10 Best Spotting Scope For Adults 2025 in the United States

The Celestron Regal M2 100ED spotting scope is a solid choice for adults interested in birdwatching or outdoor activities that require clear, detailed views. Its 22-67x zoom magnification offers flexibility, letting you see subjects both near and far. The large 100mm objective lens helps gather plenty of light, which improves image brightness, especially in lower light conditions. Thanks to its premium ED (Extra-Low Dispersion) glass and multi-coated lenses, this scope delivers sharp, true-to-life colors with minimal color distortions. The field of view is about 0.9 degrees, which is typical for spotting scopes with higher magnifications, giving you a good balance between detail and how much area you can see at once. Eye relief and comfort are supported by the rotating tripod mount and the angled eyepiece design, making it easier to use for extended periods. It’s also waterproof and fogproof, so it holds up well in various weather conditions.

On the downside, the scope weighs 5 pounds and is somewhat bulky, which might be a consideration if you plan on carrying it for long hikes or travel frequently. However, it comes with useful accessories like a padded case, lens covers, and even a camera mount for digiscoping, adding versatility. For those seeking a durable, high-quality spotting scope with excellent optics for outdoor viewing, the Regal M2 100ED remains a dependable option, though it is not the lightest choice for portability.

The magnification range from 20x to 60x allows for versatile viewing options whether you're looking at close or distant objects. The multicoated optics ensure bright, high-contrast images with true color reproduction, enhancing the viewing experience. Its ergonomic, lightweight Porro prism design makes it easier to handle during prolonged use, though at 4.1 pounds, it's not the lightest option available.

One of the standout features is its waterproof and fogproof construction, thanks to nitrogen purging and O-ring seals, which makes it reliable in different weather conditions. The built-in sliding sunshade is a practical addition, reducing glare and keeping the lens clean in dusty or rainy environments. The scope's weight and size might be a drawback for those seeking ultra-portability.

The included 20-60x eyepiece offers a versatile zoom range, letting you adjust how close you want to see your subject.

The HD lenses with special fluoride coatings reduce color distortion and provide crisp, high-contrast images, so details stand out clearly. It’s a bit on the heavier side, weighing over 5 pounds and measuring about 12 inches long, which might make it less convenient for long hikes but fine for stationary use from a blind or a tripod. The spotting scope is also designed to handle outdoor conditions, with waterproof and fogproof features, meaning it can perform reliably in wet or humid environments. The twist-in eyecups add comfort for long viewing sessions.

This model has been available since 2008 and is known for its lasting quality.
