The performance of these binoculars is not ideal, but still, the users get a decent viewing experience by spending a small amount of money. Keep in mind that Prostaff 7s is considered the direct competitor of Prostaff 3s series binoculars.

1- Build Quality
No one likes to spend money on a product that is not actually strong. It is like putting your money at risk. I always recommend you choose binoculars that are very strong and durable. Now, let’s talk about Nikonrostaff 3s and 7s binoculars.
Both of these binoculars are made with rubber armor material which is considered decently strong. But, When you use a Nikon Prostaff 3s binos, you will feel like you have a fragile and delicate device in your hand. The rubber used in the Prostaff 3s is probably not as good as the rubber armor used in the Prostaff 7s series.
Winner: Nikon Prostaff 7s Binoculars.
2- Image Quality
Nikon Prostaff 7s binoculars have phase coated prism whereas the prism of the prostaff 3s binoculars doesn’t have phase coated prism which helps the 7s series binoculars to give you clearer and sharper images without any distortion.
In phase-coated prisms, the manufacturer applies a special coating to the surface of the prism, which corrects phase shifts that can occur as light passes through the prism system. This technology increases the visual quality. Unfortunately, Prostaff 3s lacks phase coating.
Winner: Nikon Prostaff 7s Binoculars.
3- Weight & Size
Weight is also an important factor that plays an important role in providing you with a comfortable viewing experience. Nikon Prostaff 3s series binoculars are lightweight as compared to 7s series binoculars.
Look, when the manufacturer makes a binocular more durable and stronger, the weight of that binocular goes up. Similarly, the 7s series is more durable and strong, and its weight is also high. The weight of Prostaff 3s binoculars is around 550 grams whereas the weight of Prostaff 7s series binoculars is around 650 grams.
Note: The weight difference of 100 grams has a massive impact on the comfort of using them for an extended duration.
As far as the size of these binoculars is concerned, I don’t see any massive difference in them as both are decently sized and easy to carry in hands. In fact, you won’t get tired by carrying them for an extended duration.
Winner: Prostaff 3s Binoculars.
4- Field of View
The field of view is the area that you see through the barrel of binoculars. How wide a view you get while viewing through binoculars is called FOV. Binoculars having wider FOV are considered ideal for hunting. Prostaff 3s binoculars offer a wider field of view of around 360 feet to 380 feet.
On the other hand, the Prostaff 7s series is not very good as their offer FOV is around 310 to 320 feet which is considered slightly below par. If you’re trying to buy binoculars for hunting, I don’t recommend you to go with 7s series binoculars. However, both binoculars are good for birding and other outdoor activities.
Winner: Prostaff 3s Binoculars.
5- Eye Relief
Do you wear glasses due to weak vision? If yes then you must care about eye relief and I suggest not buying those optics which have compromised eye relief. The Nikon Prostaff 3s binoculars have an eye relief of 17 mm which is considered ideal.
On the other hand, Nikon 7s series binoculars don’t come with ideal eye relief, however, you will still get decent eye relief of 15 mm. But I don’t recommend you to go with 7s series binoculars as they are not perfect for those who wear glasses. If you don’t wear glasses, then both binoculars are equally good.
Winner: Prostaff 3s Binoculars.
6- Prism type
Both Prostaff 3s and 7s binoculars come with roof prism type which is very good in providing you with ideal optical performance. But still, there is a difference that makes the 7s binoculars a slightly better option than the 3s binoculars.
The roof prism of 7s binoculars phase corrected which enhanced their visual quality and offered images with better contrast. On the other hand, the roof prism of 3s binoculars is not phase-corrected. You will notice the difference in the optical performance when using them in different lighting conditions.
Winner: 7s binoculars because they have a phase-corrected prism.
7- Performance in low-light conditions
Both of these binoculars offer nice optical performance in daylight conditions. You won’t have any issues using them. However, when it comes to using binoculars in low light conditions, real talk starts about 3s vs. 7s binoculars because they differ.
The 7s binoculars have better lens coating layers on the lenses as compared to the 3s binoculars. Moreover, the roof prism of 7s binoculars is also phase coated which means that you’ll be able to see brighter visuals in low-light binoculars with 7s binoculars.
It is important to note that lowlight usability majorly depends on the size of the objective lens. If you choose a binocular with a bigger-sized objective lens, you tend to see brighter visuals. The reason is that the bigger-sized object captures or gathers more light for processing.
Winner: 7s binoculars offer better low light usability as compared to the 3s binos.
8- Value to Money
Well, it’s hard to announce a value-to-money product as both offer excellent performance. But I am going a bit different way. For me, value to money means that binoculars offer decent visuals and save buyers some bucks. You take that as I am just trying to convey a message.
The 3s binoculars are inexpensive and offer decent performance in different outdoor conditions. I know their optical performance is not ideal – but still, by using them, you’ll be able to see everything clearly which fulfills your needs.
On the opposite side, the 7s binoculars offer ideal optical performance, and you won’t find any issues while using them. But the issue is that the 7s binoculars are expensive and make it hard for the common man to afford. So, I consider 3s binoculars pure value to money binoculars.
Winner: Nikon 3s binoculars are better as they are available at affordable prices.
9- Tripod Adaptability
Tripodadapability is important for those people who have shaky hands or spend too much time using binoculars. When you choose a binocular with tripod adaptability, then you won’t have to carry a binocular in your hands, instead, you will be able to fit them in the tripod stand and start using them.
Nikon Prostaff 7s series binoculars can be fit on the tripod stand. In fact, they can be used by fitting them on the car mount. On the contrary, Nikon binoculars 3s series binoculars don’t have tripod adaptability and you will have to carry them in your hands while using them.
Winner: Nikon Prostaff 7s Binoculars.
10- Pricing and affordability
Budget is one of the most important factors that control the buying decisions of people. Nikon Prostaff 3s binoculars are cheaper and anyone having a very small budget can buy them. However, the performance of 3s binos is not ideal.
Nikon Prostaff 7s binoculars are expensive and you will have to increase your budget size to buy them. When you spend more, you always get more features and better performance. In terms of providing value, Nikon Prostaff 7s binoculars have no match.
Winner: Nikon 3s Binoculars.

End of the day, the choice is yours: however, my aim is to give you clear details of things so that it becomes easier for you to make your final decision. Nikon Prostaff 3s binoculars are very good but they are not perfect.
One thing that I would say is that these 3s series binoculars fall in the budget category and you should not expect too many fancy features in them. In case you have got a tight budget, I recommend you to go with 3s series binoculars and which specification you need depends on your needs.
On the other hand, Nikon Prostaff 7s binoculars are premium and they do have many features that will enhance your viewing experience. However, keep in mind that these 7s series binoculars require a handsome budget.
