There is a big difference between a red dot sight and laser sight. The function of a laser sight is to emit a beam of light onto the target but a red dot will reflect an image onto the glass of the sight and then superimpose a dot onto the target. With the red dot sight, the target is sighted although it is not magnified in the lens. A telescope can be used with this sight to magnify the target. Handguns, sub machine guns, and shotguns used at close range can use a red dot sight since they do not need magnification. A red dot sight offers a good level of precision and accuracy.
The following discussed how the red dot sight works. The sight has a lens that is concave and it has a very thin metallic coating which is able to reflect only red light. The light emitting diode inside the sight tube reflects a red dot in the lens. So when you look through the sight, what you see is a red dot which looks as though it has been projected onto the target. The sight does not have pinpoint accuracy, but it offers some level of assurance that you will hit your target by using the proper aiming and firing techniques. You can adjust the sight up and down as needed.
Red dot sights come in different types. If you compare a full tube red dot sight, you can mistake it for a telescopic sight. If you own a shotgun, then this is the sight ideal for your use. You can get other accessories for your red dot sight including haze reducing filters, sun shades, and flip up lens covers. Another type is the open sight or the mini red dot sight since they are smaller and weigh less than the full tube sight. There are no accessories like sun shades of haze filters that can be used with the open or mini red dot sight. Smaller than the full tube sight, the small tub sight can also use haze filters and sun shades.
One of the things that you need to do when buying a red dot sight is to look through the sight to determine the comfort you get with the way the sight works. If you are trying to improve the accuracy of your aim but you are color blind, then the red dot sight will not work for you. Since there are different types of red dot sights, you should know the type that you need and this depends much on your shooting needs. If you purchase a red dot sight, you can be sure that it will help improve the level of your accuracy.
