How to Buy a Spotting Scope

A spotting scope is a portable, high-powered telescope that is designed specifically for use in the observation of distant objects.

These instruments are often used by birdwatchers, hunters, and other outdoor enthusiasts to get a closer look at animals, landscapes, and other objects that are too far away to be easily seen with the naked eye.

Spotting scopes come in a variety of sizes, shapes, and configurations, and can be mounted on tripods or handheld for easy transport. They are an essential tool for anyone interested in getting a closer look at the world around them.

Here are 5 things to know when you want to buy one:

1. Magnification

The magnification of a spotting scope determines how large an object will appear when viewed through the scope. Higher magnification is generally better, but it also comes with a trade-off in terms of image stability and the size and weight of the scope.

Magnification is an important factor to consider when buying a spotting scope, as it determines how large an object will appear when viewed through the scope. The magnification of a spotting scope is indicated by a number followed by an "x", such as 20x or 30x. The first number refers to the magnification power of the scope, while the "x" stands for "times". For example, a 20x spotting scope will make an object appear 20 times larger than it would to the naked eye.

One of the main advantages of a spotting scope is that it allows you to see distant objects in much greater detail than you could with the naked eye. Higher magnification is generally better for this purpose, as it allows you to see more detail and distinguish finer features of the object you are observing. However, there are some trade-offs to consider when choosing a spotting scope with high magnification.

One of the main drawbacks of high magnification is that it can make it difficult to keep the image steady. Even small movements of the scope or the object you are observing can cause the image to shake or blur, making it difficult to see clearly. This is especially true at higher magnifications, where the image is already greatly enlarged. To mitigate this problem, it is important to use a sturdy tripod or other mounting system to keep the scope steady.

Another consideration when choosing the magnification of a spotting scope is the size and weight of the scope. Higher magnification generally requires larger, heavier lenses, which can make the scope more difficult to transport and use. This is especially important if you plan to take your spotting scope on extended trips or hikes, as a heavy scope can be a burden to carry.

Overall, the magnification of a spotting scope is an important factor to consider when choosing the right scope for your needs. Higher magnification is generally better for seeing more detail, but it also comes with trade-offs in terms of image stability and the size and weight of the scope. Consider your intended use and any potential challenges you may face when using the scope to determine the best magnification for your needs.

2. Objective Lens Size

The objective lens size of a spotting scope determines how much light the scope can gather. Larger objective lenses are generally better, but they also make the scope heavier and more expensive.

Objective lens size refers to the diameter of the front lens of a spotting scope, which is the lens that is furthest from the eyepiece. It is typically measured in millimeters. A larger objective lens size can allow for a larger field of view and more light gathering power, which can be beneficial for low light conditions and long distance viewing. However, a larger objective lens can also make the spotting scope heavier and more difficult to carry around, and it may be more expensive.

One important factor to consider when choosing the objective lens size of a spotting scope is the intended use. For example, if you plan to use the spotting scope for long distance viewing, such as for birdwatching or nature observation, a larger objective lens size may be beneficial as it can provide a clearer, more detailed image. On the other hand, if you will primarily be using the spotting scope for shorter distance viewing, such as for target shooting or sports events, a smaller objective lens size may be sufficient.

Another factor to consider is the magnification of the spotting scope. A larger objective lens size can allow for higher magnification, but it is important to note that increasing the magnification can also reduce the field of view and make the image less stable. It is generally recommended to choose a spotting scope with a magnification that is appropriate for the intended use, rather than focusing solely on the objective lens size.

In addition to the size of the objective lens, it is also important to consider the quality of the lens itself. A higher quality lens with a good coating can improve the overall image clarity and contrast, even in low light conditions. It is generally worth investing in a spotting scope with a high quality lens, as the lens is an essential part of the overall performance of the spotting scope.

Overall, the size of the objective lens is an important factor to consider when choosing a spotting scope, but it should not be the only factor. It is important to consider the intended use, magnification, and lens quality, as well as the weight and portability of the spotting scope.

3. Optical Quality

The optical quality of a spotting scope is determined by the quality of the lenses and coatings used. Higher quality optics will produce a clearer, more detailed image, but they will also be more expensive.

Optic quality refers to the overall performance and clarity of the lenses in a spotting scope. It is an important factor to consider when choosing a spotting scope, as a high quality optic can greatly improve the overall viewing experience.

There are several factors that can affect the optic quality of a spotting scope. One factor is the quality of the lenses themselves. Higher quality lenses are typically made from superior materials and have a more precise shape, which can result in a clearer and more detailed image. Lenses can also be coated with special coatings that can reduce glare, improve contrast, and enhance the overall image clarity. It is generally worth investing in a spotting scope with high quality lenses, as the lenses are an essential part of the overall performance of the spotting scope.

