Telescopic Sight (Scope): Small telescope mounted on your firearm. A scope gathers light to brighten the image, uses mirrors and lenses to magnify the target, and does away with aligning rear and front sights. The aiming device inside the scope is called the “reticle.” To aim, you simply look through the scope, and line up the crosshairs, post, or dot with your target. Telescopic sights provide the most accurate aiming, which makes them popular for hunting.
Dot Sight: Small device mounted on your firearm. A dot sight uses electronics or optical fibers to project a glowing dot or other mark on a lens in front of the shooter’s eye. Some dot sights also magnify like telescopic sights.
A telescopic sight, also known as a scope, is used for the purpose of magnifying the target. When using a scope, hunters or shooters can see their targets more clearly and in greater detail. This is achieved through the magnification capabilities of the scope, which enlarge the image of the target.
Telescopic sights, often called “scopes,” are small telescopes mounted on top of the firearm. These magnify the target so accurate shots can be taken at longer ranges. Some telescopic scopes have a variable power feature that allows the magnification to be changed.
Typical standard parallax-free distances for hunting telescopic sights are 100 yards (91 m) or 100 meters (109 yd) as most sport hunting rarely exceed 300 yd/m.
The basics of it are this; if your scope has a 1st focal plane, when you increase the magnification, the reticule will also increase in size along with the image. If you have a 2nd focal plane, the reticule will remain the same size and only the sight picture will get bigger.
Scopes offer magnification for long-range precision and are ideal for rifles. Sights are generally used for quick target acquisition at closer range, which is more suitable for shotguns or short-range rifle scenarios.
Key Differences Between Rifle Scope and Red Dot Technologies
Red dots have no magnification, providing an aim point overlay. Precision vs Speed - At high zoom, scopes excel for pinpoint accuracy at long range. Red dots lack magnification but acquire close targets lightning fast.
Because there is no magnification the shooter need not worry about parallax or eye relief. The long eye relief makes red dot sights appropriate for firearms with heavy recoil that might drive a conventional short eye relief telescopic sight into the shooter's eye.
Some competition disciplines stipulate the use of fixed magnification scopes only, but for most other shooting situations the flexibility of variable magnification is best. Most common are scopes with 3-12x, 4-16x and 6-24x magnification ranges, which cover most airgun scenarios.
Holographic optics are very durable and can withstand a beating. It is the optic of choice for soldiers from the Navy SEALS, the Green Berets, and the Marine Raiders.
Most shooters find they can shoot more accurately with a red dot than with iron sights, particularly at distance and when speed is an issue. With the dot, you can easily “holdover” for longer shots, while still seeing the entire target in the window.
Never mix ammunition, such as carrying a caliber or gauge your companion uses. A common mistake involves putting a 20-gauge shotshell into a 12-gauge shotgun. The smaller gauge shell will slide through the 12-gauge chamber and partly down the barrel, causing an obstruction.
The advantages of telescopic sights are several. Obviously, they magnify the target and make it easier to see. In many cases this magnification enables accurate shots over much greater distances than would be possible with metal open sights.
Depending on the type of cartridge, what type of game you are hunting and the terrain, you may be satisfied with the rifle zeroed at 100 yards. Many times hunters will sight their rifle in an inch or two high at 100 yards so that it will be centered at 200 yards.
What Is Scope Magnification? Scope magnification indicates how many times the view through a scope has been increased and is displayed as a number followed by an "x". A 3x magnification example would mean that the view through the scope is three times that of the actual object or target.
When you place the crosshair on the target, the impact of the bullet should fall where you place the crosshair. This is known as the sight in or zeroing process.
The diopter is in principle a vertically and horizontally (elevation and windage) adjustable occluder with a small hole (aperture), and is placed close in front of the shooter's aiming eye. Through this small hole the shooter can view the front sight component(s) and the intended target.
