Red Dot V.S. Holographic Sights
When it comes to sighting mechanisms for weapons, red dot and holographic sights are the popular choices.The differences between the two are not readily identifiable by just a simple side by side inspection and comparison. With a red dot, or reflex sight, you have a low power LED that produces the reticle, while a holographic sight uses a more powerful laser that bounces around to produce the holographic image of the reticle.
1. The big difference isRed dot sights use a LED to produce the reticle, while a holographic sight bounces a LASER to produce a holographic reticle. Besides, the reticuleof holographic sightshas a variety of forms and can be arbitrarily edited with a large field of view.
2. Holographic sights consume more power compared to red dot sights.So the biggest impact of this difference is the duration of the battery life for the sights.
3. Holographic sights are more immune to parallax errors compared to red dot sights,that is the biggest advantage of holography sights.Parallax problems with red dot sights appear when the eye is not perfectly aligned with the sight, as in this case, the line that is drawn from the eye to the reticle and beyond is no longer parallel with the barrel. This problem is more pronounced as you increase the distance between the shooter and the target. The holographic reticle in a holographic sight is able to composite for this misalignment, thereby reducing errors due to parallax distortion, even at very long distances.
4. Holographic sights have a lower temperature tolerance compared to red dot sights.Holographic sights are not as immune to temperature variations as red dot sights. So if you are going to a location which is too hot or too cold, then it may be better to carry a red dot sight instead of a holographic sight.
5. The holographic has no mirror reflection, it has better concealment than the red dot.
6. The field of view of the holographic sights is bigger than the red dot’s.
