EOTech Holographic Sights

EOTech holographic sights

EOTech is one of the world's best-known manufacturers of holographic sights. Its HWS — Holographic Weapon Sights — use holographic technology to display the reticle through a wide optical window, supporting fast target acquisition while maintaining a broad view of the surrounding environment.

At Carbin, you can compare different EOTech holographic sights from the XPS, EXPS and 5 Series families, together with compatible magnifiers that extend the capabilities of the system.

Choosing an EOTech is not simply a matter of selecting a model. You should also consider the firearm, reticle, night vision compatibility, battery type, mounting system, control layout and whether a magnifier will be used.

What is an EOTech holographic sight?

A holographic sight uses a different optical system from a conventional LED red dot sight.

In an EOTech HWS, holographic technology generates the reticle image that the shooter sees through the sight window.

The system provides a fast aiming reference without optical magnification while allowing the shooter to remain focused on the target and surrounding scene.

EOTech HWS models are 1× non-magnified optics. When magnification is required, they can be paired with a separate magnifier.

EOTech vs red dot sight: what is the difference?

An EOTech holographic sight and a red dot sight can serve a similar purpose, but they do not generate the aiming reference using the same technology.

A conventional red dot sight normally uses an LED emitter and a reflective lens. An EOTech HWS uses holographic technology to create the reticle.

How does an EOTech reticle work?

One of EOTech's most recognisable features is the combination of a large outer ring and a fine central aiming point, with several reticle configurations available depending on the model.

The outer ring provides a fast visual reference, while the smaller central dot gives the shooter a finer aiming point.

On several EOTech configurations, the central dot measures 1 MOA. As a practical angular reference, 1 MOA corresponds to approximately 2.9 cm at 100 metres.

The exact reticle varies by model, so it is important to check the reticle configuration before choosing a particular EOTech.

Why is the EOTech viewing window different?

The rectangular window used by EOTech HWS models is designed to create a very open visual experience.

When used with both eyes open, the shooter remains focused on the target while the reticle serves as the aiming reference.

This design supports:

• fast target acquisition;
• tracking moving targets;
• broad peripheral awareness;
• rapid transitions;
• intuitive reticle acquisition.

EOTech XPS or EXPS: what are the differences?

The EOTech XPS and EXPS families share a compact HWS architecture but differ in areas such as mounting configuration, control placement and available versions.

These differences can become particularly important when the sight is combined with other optical components, because button placement and mounting height can affect the ergonomics of the complete setup.

The choice between XPS and EXPS should therefore be based on mounting system, control layout, height, night vision requirements where applicable and the complete firearm configuration.

EOTech XPS2 vs XPS3

One of the important distinctions between certain XPS variants is night vision compatibility.

If night vision equipment will not be used, that feature may not be necessary. If it is required, the exact model version should be checked before purchase.

EOTech EXPS2 vs EXPS3

The same principle applies to the EXPS family.

Models such as the EOTech EXPS3 include settings designed for use with compatible night vision devices, while other variants are intended for conventional use.

The right choice therefore depends on the features actually required rather than simply choosing the model with the higher number.

EOTech 512 and 552

The EOTech 512 and 552 represent the brand's more traditional, longer HWS format.

They occupy more rail space than the XPS and EXPS families and use a different battery configuration.

The best option depends on available rail space, preferred power source and whether features such as night vision compatibility are required.

EOTech magnifiers: G33, G43 and G45

It is important to distinguish EOTech holographic sights from the brand's magnifiers.

An EOTech magnifier does not generate a holographic reticle and does not replace the HWS. It is a separate magnified optic positioned behind a compatible sight.

The EOTech range includes models such as the G33, G43 and G45, with different magnification levels, dimensions and configurations.

This allows the holographic sight to remain the primary 1× optic while magnification can be introduced when required.

The EOTech G33 should therefore be understood as a magnifier within a modular optical system, not as a holographic sight itself.

Which EOTech should you choose?

Before choosing an EOTech, consider the following:

1. Define the firearm and mounting platform.
2. Decide whether night vision compatibility is required.
3. Check the reticle used by the model.
4. Compare XPS, EXPS and 5 Series formats.
5. Consider control placement.
6. Compare battery type and operating time.
7. Decide whether a magnifier will be used.
8. Check weight, mounting height and available rail space.

EOTech on rifles and long guns

EOTech HWS models are strongly associated with long-gun configurations.

The sight should be considered together with mounting position, rail space and firearm ergonomics.

If a magnifier may be added later, sufficient space should be reserved for the complete optical system.

Can you use an EOTech with both eyes open?

Yes. This is one of the key principles behind using a 1× holographic sight effectively.

The shooter remains focused on the target while the reticle provides the aiming reference, allowing both eyes to continue gathering information about the surrounding environment.

EOTech and night vision

Not every EOTech offers the same level of night vision compatibility.

Some versions include dedicated brightness settings for use with compatible night vision equipment, while others are designed for conventional use only.

Night vision compatibility should therefore always be checked on the exact model.

EOTech vs Aimpoint

EOTech and Aimpoint are two of the best-known names in premium 1× optics, but they use different technical approaches.

EOTech is best known for its Holographic Weapon Sights, while Aimpoint is one of the major reference brands in LED red dot sights.

EOTech is distinguished by its holographic technology, viewing window and reticle configurations. Aimpoint is particularly well known for the long battery life of many models and its wide range of optic formats and mounting systems.

Is EOTech the only manufacturer of holographic sights?

EOTech's reputation should not be confused with the claim that no other manufacturer can produce holographic optics.

The brand has, however, played a major role in bringing holographic technology into compact aiming systems and has made the HWS concept one of the most recognisable architectures in the category.

It is also important to distinguish true holographic systems from products sometimes described commercially as “holographic” even though they technically use an LED reflex architecture.

The history of EOTech

EOTech's history is closely connected with the development of holographic and optical technologies in Michigan.

In 1972, the Environmental Research Institute of Michigan — ERIM — was established, and research from that environment later contributed to developments involving holography.

In 1995, EOTech was created to commercialise this technology in compact aiming systems, and in 1996 the first Holographic Weapon Sight was introduced.

In 2005, EOTech was acquired by L-3 Communications. Since 2020, the company has operated again as an independent business.

Today, the range extends beyond HWS models and includes magnifiers, Vudu riflescopes and other electro-optical products.
