Red Dot Sight vs Holographic Sight

We are often asked what is the difference between Red Dot Sight vs Holographic Sight. Holographic sights and red dot sights are two popular types of scopes used as sighting mechanisms on various weapons. These two have some major differences which are not discernible by comparison or a simple inspection conducted by putting one beside another. When used for some time, the differences become more and more noticeable to shooters. Read our Red Dot Sight vs Holographic Sight points below to find out the differences between the two sights.

Red Dot Sight vs Holographic Sight

Use of laser

A red dot sight, also known as a reflex sight, has an LED of a low power which produces the reticle. A holographic sight, on the other hand, makes use of a more powerful laser beam which bounces about and produces a holographic picture of the reticle.

Battery consumption

The use of a more powerful laser has a major impact on the lifespan of the battery life of the scope. As holographic sights hog more power, the battery dies faster as compared to when a red dot sight is used. In order to avoiding the battery losing its power, it is always advised that you turn the sight off in case you do not wish it operate it for some time. Quicker consumption of battery is a major issue with holographic sights and you need to keep in mind to turn the scope off while it is idle.

Parallax distortion

Holographic sights are resistant to parallax distortion. Parallax problems occur in red dot sights when your eye is not aligned properly with the sight. In such cases, the line drawn from the eye to the reticle and even beyond is not parallel any more with the barrel. The problem is even more prominent once the distance between the target and the shooter is increased. In holographic sights, the holographic reticle can compensate this type of misalignment and this helps in minimizing errors resulting from parallax distortion – even at extremely large distances.


When you use both types of sights, one after the other, you can also realize the holographic sights are a little heavier than red dot sights. Also, the former are slightly more complex to handle and use than red dot sights. In case you do not have some heavy usage with your scope and do not demand a too high performance from your scope, it can be better and easier for you to take along a red dot scope.

Temperature tolerance

When compared to red dot sights, holographic sights are found to come with a lower temperature tolerance. Unlike red dot sights, they are not as resistant to temperature variations. It is recommended that you carry a red dot sight rather than make use of a holographic sight in case you are moving to an area that is very cold or very hot.

The holographic weapon sight is considered to be superior to red dot scopes, both electronically and optically. The two types of scopes vary in construction and optical performance. Red dot scopes make use of a technology that is older by 3 decades and naturally the improvement is quite less. But red dot scopes are also superior in some areas, such as weight and temperature tolerance.
