The BSA red dot sight test measures how well a person can use a BSA red dot sight on a gun. BSA red dot sights are good for quarter and medium range targets.
A red dot sight projects an illuminated red dot onto a lens to help aim your firearm, while a laser sight emits a laser beam towards the target for aiming. Red dot sights are more for precision shooting, while laser sights can provide quick target acquisition but are affected by environmental conditions.
Holographic sights tend to be used on weapons and are primarily used to look through glass. They are also more accurate than iron sights because a red dot will appear where you wish to hit.
The difference is that red-dot sights are cheaper to make, less accurate, and not as durable as holographic sights are. Both use an LED (light-emitting diode) to create a reticle (target dot) imposed onto a clear surface, but holographic sights are usually more accurate at long distances and do not "change" position in the glass when looked through at a different angle, which the reticles of red-dot sights often do. The key to this difference is that red-dot sights refract the laser emitted by the LED only once, allowing room for error, whereas holographic sights refract the one beam from the LED multiple times from multiple angles so that each laser refraction will reach the same place every time and will appear to remain consistent in its position to the shooter's eye.
It means the location of the red dot aligns with the iron sights. What this means is that a shooter doesn't have to change their sight picture when going from irons to optics, and they can use their irons viewing through the optic sight.
Red dot sights are generally very robust and have a long battery life. Some Aimpoint red dot sights have over 8 years' worth of continuous use from one singe battery. This makes the scope ideal for hunting, conventional warfare and home-defense as you don't know when you need to use the sight and have a great need of having it on all the time. Holographic sights are heavy and energy hungry but give a very good sight picture with better parallax. They are good in situations where you can predict when you will be using them. Examples are in competitive shooting or in advanced military and police operations where it is the user that starts the engagement. For the average gun owner the difference is negligible.

There are a number of optical devices used on firearms. The most common is a telescoping sight, usually referred to as a "scope". There are others however, that while optical, do not magnify the image. These are sometimes referred to as "red dot" sights, and they use a sighting method that seems to suspend a red dot in the air where the bullet impact will be. Another version of the same thing is referred to as a "holographic" sight.
Red dot over the fore head signifies the third eye (knowledge).Symbolic of mental vision.
A red dot sight uses an LED light reflected onto a coated lens to create the aiming point, while a holographic sight uses a laser transmission hologram to create the reticle. Holographic sights tend to offer a more versatile reticle design and better accuracy, but they are generally bulkier and more expensive than red dot sights.
