Buying Guide for the Best Spotting Scopes
Choosing the right spotting scope can greatly enhance your outdoor experiences, whether you're birdwatching, hunting, or simply enjoying nature. Spotting scopes are designed to provide high magnification and clear images of distant objects. To find the best fit for you, it's important to understand the key specifications and how they align with your needs. Here are the main specs to consider when selecting a spotting scope.MagnificationMagnification refers to how much larger an object appears through the scope compared to the naked eye. This is important because higher magnification allows you to see more detail. Spotting scopes typically offer magnification ranges from 15x to 60x. Lower magnifications (15x-30x) are easier to use and provide a wider field of view, making them ideal for scanning large areas. Higher magnifications (30x-60x) are better for detailed observations but can be harder to stabilize and may require a tripod. Choose a magnification range based on your primary use; for example, birdwatchers might prefer lower magnifications for easier tracking, while hunters might opt for higher magnifications for spotting game at long distances.
Objective Lens DiameterThe objective lens diameter is the size of the front lens of the spotting scope, measured in millimeters. This spec is important because a larger objective lens allows more light to enter the scope, resulting in brighter and clearer images, especially in low-light conditions. Common sizes range from 50mm to 100mm. Smaller lenses (50mm-60mm) are more compact and lightweight, making them easier to carry, but they may not perform as well in dim light. Larger lenses (80mm-100mm) provide better image quality and brightness but are bulkier and heavier. Consider where and when you'll be using the scope; if you need portability, go for a smaller lens, but if image quality is your priority, a larger lens is better.
Field of ViewField of view (FOV) is the width of the area visible through the scope at a given distance, usually measured in feet at 1,000 yards. A wider FOV allows you to see more of the landscape at once, which is useful for tracking moving objects or scanning large areas. Narrower FOVs provide more detail but limit the visible area. FOV is inversely related to magnification; higher magnifications result in narrower FOVs. If you need to observe fast-moving subjects or scan wide areas, choose a scope with a wider FOV. For detailed observations of stationary objects, a narrower FOV is sufficient.
Eye ReliefEye relief is the distance from the eyepiece to your eye where you can still see the full field of view. This is important for comfort, especially if you wear glasses. Longer eye relief (15mm or more) is more comfortable and allows you to see the entire image without straining your eyes. Shorter eye relief can make it difficult to use the scope for extended periods. If you wear glasses, look for scopes with at least 15mm of eye relief. For those without glasses, shorter eye relief may be acceptable, but longer eye relief is generally more comfortable for everyone.
Lens CoatingsLens coatings are applied to the glass surfaces to reduce glare and improve light transmission, resulting in clearer and brighter images. There are different levels of coatings: coated (a single layer on at least one lens surface), fully coated (a single layer on all air-to-glass surfaces), multi-coated (multiple layers on at least one lens surface), and fully multi-coated (multiple layers on all air-to-glass surfaces). Fully multi-coated lenses provide the best image quality and brightness. If you need the best possible image clarity and brightness, opt for fully multi-coated lenses. For casual use, lower levels of coating may be sufficient.
Waterproof and FogproofWaterproof and fogproof features protect the scope from moisture and internal fogging, which can occur due to temperature changes. These features are important for outdoor use in various weather conditions. Waterproof scopes are sealed to prevent water from entering, while fogproof scopes are filled with nitrogen or argon gas to prevent internal fogging. If you plan to use your spotting scope in wet or humid environments, or if you expect to encounter significant temperature changes, look for models that are both waterproof and fogproof to ensure durability and clear viewing.
Body DesignSpotting scopes come in two main body designs: straight and angled. Straight scopes have the eyepiece in line with the objective lens, making them easier to use for viewing objects at or below eye level. Angled scopes have the eyepiece set at an angle (usually 45 degrees) to the body, which can be more comfortable for extended viewing sessions and for sharing the scope with others. Choose a straight scope if you plan to use it primarily for viewing objects at eye level or if you need to quickly acquire targets. An angled scope is better for prolonged use, especially if you need to look up or down frequently.
