If you’re wondering how do you buy binoculars, you’re not alone. It can feel overwhelming with so many options, but this guide will make it simple. We’ll walk you through the key features and choices so you can find the perfect pair for your needs.
How Do You Buy Binoculars
The first step isn’t looking at models. It’s looking at yourself. Ask what you’ll primarily use them for. Your main activity determines almost everything about the right pair.
Identify Your Primary Use
Different activities need different binoculars. Here are the most common uses:
- Birdwatching: You need a bright, clear image and a wide field of view to track moving birds. 8×42 is a classic choice.
- Hunting: Durability and performance in low light (dawn/dusk) are key. Look for rugged, waterproof models.
- Stargazing/Astronomy: You’ll want larger objective lenses (like 50mm or more) to gather maximum light. A tripod adapter is helpful.
- Sports & Concerts: Compact or mid-size binoculars are best for easy carrying. A wider field of view helps you follow the action.
- General Travel & Hiking: Lightweight and compact size is crucial. Look for a good balance of power and portability.
Understand the Numbers: Magnification & Objective Lens
Every binocular has two numbers, like 8×42 or 10×50. This is the most important spec.
- First Number (Magnification): An “8x” means the object appears 8 times closer than with the naked eye. Higher isn’t always better. More magnification makes the image shakier and the field of view narrower. 8x or 10x is ideal for most handheld use.
- Second Number (Objective Lens Diameter): This is the size of the front lenses in millimeters. Larger lenses (like 42mm vs. 25mm) gather more light, giving a brighter image, but they also make the binoculars bigger and heavier.
Key Features to Compare
Once you know your use and the basic numbers, look at these features.
Prism Type: Roof vs. Porro
This affects the shape and often the price. Roof prism binoculars have straight barrels; they are sleeker, more compact, and generally more expensive for high-quality optics. Porro prism binoculars have offset barrels; they are often bulkier but can offer excellent value and a good 3D image.
Lens Coatings
Coatings reduce glare and increase light transmission. Look for terms like “fully multi-coated.” This is a sign of better optical quality and a brighter, clearer view. Binoculars labeled just “coated” are usually the most basic.
Focusing System
Most binoculars have a central focusing wheel. Also check for a diopter adjustment (usually on the right eyepiece). This compensates for the difference in strength between your two eyes, which is essential for a sharp image.
Eye Relief
This is the distance your eye can be from the eyepiece and still see the full image. It’s critical if you wear glasses. Look for eye relief of 15mm or more. Long eye relief models often have twist-up eyecups that you can adjust down if you wear glasses, or up if you don’t.
Weight & Ergonomics
If you’ll hold them for long periods, weight matters. Pick them up. Do they feel comfortable in your hands? Are the focus wheel and eyecups easy to adjust? A good fit reduces hand strain.
Durability: Waterproof & Fogproof
For any outdoor use, choose binoculars that are nitrogen-purged and O-ring sealed. This means they are waterproof and, more importantly, fogproof. Internal fogging from temperature changes can ruin a view and the optics over time.
Your Step-by-Step Buying Process
- Set Your Budget: Good binoculars start around $100. $200-$500 gets you excellent quality for most hobbies. Serious optics can cost more.
- Research Online: Read reviews and narrow down 2-3 models that fit your use case and budget. Pay attention to consistent praises or complaints.
- Try Before You Buy (If Possible): Go to a store. Look through different models. Compare the view across the street, not just across the room. Check for a sharp, clear image edge-to-edge.
- Test the Focus: Quickly focus on objects at different distances. Is the focus wheel smooth and precise?
- Check the Feel: Hold them for a minute. Are they too heavy? Do they balance well in your hands?
- Final Check: Ensure they come with a good warranty and consider if you need accessories like a strap, case, or lens caps.
Common Mistakes to Avoid
- Buying the highest magnification (like 20x or more) for handheld use. The image will be very shaky.
- Ignoring eye relief if you wear glasses. You won’t see the full field of view.
- Choosing huge 50mm binoculars for long hikes when a 32mm model would be much more comfortable.
- Assuming all waterproof ratings are the same. Look for specific mentions of O-ring sealing.
- Overlooking the diopter adjustment and not setting it properly for your eyes.
FAQ Section
What is the best all-around binocular size?
For most people, an 8×42 binocular is the best all-around choice. It offers a good balance of magnification, a bright image, a wide field of view, and a manageable size for carrying.
How much should I spend on a decent pair of binoculars?
You can find usable binoculars under $50, but for good optical quality and durable construction for outdoor use, plan to spend between $150 and $400. This range offers significant improvements in clarity, brightness, and build.
Are compact binoculars worth it?
Yes, if portability is your top priority (like for travel or backpacking). Just know that their smaller lenses (e.g., 25mm) won’t gather as much light as full-size models, so image brightness may be lower in dim conditions.
What does “field of view” mean?
Field of view is the width of the area you can see through the binoculars at a specific distance, usually measured in feet at 1000 yards. A wider field of view makes it easier to locate and follow moving objects, like birds or athletes.
How do I clean binocular lenses properly?
First, use a soft brush or blower to remove dust. Then, use lens cleaning fluid and a microfiber cloth designed for optics. Gently wipe in a circular motion from the center outward. Never use household cleaners or rough materials like your shirt, which can scratch the coatings.
Remember, the best binoculars for you are the ones that fit your specific needs and feel comfortable to use. By following these steps, you’ll be able to make a confident choice and enjoy a clearer view of the world around you. Take your time, and don’t hesitate to test a few models side-by-side to see the difference for yourself.