Another factor that can affect optic quality is the magnification of the spotting scope. A higher magnification can allow for a closer, more detailed view of distant objects, but it can also reduce the field of view and make the image less stable. It is generally recommended to choose a spotting scope with a magnification that is appropriate for the intended use, rather than focusing solely on the highest possible magnification.

The size of the objective lens, which is the front lens of the spotting scope, can also affect the optic quality. A larger objective lens size can allow for a larger field of view and more light gathering power, which can be beneficial for low light conditions and long distance viewing. However, a larger objective lens can also make the spotting scope heavier and more difficult to carry around, and it may be more expensive.

In addition to these factors, the overall build quality of the spotting scope can also impact the optic quality. A well-made spotting scope with good seals and a durable construction can protect the lenses and prevent moisture, dust, and other contaminants from entering the scope, which can help maintain the optic quality over time.

Overall, optic quality is an important factor to consider when choosing a spotting scope. It is worth investing in a spotting scope with high quality lenses and a good overall build quality in order to get the best possible viewing experience.

4. Mounting Options

Some spotting scopes come with a built-in tripod mount, while others require a separate tripod or other mounting system. Consider your intended use when choosing a spotting scope to ensure that it is compatible with your preferred mounting method.

Mounting options for spotting scopes refer to the various ways that a spotting scope can be attached to a tripod, vehicle, or other support system. The type of mounting option that is most suitable will depend on the intended use of the spotting scope and the specific requirements of the user.

One common type of mounting option for spotting scopes is a tripod mount. This allows the spotting scope to be attached to a tripod, which can provide a stable platform for viewing. Tripod mounts can be either built-in or removable, and they typically use a standard tripod screw. Some spotting scopes may also come with a tripod that is specifically designed for use with the scope.

Another type of mounting option for spotting scopes is a car window mount. This allows the spotting scope to be attached to the window of a vehicle, which can be a convenient way to use the scope while driving or traveling. Car window mounts typically use a clamp or suction cup to attach the scope to the window, and they may be adjustable to allow for different viewing angles.

There are also specialized mounts available for attaching a spotting scope to a rifle or other firearm. These mounts typically use a dovetail or Picatinny rail system to attach the scope to the gun, and they may be adjustable for windage and elevation. It is important to ensure that the spotting scope is properly secured and balanced when using a firearm mount, as the recoil from the gun can affect the stability of the scope.

In addition to these options, there are also adapters available that allow a spotting scope to be attached to other types of support systems, such as a monopod or a ball head. These adapters can be useful for users who want to be able to use their spotting scope in a variety of different situations.

Overall, there are a wide range of mounting options available for spotting scopes, and the most suitable option will depend on the intended use and the specific requirements of the user. It is important to choose a mounting option that is appropriate for the spotting scope and that provides a stable, secure platform for viewing.

5. Water and Fog Proofing

If you plan to use your spotting scope in wet or humid conditions, it is important to choose a scope that is water and fog proof. Look for a scope with a high level of water and fog resistance to ensure that it will perform well in these conditions.

Water and fog proofing refer to the ability of a spotting scope to be used in wet or humid conditions without being damaged or impaired. These features are important for outdoor enthusiasts who may encounter a wide range of weather conditions while using their spotting scope.

There are several ways that a spotting scope can be made water and fog proof. One way is through the use of seals and gaskets that prevent moisture from entering the scope. These seals can be found around the eyepiece, the objective lens, and any other openings in the scope. It is important to ensure that the seals are in good condition and properly positioned in order to provide effective protection against moisture.

Another way that a spotting scope can be made water and fog proof is through the use of a nitrogen or argon purging system. These systems remove the air from inside the scope and replace it with an inert gas, which helps to prevent moisture from forming on the inside of the lenses. Nitrogen and argon are commonly used for this purpose because they do not react with other materials and they do not condense at low temperatures.

In addition to seals and purging systems, a spotting scope can also be made water and fog proof through the use of high quality materials and a durable construction. A spotting scope with a sturdy, well-made body and high quality lenses can withstand exposure to moisture and other elements, helping to maintain its performance and overall lifespan.

It is worth noting that no spotting scope is completely water and fog proof. All spotting scopes are given an "ingress protection" rating, or an IP rating, which indicates the level of protection they offer against moisture and other contaminants. The higher the IP rating, the more protection the spotting scope has. For example, a spotting scope with an IPX7 rating is protected against temporary immersion in water, while a spotting scope with an IPX8 rating is protected against continuous immersion in water. It is important to choose a spotting scope with an appropriate IP rating for the intended use.

Overall, water and fog proofing are important features to consider when choosing a spotting scope, especially for outdoor enthusiasts who may encounter wet or humid conditions while using their scope. These features can help protect the scope and maintain its performance in a wide range of weather conditions.
