Buying Guide for the Best Pocket Monocular
Choosing the right pocket monocular can greatly enhance your outdoor experiences, whether you're bird watching, hiking, or attending a sports event. A pocket monocular is a compact, lightweight optical device that allows you to see distant objects more clearly. When selecting a pocket monocular, it's important to consider several key specifications to ensure you get the best fit for your needs. Here are the main specs to look at and how to navigate them.MagnificationMagnification refers to how much closer an object appears when viewed through the monocular. This is usually represented by a number followed by an 'x', such as 8x or 10x. Higher magnification means you can see objects more closely, but it can also make the image shakier and harder to stabilize. For general use, a magnification of 6x to 8x is often sufficient, providing a good balance between image clarity and stability. If you need to see very distant objects in detail, you might opt for 10x or higher, but be prepared for a potentially shakier image.
Objective Lens DiameterThe objective lens diameter is the size of the front lens, measured in millimeters. This spec is important because it determines how much light the monocular can gather, which affects image brightness and clarity. A larger objective lens (e.g., 25mm or 30mm) will provide a brighter image, especially in low-light conditions, but it can also make the monocular bulkier. For a pocket monocular, a lens diameter of 20mm to 25mm is usually a good compromise between portability and image quality.
Field of ViewField of view (FOV) is the width of the area you can see through the monocular, usually measured in feet at a distance of 1,000 yards. A wider field of view allows you to see more of the scene without moving the monocular, which is useful for tracking moving objects or scanning large areas. If you plan to use the monocular for activities like bird watching or sports events, look for a wider FOV. For general use, a field of view of around 300 to 400 feet at 1,000 yards is typically sufficient.
Weight and SizeSince you're looking for a pocket monocular, weight and size are crucial factors. A lighter and more compact monocular is easier to carry around and use for extended periods. Look for a monocular that weighs less than 10 ounces and is small enough to fit comfortably in your pocket or bag. However, keep in mind that very small and lightweight models might compromise on some optical performance aspects, so find a balance that works for your needs.
Lens CoatingLens coating refers to the special coatings applied to the lenses to reduce glare and improve light transmission, resulting in clearer and brighter images. There are different types of coatings, such as fully coated, multi-coated, and fully multi-coated. Fully multi-coated lenses offer the best performance, providing the brightest and clearest images. If you plan to use your monocular in various lighting conditions, investing in a model with high-quality lens coatings is advisable.
Waterproof and FogproofWaterproof and fogproof features are important if you plan to use your monocular in different weather conditions. Waterproof monoculars are sealed to prevent water from entering, while fogproof models are filled with nitrogen or argon gas to prevent internal fogging. These features ensure that your monocular remains functional and provides clear images even in rainy or humid conditions. If you enjoy outdoor activities regardless of the weather, look for a monocular with these protective features.
