Sig Romeo 7 vs Aimpoint Pro – How do they Compare?

Motion Sensors 

One of the main factors that you must consider with your red dot is the operation of the sensors especially when you are out in the field. The Aimpoint Pro sight works well in maintaining a continuous presence as soon as it has been activated. This means that the red dot is always activated. If you find the constant light distracting, you can easily adjust the sight to a lower level and the night vision setting will be activated. Romeo 7 is designed with a Motion Activated Illumination (MOTAC). This function turns on the brightness as soon as the optic senses any kind of movement. When there is no type of movement the optic goes off. The MOTAC function allows the sight to maintain power which is great especially because Romeo 7 operates on AA batteries. The MOTAC feature makes the Romeo 7 a favorite when compared to the Aimpoint Pro optic.


Romeo 7 as well as Aimpoint Pro are booth designed with a 2 MOA reticle. Aimpoint Pro is designed with 10 different light settings; six for daylight use and four for night vision use. Romeo 7 is designed with 11 different settings, nine for daylight use, and two for night vision. When working in normal daylight lighting conditions, shooters should make use of the sixth setting. When it comes to Romeo 7 the most preferred setting during the day is number 7. Providing shooter with a wider variety of lighting settings makes the Romeo 7 a better choice than the Aimpoint Pro.

Position and Balance 

This is yet another issue that many shooters must take into consideration when it comes to their red dots. This factor is greatly affected by the positioning and weight of the sight. Romeo 7 weighs 12.6 oz making it heavier than the Aimpoint Pro that only weighs 7.8 oz. When attaching the Aimpoint Pro to your pistol, you will hardly feel the difference unlike the Romeo 7 that might take some getting used to because it is much heavier. When it comes to the positioning, the buttons of the Romeo 7 are designed to face the user. This design improves your positioning and your aiming giving you a chance to maintain sight of your target as you maneuver from one mode to the next. The positioning of the controls on Romeo 7 enhances any shooter’s performance and this makes it a better choice than Aimpoint Pro.
