Spotting Scopes Buyer's Guide

When binoculars can't pull in enough detail — a hawk perched 300 yards out, a bullet hole on a paper target, or a shorebird you need to identify by plumage — a spotting scope bridges the gap. With 20–60x magnification and objectives up to 100mm, a quality spotting scope mounted on a tripod delivers resolution that handheld optics simply can't match.

This guide covers the specs that matter, how to choose between angled and straight bodies, what to look for in glass and coatings, and how to match a spotting scope to your activity and budget.

Spotting scope specs follow a similar format to binoculars — a number like 20-60x80 tells you the zoom range and objective lens size. Here's what each spec means and why it matters.

1. Magnification Range

Most spotting scopes use a variable-zoom eyepiece — typically 20-60x or 15-45x. The low end (20x) is for scanning wide areas and finding targets. The high end (60x) pulls in fine detail on distant subjects.

In practice, atmospheric conditions often limit usable magnification. Heat shimmer and air turbulence mean that above 40-45x, image quality degrades on warm days. Cold, calm mornings give the sharpest high-power views. Start at the low end, find your subject, then zoom in only as far as conditions allow.

2. Objective Lens Diameter

The front lens size determines how much light the scope gathers. Larger objectives mean brighter images, especially at dawn and dusk.

• 60-65mm: Compact and lightweight. Good for daytime use and hiking where every ounce counts. Limited in low light.
• 80-86mm: The most popular size. Excellent balance of brightness, detail, and portability. The go-to for birding, hunting, and range shooting.
• 100mm+: Maximum light gathering for serious dawn/dusk observation or digiscoping. Heavier — plan on a sturdy tripod.

3. Eye Relief

The distance between the eyepiece and your eye where you see the full field of view. If you wear glasses, look for 15mm or more of eye relief. Most quality eyepieces have twist-up eyecups with click-stops to adjust for glasses or bare eyes.

4. Field of View

How wide an area you see at a given magnification, measured in feet at 1,000 yards. At low power (20x), expect around 100-115 ft at 1,000 yards. At 60x, this narrows to roughly 40-50 ft. A wider FOV makes it easier to find birds and track moving subjects before zooming in.

5. Close Focus Distance

The minimum distance at which the scope can produce a sharp image. For birdwatching, 15-20 feet is ideal — it lets you observe close subjects without switching to binoculars. Most quality scopes close-focus to 15-25 feet.

6. Focus Mechanism

Two types are common:

• Dual focus — A coarse focus knob for quick adjustments plus a fine focus for precision. Preferred for target shooting and digiscoping where critical sharpness matters.
• Single focus — One smooth-action focus wheel. Simpler and faster for scanning and birding.

This is one of the first decisions you'll make, and it's largely a matter of how you use the scope.

Angled (45°) Body

The eyepiece angles upward at 45 degrees from the barrel. Advantages:

• More comfortable for extended seated or standing viewing — you look down into the eyepiece rather than craning your neck to a straight-back position.
• Easier to share between people of different heights without adjusting the tripod.
• Allows a shorter, lighter tripod since the eyepiece is already angled upward.
• Better for observing subjects above you (treetop birds, mountain ridges).

Angled bodies are the most popular choice for birdwatching and nature observation.

Straight Body

The eyepiece is in line with the barrel. Advantages:

• Faster to aim — you look straight through the scope toward the target, which is more intuitive.
• Easier to use from a vehicle, window, or ground-level position.
• Simpler to set up with a car window mount.

Straight bodies are often preferred for target shooting and hunting where quick target acquisition matters.

If you're unsure, angled is the more versatile choice for most field activities. Many of our scopes are available in both configurations.

At the higher magnifications a spotting scope delivers, glass quality and coatings matter even more than with binoculars. Small imperfections that are invisible at 8x become obvious at 40x.

ED (Extra-Low Dispersion) Glass

ED glass elements reduce chromatic aberration — the color fringing (purple or green halos) visible around high-contrast edges at high magnification. At 40-60x, chromatic aberration is very noticeable without ED correction. Look for ED glass in any scope you plan to use above 30x regularly.

