defined and focused at the center. As you move toward the edges, however, the sharpness gradually fades away, and there is a slight increase in edge blur. Despite this, considering the price point of this instrument, which is under 100 dollars, there is little to grouse about as the main field of view (the middle 50% of the view) retains its sharpness.


As a result of the way lenses magnify objects, distortion is often present, and it may vary from the center to the edges of the image. However, when observing stationary objects using the Gosky 10×42 binoculars, distortion is not an issue. But as soon as the instrument is slowly panned across a power pole or the edge of a house wall, a slight pincushion distortion can be observed at the upper and lower edges of the field of view, which is typically based on optical laws.

Color Fidelity

During the visual examination of trees, landscapes, and natural scenery through the Gosky 10×42 binoculars, colors appear to be in their natural and original states. When directing the binoculars to a white house wall under a clear blue sky, no difference in color is noticeable. The house wall appears to be in the same white hue, except for a very slight bluish tint, which could hardly be noticed by the naked eye.

Chromatic Aberration/Color Fringing

Affordable binoculars may display color fringing to a greater or lesser extent at the borders between light and dark contrasts. Similarly, this is observable in the Gosky Roof Prism Binocular, which is comparatively budget-friendly.

Upon conducting normal daylight observation, a feeble but recognizable color fringing can be seen both across and lengthwise at high-contrast transitions. However, this is minimal and satisfactory for an economical model.

Advantages Of Gosky 10×42 HD Roof Prism Binoculars

The Gosky Roof Prism Binocular is an optical instrument that appears aesthetically pleasing, with a tough and durable build that feels great in the hand. The rubberized exterior ensures a secure grip and provides sufficient protection against potential knocks and bumps.

With a 10x magnification and an approximate field of view of 107 meters, the binoculars allow for a detailed examination of far-off objects, making it ideal for outdoor exploration and wildlife observation.

The 42 mm objective lens, combined with the BAK 4 roof prisms, generates vivid and high-contrast true-to-life images, even in low-light conditions.

Furthermore, the lightweight construction of just 20 ounces makes it a portable option that won’t weigh you down during long excursions.

The package includes several handy accessories like a neck strap, carry case, lens and eyepiece covers, and a microfiber lens cleaning cloth. The added bonus of a smartphone mount, which is compatible with most smartphones, is a particularly convenient feature.

Disadvantages 0f The Gosky 10×42 Binoculars

The ocular distance of a meager 12 mm may satiate the needs of individuals with unperturbed eyesight, but those afflicted with vision defects necessitating glasses, and who also utilize binoculars, shall find the Gosky 10×42 binoculars an imposing and Herculean task.

Alas! One must be cognizant of the limited capabilities of this contraption in the face of capricious weather conditions, considering the dearth of O-ring sealing, thereby rendering the Gosky 10×42 binoculars suitable only to a confined extent.

It must be conceded that the color and shape distortions identified in this equipment fall squarely within the normative range characteristic of budget binoculars. However, it must be emphasized that these flaws, while detectable, only manifest themselves in a feeble and lackluster manner, requiring only the utmost fastidiousness in the discernment of the most conspicuously differentiating light-dark demarcations. It is worth noting, though, that the majority of users will remain oblivious to these defects during routine usage.

Using The Gosky 10×42 Binoculars

Whether your pursuits lead you to the untamed expanses of nature, or the bustling heart of the city, the Gosky 10×42 binoculars, faithful to their task, faithfully render the viewed objects in a clear and vivid fashion.

Alas, when contending with the vagaries of difficult light conditions, or gazing towards certain angles or in the direction of the sun (an endeavor to be scrupulously avoided), the field of vision of the Gosky 10×42 binoculars shall betray a feeble light scattering and a vexatious reflection.

Let it be noted, however, that optimal viewing comfort is obtained when properly centering the Gosky 10×42 binoculars before one’s ocular organs. A shadowing towards the edge of the field of view (referred to as “kidney beaning”) may otherwise ensue.

The act of rapidly transitioning between objects of varying distances is facilitated by the expeditious and facile focusing mechanism of the Gosky 10×42 binoculars.

In sum, little can be faulted about these utilitarian instruments, for they prove to be convenient and user-friendly while delivering an impressive optical performance that belies their budget-friendly price point.


So Are Gosky Binoculars Good?

The Gosky 10×42 HD Roof Prism Binoculars, priced within the budgetary constraints of the occasional or neophyte user, are well-suited to meet their needs. However, those of an expert or professional caliber may take umbrage with the slight chromatic and spherical aberrations, along with the attendant edge blurring. Such defects may elude detection by the majority of users, though.

Regrettably, individuals dependent upon visual aids, necessitating their usage whilst peering through binoculars, may experience disappointment with the Gosky 10×42 binoculars, finding them wanting in the eye relief department. Alternatives boasting lengthier eye relief may better serve their needs.

Conversely, if one’s intent is to procure an economically viable pair of binoculars for beginners, characterized by commendable optical performance when deployed in avian observation, hunting, hiking, or any manner of outdoor activities, the Gosky 10×42 Roof Prism Binoculars warrant earnest consideration.
