If you’re trying to decide between two popular spotting scope magnifications, you’re probably asking: is the spotting scopes 25-75×85 better than 20-60×80? The answer isn’t a simple yes or no, as it depends entirely on what you plan to use it for. This guide will break down the key differences to help you choose the right tool for your needs.
Is The Spotting Scopes 25-75×85 Better Than 20-60×80
To determine which scope is better, we need to compare their core specifications side-by-side. The main numbers—25-75×85 and 20-60×80—tell us about magnification range and objective lens size. Let’s look at what that really means for you in the field.
Understanding the Numbers: Magnification and Lens Size
The first number pair (25-75 or 20-60) is the zoom range. The second number (85 or 80) is the diameter of the front (objective) lens in millimeters. A larger objective lens gathers more light, which is crucial for image brightness and clarity, especially in low-light conditions.
- 25-75×85: Higher top magnification (75x) and a larger 85mm lens.
- 20-60×80: Wider field of view at low power (20x) with a slightly smaller 80mm lens.
Key Factor 1: Light Gathering and Image Brightness
The 85mm objective lens has a clear advantage here. It captures more light than an 80mm lens. This difference becomes very noticeable during dawn, dusk, or in heavily shaded areas. The brighter image makes it easier to see details and colors.
However, the 80mm lens is still very capable. For most daytime use, the difference in brightness might be minimal to your eye. But if you’re a serious wildlife watcher or hunter who’s out in early mornings, the 85mm model pulls ahead.
Key Factor 2: Magnification Range and Stability
Higher magnification isn’t always better. The 25-75x scope offers more power for extreme long-distance viewing. This can be great for trying to identify a bird on a distant cliff face or reading small writing on a target.
- At 75x, the image is more susceptible to shake, even on a tripod. Atmospheric heat haze can also distort the view.
- The 20-60x scope starts at a lower 20x power. This gives you a much wider field of view, making it easier to locate your subject quickly. It’s generally more stable and user-friendly across its entire range.
Key Factor 3: Size, Weight, and Portability
A larger lens usually means a bigger, heavier scope. The 25-75×85 model will typically be bulkier and weigh more than the 20-60×80. Ask yourself how far you’ll be carrying it.
- For backpacking or long hikes, the smaller 80mm scope is often the more practical choice.
- For stationary use from a blind, a vehicle, or a set location, the extra size of the 85mm scope is less of a drawback.
Best Uses for Each Spotting Scope
Now, let’s match the scopes to specific activities. This is the best way to see which one fits your life.
When to Choose the 25-75×85 Spotting Scope
This scope excels in situations where light gathering and max power are top priorities. Consider it if:
- You do most of your viewing in low-light conditions.
- Your primary goal is extreme long-distance observation (e.g., alpine wildlife, distant shorebirds).
- You use it for long-range target shooting and need to see very small bullet holes.
- Portability is a secondary concern to optical performance.
When to Choose the 20-60×80 Spotting Scope
This scope is a fantastic all-rounder and is often the more versatile choice. It’s better for you if:
- You value a wider field of view for scanning landscapes and tracking moving animals.
- You need a good balance of performance and portability for hiking.
- Most of your use happens in decent daylight conditions.
- You prefer a scope that’s easier to hold steady at higher magnifications.
Practical Considerations Before You Buy
Beyond the specs, a few real-world factors will affect your satisfaction. Don’t overlook these steps.
- Try Them With Your Tripod: A flimsy tripod will ruin the experience of any high-magnification scope. Ensure your current tripod can stablely support the scope’s weight, especially the heavier 85mm model.
- Check Eye Relief: If you wear glasses, look for scopes with long eye relief (16mm or more). This allows you to see the full field of view without removing your glasses.
- Consider Lens Quality: The glass quality and coatings are as important as the lens size. Fully multi-coated lenses will provide a sharper, brighter image than a larger lens with poor coatings.
Making Your Final Decision
So, which one should you get? Here’s a simple flow to follow.
- Priority Check: Is maximum light gathering and power your #1 need? Lean toward the 25-75×85.
- Usage Check: Do you move around a lot and need to find subjects fast? Lean toward the 20-60×80.
- Budget Check: Often, the 85mm scopes are more expensive. Decide if the performance gain is worth the extra cost and weight for your specific uses.
Remember, the “better” scope is the one that you’ll actually take with you and use effectively. For many people, the versatility and manageability of the 20-60×80 makes it the winning choice. But for specialized, long-range applications, the 25-75×85’s advantages are real.
Frequently Asked Questions (FAQ)
Is 80mm or 85mm spotting scope better?
The 85mm scope is technically better at gathering light, which helps in low light. The 80mm scope is usually smaller and lighter. The best choice depends on whether you prioritize peak performance or portability.
What is a 20-60×80 spotting scope good for?
A 20-60×80 spotting scope is an excellent all-purpose tool. It’s great for birdwatching, wildlife observation, hiking, and some target shooting. Its wide 20x view makes it easy to find what your looking for.
Is 75x magnification good for a spotting scope?
75x magnification is very powerful and allows for extreme long-distance viewing. However, at that high power, image shake and atmospheric distortion become significant issues. It requires a very sturdy tripod and is best used in stable air conditions.
Can you see planets with a 25-75×85 spotting scope?
Yes, you can see planets like Jupiter and Saturn as bright discs, and you might even glimpse Jupiter’s moons. However, a spotting scope is not a replacement for a telescope designed for astronomy, but it can provide some enjoyable casual views.
