Aimpoint manufactures a red dot sight without magnification or optical
distortion. It uses a LED (light emitted diode) which is totally
harmless for the eyes.
What a red dot sight is not:
It is not a magnifying scope with an illuminated reticle. With
illuminated reticle, the dot must be centered in the sight and you have
an eye relief to think of. With a red dot sight from Aimpoint, you don't
have to center the dot and you have no eye relief.
It is not a laser. A laser is visible on the target. The red dot sight
is only seen by the shooter.
It is not an holosight. The holosight technology is less performant in
terms of battery life time for example and is dangerous to the eyes if
the lens brakes.
In fast shooting situations an Aimpoint red dot sight is absolutely
superior to all other types of sight and is user's friendly.
An electronic sight requires power to work. The length of time that the
red dot can remain lit depends on two things; the power consumption of
the light source and the capacity of the battery.
Aimpoint’s choice of batteries is based on availability as well as
storage and temperature characteristics. To achieve the longest possible
operating times, Aimpoint has therefore focused its efforts on
developing a completely new technology called Advanced Circuit
Efficiency Technology (ACET), which has extremely low power consumption
compared to other light sources.
The batteries used are 3V Lithium, chosen because of their superior
temperature and storage capabilities.
ACET sights can last nearly
(on setting 7 out of 10) on a single DL1/3N battery. That is 49,000
hours more than other competitive sights on the same setting.
The size of the dot
You can buy ACET sights in two different dot sizes, 2 or 4 MOA*. When
factoring in speed and accuracy, extensive trials have shown that 4 MOA
is the optimal dot size for most users. Tests performed by the military
have repeatedly proven that one single red dot is the reticle with which
marksmen most quickly fire a well-aimed shot.
*MOA (Minute of angle)
1 MOA = 30 mm at 100 m (1” at 100 yards)
2 MOA = 60 mm at 100 meters (2" at 100
4 MOA = 120 mm at 100 meters (4" at 100
In practice this means that the 4 MOA dot covers the target with:
30 mm at 25 meters (1" at 25 yards)
60 mm at 50 meters (2" at 50 yards)
120 mm at 100 meters (4" at 100 yards)