Fully Multi-Coated Lenses

Multiple anti-reflective coatings on every air-to-glass surface maximize light transmission. With more glass elements than binoculars, spotting scopes benefit even more from quality coatings. Fully multi-coated (FMC) should be the minimum standard for any scope above the entry-level tier.

HD and UHD Designations

Manufacturers use HD and UHD to indicate premium glass formulations with higher light transmission and color accuracy. Athlon's G2 UHD line, for example, uses proprietary glass with measurably better resolution and contrast than their standard HD glass. These designations generally correspond to real optical improvements, though the specific gains vary by brand.

Phase Correction

Roof-prism spotting scopes benefit from phase correction coatings, just like roof-prism binoculars. These coatings maintain contrast and resolution by correcting light-path interference inside the prism. All quality spotting scopes include them.

The best spotting scope depends on what you're doing with it. Here's what to prioritize for each use case.

Birdwatching and Nature Observation

Birding is the single biggest use case for spotting scopes. You need good close focus (under 20 feet), a wide field of view at low magnification for finding birds in foliage, and enough optical quality to resolve plumage detail at 40x+. An angled body is strongly preferred for extended seated viewing at hides and blinds.

An 80mm scope with ED glass is the birder's sweet spot — bright enough for dawn/dusk observation, sharp enough for ID work, and not so heavy that you dread carrying it to the blind. Pair with a carbon fiber tripod to keep the total kit manageable.

Target Shooting and Range Use

Shooters need a scope that resolves bullet holes at 100-600+ yards. This demands good glass and enough magnification to read shot groups. A 20-60x80 or larger scope is standard. Straight or angled works — it depends on your bench setup. Dual focus (coarse + fine) is helpful for dialing in critical sharpness on paper targets.

Several of our scopes include ranging reticle eyepieces — the Athlon Ares G2 22x ranging eyepiece lets you estimate distance to targets using mil-dot markings.

Hunting

Hunters typically use a spotting scope from a fixed position — glassing ridgelines, scanning valleys, or evaluating game at distance before committing to a stalk. Priorities: low-light brightness (80mm+ objective), rugged waterproofing, and a setup that's quick to deploy. Weight matters if you're packing into backcountry; a 65mm scope shaves pounds versus an 85mm model.

Pair your scope with 10x42 binoculars for scanning and a rangefinder for precise distance to game.

Digiscoping (Photography Through Your Scope)

Spotting scopes double as telephoto lenses when paired with a smartphone adapter or DSLR camera adapter. The effective focal length of a 20-60x80 scope can reach 1,000-3,000mm equivalent — far beyond what most camera lenses offer. This makes digiscoping popular with birders and wildlife photographers who want extreme reach without carrying a massive telephoto lens.

For digiscoping, prioritize ED glass (chromatic aberration is magnified in photos), a smooth focus mechanism, and a sturdy tripod with a fluid head for panning. Several brands in our catalog offer compatible camera adapters.

Astronomy

A spotting scope can serve as a compact, portable telescope for casual stargazing. The Moon, planets, and bright star clusters are all visible through a quality 80mm scope. The advantage over a dedicated telescope is portability and dual-purpose use — bring it birding by day, stargazing by night. For serious astronomy, a dedicated telescope will offer better performance, but a spotting scope is a capable starting point.

A spotting scope without a tripod is nearly unusable. At 20-60x magnification, even tiny vibrations make the image a shaky blur. The tripod is as important as the scope itself.

Carbon Fiber vs. Aluminum

Carbon fiber tripods are lighter, absorb vibrations better, and don't conduct cold to your hands in winter. They cost more but are worth it if you carry your kit any distance. Aluminum tripods are heavier and more affordable — fine for stationary use at a range or blind where weight isn't a factor.

Head Type

A pan-tilt or fluid head lets you smoothly track moving subjects — essential for birding. A ball head is lighter and quicker to position but less smooth for panning. For target shooting, any stable head works since you're typically locked on a fixed position.

Height and Stability

Make sure the tripod reaches a comfortable viewing height for your position — seated, standing, or from a vehicle. With an angled scope body, you can use a shorter tripod than with a straight body. Stability matters more than maximum height; wider leg spreads and heavier builds resist wind vibration better.

We carry a range of tripods from Athlon and Bresser designed specifically for spotting scope use, in both carbon fiber and aluminum.
