Angled spotting scopes are the most common types of spotting scopes on the market. They have a good ergonomic design that eases your portability with the help of adjustable eyepieces for a proper aim adjustment. They are less convenient when you need to quickly scan the surroundings, but are very versatile due to angled eyepieces. The most popular spotting scopes have a 45° angled eyepieces and some provide a 90° angle. After adjusting the focus every individual can look through without changing the aim. Compared to straight spotting scopes that are very convenient when viewing down, angled spotting scopes perform incredibly well when looking skywards, thus saving your neck when observing the birds, mountains, the stars and the moon. Rotating eyepieces are also especially helpful when using them through a window of a vehicle. They are less suitable for youth hunters due to its heaviness and angled design but are very convenient for advanced users in hunting, surveillance, archery, astronomy and other law enforcement applications. They are more stable since you don’t have to extend the legs of a tripod too much thus providing more protection when facing wind and other harsh weather situations. Images are also less shaky and observations for extended periods of time more comfortable. But there are still other important factors that you should take in consideration, such as the size of objective lenses, magnifications and other optical technology such as lens and prism coatings that helps you get the best view-through during long distance observations with spotting scopes.
When it comes to hunting, hunters can use different spotting scopes depending on the type of landscape. In the flatlands and on the fields, they usually prefer straight spotting scopes because it is easier to find a target in their field of view. All they have to do is point the scope in the direction of the target.
Hunting in the mountains is a different story. In the mountains, hunter finds an animal on a mountain slope and then stalk it up the hill. That is when angled spotting scope comes into play. The advantage of the angled spotting scope is that the hunter does not need to overstretch his neck while using it.
Angled spotting scopes can be used without a tripod - the user simply puts the scope on the top of a shoulder bag. The same goes for stalking the animal downhill. It is easier to use and carry spotting scope without the tripod; the hunter leans on a backpack and use it as a tripod.
Unlike hunters, birdwatchers use tripods very often with their spotting scopes. This means that for birdwatching, angled spotting scopes are way more appropriate. Angled spotting scopes can be used with lower and thus lighter tripods. Birdwatchers usually carry a lot of equipment on their trips, so lightweight of tripods is the crucial factor.
Birdwatching is often a group activity that involves larger groups of people participating at the same time. Angled spotting scopes come very handy in these situations. The tripod height is adjusted to the smallest person in the group. The taller participants have to bend forward a bit, and there is no need to change the tripod height.
Some angled spotting scopes have a small external tube (usually made of plastic) attached to the body. When looking through it, it is much easier to point the spotting scope into the exact direction towards the birds.
A lot of people love to take pictures of landscapes or birds they are observing. In order to do that, their phones or cameras need to connect with their spotting scopes. Most of the spotting scopes manufacturers also produce digiscoping equipment for both straight and angled spotting scopes. When it comes to the quality of the material, there is no difference between the two. The only difference is that angled spotting scopes are more compact due to their shorter lengths. This means it is easier to support the digiscoping setup when there is an additional weight of a digital camera or a phone.
For the stability of the whole digiscoping setup, a special supporting rails are used.

Most of the angled spotting scopes have one rotating knob for focusing. The focusing knob is located on the top of the body.
Some more expensive models have a two-piece focusing knob:
Spotting Scope with one rotating knob and Spotting scope with two-piece focusing knob.
On some spotting scopes focusing is done with a unique ring that goes around the entire body. Swarovski is a prime example of this approach. These focusing rings have a bigger diameter. A more prominent knob enables finer adjustments at a constant speed.
Most of the spotting scopes are waterproof and filled with either nitrogen or argon. The only weakness is the bayonet mount for interchangeable eyepiece, which is a part of the most premium angled spotting scopes. More affordable spotting scopes have a fixed eyepiece, which ensures even better protection against water intrusion. Even if the scope comes with an eyepiece as a separate part, it remains waterproofed when assembled. The connection between the eyepiece and the body is well sealed.
Both eyepiece and the spotting scope body are waterproof as standalone units.
The recommendation is to fix the eyepiece somewhere in a dry space and then leave it until the end of use.
Many angled spotting scopes feature one or more small Picatinny rails on the housing. The Picatinny rail has a most common use as a platform for mounting a red dot sight on the spotting scope. A lot of hunters and long-range shooters use this setup for rapid target acquisition with their angled spotting scopes. First, they zero the red dot sight in the center on the field of view. Then they use the red dot sight to point the spotting scope precisely on the observation object.
Red dots are used for different purposes:
