You can get up to 1250 hours run time (33% lighter than alkaline batteries) with the AA models eotech 552 and 512 with the AA lithium batteries. These batteries sell at department stores for $12-$18 a pair. order at the bottom of this page.
Eotech Has introduced a brighter and sharper reticle to all Eotech holographic weapon sites Also, these changes included an extension of 2 times the battery life at the brighter levels, yielding a total of 200 hrs continuous runtime in the 511 and 551 and 630 hrs continuous in the 512 and 552. If lithium AA batteries there was also the elimination of the one-second delay in the scrolling feature when changing the sight's brightness. These changes are all collectively known as Revision Level F. This has been noted on the outside of the protective hood with the capital letter "F". All models produced since the beginning of Feb of this year is this new Rev level. The previous Rev E level is no longer produced. This revision level applies to all models.
Today's F-14 Tomcats use holographic heads-up technology to meet the requirement for super fast, accurate target acquisition. It has been proven by TopGun fighter pilots throughout the world.
The HOLOgraphic Weapon Sight (HWS) is the 1st electro-optic sighting system to apply holographic technology to small and medium-sized weapon platforms. When used in Close Quarters Battle (CQB) environments, this revolutionary weapon optic delivers amazing speed and accuracy gains, uncompromising use of peripheral vision, leaveas no muzzle-side optical signature and is packaged in a compact, durable unit.
Now deployed with elite Special Forces and SWAT teams the world over, the HWS delivers vastly improved shooting performance for all levels of operators.
The HWS uses state-of-the-art digital electronics design. Twenty brightness levels ensure proper brightness control in either low light or very bright sunlight. An on-board microprocessor provides automatic battery check indicator, up/down brightness scrolling and programmable auto shutdown features. All electronics are fully encapsulated in shock absorbing resin compound.
The HOLOgraphic Advantage
The holographic patterns have been designed to be instantly visible in any light, instinctive to center regardless of shooting angle, and to remain in view while sweeping the engagement zone. Reticles are designed as large, see-through patterns to achieve lightning quick reticle to target acquisition without covering or obscuring the point of aim.
Heads Up, Full View
The HWS employs a true Heads-Up Display that eliminates blind spots, constricted vision, or the tunnel vision associated with tubed sights. All user controls are flush to the HWS's streamline housing with no protruding knobs, battery compartments or mounting rings blocking vision at the target area. True, 2 eyes open shooting is realized. Instant threat identification is achieved by maximizing the operator's peripheral vision and ultimately gaining greater control of the engagement zone.
The Magic of Holography
In holography, all the information required to reconstruct the reticle image is recorded everywhere in the Heads-Up display window. If the window is obstructed by mud, snow, rain, etc., the HWS remains fully operational , with point of aim/impact being maintained. Even in such extreme cases where the laminated window is shattered, the HWS is fully functional! As long as the operator can see through any portion of the window, the entire reticle pattern is visible on target...the operator can still engage with confidence.
Extreme Durability
The HWS has been designed and tested to provide consistent, reliable performance even in the most hostile operational environments. It is waterproof, fogproof, shockproof, and temperature proof.
The HWS is designed to withstand Mil-Spec drop tests and still remain fully operational and hold zero. The HWS has been extensively tested in a punishing recoil simulator generating 3,500 G's of acceleration in less than 0.5 milliseconds (the recoil of a .454 Casull revolver) as well as various environmental chambers).
The Heads Up Display is constructed with a 3 layer, shatterproof laminate glass that is 3/16" thick for added durability. Additional protection of the Heads Up Display is provided with a "roll bar" ruggedized hood.
No Revealing Signature
The HWS does not emit any muzzle side position revealing light signature...the projected reticle pattern is visible only to the operator. Even Gen III night vision equipment cannot detect muzzle side signature of the operator's position.
All optical surfaces are flat and treated with anti-reflective coatings eliminating additional muzzle side signature due to reflective glare. No need for costly glare elimination filters that reduce the effective light transmission and further dim the target area.
