Kowa Spotting Scope Review: A Good Look at the Line-up

Spotting scope, a rugged telescope modified for terrestrial use, serves as one of the most pivotal pieces of gear for every hunter, target shooter, birder, or any observer: to locate, identify and observe the subject. This becomes more important when you need to identify the sex, species, or size of the animals. Where your binoculars will fail, that’s the starting point for a spotting scope.

However, there are numerous brands of spotting scope to choose from, creating a lot more confusion. Professional quality and premium finishing, indeed, are not something that every spotting scope brand will provide.

Kowa, established in 1894, has long been known as one of the best spotting scope manufacturers available all around, making only the best in class scopes for the professional shooter, hunter, or birder. Kowa spotting scopes were officially used in 1964 Tokyo Olympics. And, today Kowa is known as one of the best optic brands for all sorts of uses, even if they’re somewhat obscure. They also have one of the widest ranges of scopes available, producing spotting scopes in 7 different sizes (50mm, 55mm, 60mm , 66mm, 77mm, 82mm and 88mm objective lens). These together for a stellar series of Kowa products, and you can easily avail of them both in angled and straight viewing body.

A Quick Guide to Buying Spotting Scopes

Buying spotting scopes can often become overwhelming, and you will be baffled by their varying specifications. And, the price varies wildly depending on the optical quality and size of the devices.  However, knowing what to expect beforehand can save a lot of your time, money, and energy. Without any further ado, let’s dive into the amazing world of spotting scopes.

Do I really need a spotting scope?

This is undoubtedly a hit and miss issue. Binoculars won’t provide you more magnification than 7-10x. However, a spotting scope promises more magnification and amazing clarity. If you want to find a bird in a large flock, locate a bird in its hiding place, distinguish between different species, spot in target shooting of any range, observe the nature closely, you are certainly not looking for a pair of binoculars, but a spotting scope. Also, digiscoping has been made effortless in case of a spotting scopes.

What are the labeled numbers?

Generally, spotting scopes are labeled with three numbers. The first two will represent the magnification range and the last one will be the size of the front lens. For a 15-60x80 model, you will have a product with zoom magnification of 15-60x, while the front lens will be of 80mm diameter.

Angled or straight spotting scope?

Now that you know you are looking for a spotting scope, you will face another dilemma. Do you need angled or straight spotting scope? You simply cannot say one is better than another. It all depends on your preference and specific requirement. Advantages of angled versions:

  • You can use a shorter tripod for the higher mount point.
  • Better support for spotting nestled birds.
  • Easier to be used by different people of a group

However, there are also several advantages to using a straight version:

  • Beginners can aim easily on one of these.
  • Can easily get the glass on an animal.
  • Easy to glass severe downhill angles.
  • It’ll exert less strain on your neck for level viewing.
  • Can view on the ground or water effortlessly.

Magnification and lens

Magnification and lens size are one of the most vital aspects of a spotting scope’s specifications. The higher the magnification, the closer the object will be in your sight. And, with a larger objective lens, you can capture more detail and better image quality, especially at a higher magnification.

However, please remember that a greater magnification and a larger objective lens will not always deliver the expected optical performance unless you are buying a product of superior quality. So, choosing a spotting scope which is made of top-class materials with a premium finish is more important than to get flattered by misleading advertisements.

The magnification will vary from 15-60x from one model to another, while the diameter of the objective lens can be anywhere between 40-100mm. However, if the quality of the spotting scope is not top-notch, you will see the optical performance dropping off as you magnify more and more, and this is primarily determined by the optical system of the scope.

Also, a flagship product from a top vendor will not always guarantee success because the atmosphere plays a big role in this case. As you look into the distance, the more air you’re looking through and the density, air turbulence, heat mirage, dust, air current will play a big role.


Portability is another important issue while considering buying a spotting scope. Be careful here. If you want to carry your scope in the backpack while traveling or mounting, go with a lightweight and compact version. However, if you buy spotting scope with a larger magnification and objective lens, you will feel the exigency of a tripod. The reason is, you need to steady your optics when magnifying to a great scale.

Is an eyepiece included or not?

Know beforehand whether you spotting scope is coming with an eyepiece or not. Most of the high-performance products will not come with an eyepiece. In that case, you have to buy them separately. However, you will have a lot more flexibility and convenience if you have to buy one. The eyepieces will come in various magnification and wide-angle zoom along with different eye reliefs.

With all this information in mind, let’s have a look at some Kowa spotting scope reviews:
