Romeo 8t Vs Eotech: In-Depth Comparison 

romeo 8t

Now let’s see the details of how the two red dots compare.

Projection Type:

The Sig ROMEO 8T is a reticle projection, like Aimpoint. The image is projected onto the front lens. The EOTech is a true laser holograph consisting of many dots of laser light, diffused, forming the reticle on the lens. 

The Sig ROMEO 8T uses a type of projection technology called “reflex” or “direct view” projection to create the reticle. This technology involves an LED emitter projecting a dot or circle of light onto a partially reflective lens. The light is then reflected back to the shooter’s eye, creating the reticle image that appears to be floating on the target.

In contrast, EOTech sights use a different type of projection technology called a “true laser holograph.” This technology involves a laser creating a holographic image. It is displayed on a holographic film located between the lens and the target. The holographic film diffracts the laser light, creating a reticle image that appears to be floating in space.

So, both the ROMEO 8T and EOTech sights are red dot sights. However they use different types of projection technology to create the reticle. The difference in technology results in different reticle designs.

Verdict: This round is a draw because both types of reticles are good and the choice depends on personal preference. 

Glass Quality:

The Romeo 8T and EOTech have high-quality lenses with multi-coatings for clarity, light transmission, and contrast. Both lenses are treated with coatings that repel water, oil, and debris, but EOTech lenses also have anti-reflective coatings. The Sig ROMEO 8T has very clear glass and is comparable in clarity to the EOTech.

The glass quality can have a significant impact on the shooter’s ability to acquire and maintain a sight picture. Both Romeo 8T and EOTech have high-quality glass. 

The Romeo 8T uses a high-quality, fully multi-coated lens system. It provides excellent clarity, light transmission, and contrast. The lens is also treated with a proprietary coating that repels water, oil, and debris. This makes it easy to clean and maintain. 

EOTech also uses high-quality glass for their lenses, with anti-reflective coatings to reduce glare and improve light transmission. The lenses are also fog-resistant and sealed with O-rings to prevent moisture and debris from entering the sight. Some EOTech models also feature a protective hood around the lens to further protect against damage.

According to a user on, the glass on the Sig ROMEO 8T is very clear. And it is just as clear as the EOTech1. 

Verdict: This round is also a draw because both have excellent glass with reports of them being very similar. 

Image Quality:

The Romeo 8T has a bright and clear red dot reticle that is adjustable for brightness with ten settings. It also has a MOTAC system. User reviews suggest that the reticle is clear and works well under night vision. EOTech sights use a holographic image reticle, but some users report a fuzzy image quality issue.

The Romeo 8T uses a red dot reticle that lights up like a 4K neon sign. It makes it very bright and clear, even in low-light conditions. 

The reticle is adjustable for brightness, with ten brightness settings, and features a Motion Activated Illumination (MOTAC) system. This system powers up the sight when motion is detected and powers it down when it’s not in use. This even extends battery life. 

According to many user reviews, the reticle on the Sig ROMEO 8T is also very clear and works well under night vision. Note that night vision can help you see lasers

EOTech sights also use a reticle that appears as a holographic image on the lens. However, some users have reported that EOTech sights may be fuzzy. As a result, this can negatively impact image quality.

Verdict: Romeo 8T wins with high quality images with no complaints. 

Reticle Options:

When it comes to reticle options, the Sig ROMEO 8T and EOTech sights offer different choices. Romeo 8T has more options available. 

The Sig ROMEO 8T has four different reticle options. This is a great feature for shooters who prefer different styles of reticles. The reticles can be easily switched, allowing for customization to fit your personal setup.

EOTech sights

The options in Romeo are

  • Dot, Circle-Dot
  • Dot with Holds
  • Circle-Dot with Holds. 

This allows users to choose which one is for their personal setup and can also be switched. As mentioned previously, the Romeo 8T uses reticle projection technology. This means the image is projected onto the front lens of the sight.

In contrast, EOTech sights typically come with a single reticle design. However, some models offer the option to switch between different reticle patterns. As mentioned previously, EOTech sights use true laser hologram technology that creates the reticle by diffusing many dots of laser light onto the lens.

Verdict: Romeo 8T wins because of the more reticle options. 


When it comes to dimensions, the Sig ROMEO 8T and EOTech sights differ slightly in size. The 8T is slightly bigger in size than EOTech.

This makes it a relatively compact and lightweight sight that won’t add too much bulk to your rifle. The Romeo 8T also features a streamlined design that helps reduce snag points and improve maneuverability.

On the other hand, the EOTech EXPS3 measures 3.7 inches in length, 2.2 inches in width, and 2.9 inches in height. This makes it slightly smaller than the Romeo 8T in overall size. 

However, it’s worth noting that the EOTech EXPS3 features a slightly bulkier design. and it may not be as streamlined as the Romeo 8T.

Verdict: This round is also a draw. That is because Romeo 8T might be bigger in size but it has a more streamlined design compared to EOTech.


When it comes to weight, there is a slight difference between the Sig ROMEO 8T and EOTech sights. The 8T is slightly heavier than other sights in the market. And EOTech is slightly lighter. 

The Sig ROMEO 8T weighs 13.7 ounces. This makes it slightly heavier than some other similar sights on the market. However, this extra weight can be beneficial in some ways. Because it can help absorb recoil and provide a more stable shooting platform.

On the other hand, the EOTech EXPS3 weighs in at 11.2 ounces. This makes it slightly lighter than the Romeo 8T. This can be an advantage for shooters who prioritize maneuverability and ease of use over stability and recoil management.

Verdict: EOTech wins this round for being lighter. 


Both the Sig ROMEO 8T and EOTech EXPS3 are designed to withstand tough environmental conditions. This includes exposure to water and moisture.

The Sig ROMEO 8T is rated IPX-8, which means it’s completely waterproof. And it can be submerged in water without suffering any damage. 

In addition to its waterproof design, the Romeo 8T is also fog-proof. This helps ensure a clear sight picture in any weather conditions.

The EOTech EXPS3 is similarly designed to withstand exposure to water and moisture. In fact, it’s rated as submersible up to 10 meters. This makes it a great choice for use in wet and humid environments. 

Like the Romeo 8T, the EOTech EXPS3 is also designed to be fog-proof. This helps ensure clear sight pictures in any weather conditions.

Verdict: This round is a draw because both have similar subversive capabilities. 


Mounting is an important consideration when selecting a red dot sight. Because it can impact how quickly and easily you’re able to install and remove the sight from your firearm.
