- Stay Powered for 1,000 Hours on One Battery: A single CR123A battery keeps the optic running for 1,000 hours of continuous use on medium brightness. The Dynamic Wake feature turns the sight on when you move and automatically shuts off to save power when not in use.

DOT EHS-1 L Holographic Sight Accessories
- DOT EHS-1 ARD: This anti-reflection device (killflash) stops sunlight from bouncing off the front lens of your sight. It helps hide your position by eliminating objective lens glare during operations, while adding an extra layer of protection to the glass against scratches and dirt in the field.
- Dot ACRO Mount Diving Board: This forward mount frees up critical space on your handguard. It provides a secure, zero-holding platform to mount your IR lasers directly in front of the optic.
- DOT Delta ACRO Mount: If you are running an ACRO P-1 or P-2 as a backup, this extra-high 2.26" riser mount ensures your sight picture easily clears forward-mounted lasers, gas masks, and night vision gear.

DOT EHS-1 L Holographic Sight FAQs
What is a holographic sight?
A holographic sight uses a laser to project a floating reticle over your target. This lets you aim quickly while keeping both eyes open.
EHS-1 vs. EHS-1 L: What is the Difference?
The main difference between these two holographic sights is how they attach to your weapon. The original EHS-1 uses a Quick Detach lever so you can remove it fast. The DOT EHS-1 L holographic sight replaces that lever with a tough cross-bolt rail attachment for a permanent fit. This upgrade gives the "L" model a lower profile and a more secure connection that will not come loose during heavy use.
Feature Comparison
| Feature | Standard EHS-1 | DOT EHS-1 L |
| Mounting System | Quick Detach Lever | Permanent Cross-Bolt Mount |
| Optic Profile | Standard Height | Lower Profile |
| Targeting Reticle | 1 MOA Center Dot & 65 MOA Ring | 1 MOA Center Dot & 65 MOA Ring |
| Power and Runtime | 1,000 Hours with Dynamic Wake | 1,000 Hours with Dynamic Wake |
| Durability | IP68 Waterproof, Aircraft-Grade Aluminum | IP68 Waterproof, Aircraft-Grade Aluminum |
What makes the EHS-1 L different from a traditional red dot sight?
Instead of bouncing an LED light off the front glass, it uses a 650nm laser to create the reticle. This design helps you focus on the target rather than just the dot.

What reticle does the EHS-1 L use?
It features a small 1 MOA center dot surrounded by a larger 65 MOA outer ring.
What are the benefits of the 1 MOA center dot and 65 MOA ring reticle?
The large 65 MOA ring helps your eye find the center quickly for fast aiming. The tiny 1 MOA dot allows you to make very precise shots at a distance.
Is the EHS-1 L suitable for close-quarters engagements?
Yes, the wide window and large outer ring give you the perfect balance for rapid target acquisition up close.
Can the EHS-1 L be used effectively at longer distances?
It performs very well at range. The 1 MOA center dot allows for long-range precision without covering up your target.
Is the EHS-1 L compatible with magnifiers?
Because it has true 1x magnification and unlimited eye relief, you can easily pair it with a separate magnifier for longer shots.
What is the optical centerline height of the EHS-1 L?
The optic has a centerline height of 2.26 inches.
Why does the EHS-1 L feature a 2.26-inch high mount?
This tall height keeps your head up in a more natural position. It provides maximum situational awareness and makes aiming much more comfortable.
How well does the EHS-1 L work with helmet-mounted NVGs?
The 2.26-inch centerline makes it easy to look through the optic while wearing night vision goggles. You do not have to strain your neck to see the reticle.
How long does the battery last?
The battery provides 1,000 hours of continuous runtime on medium brightness. It also features a Dynamic Wake function and an auto-shutoff to help save power.
Is the EHS-1 L suitable for tactical, competition, and recreational shooting?
This optic is built from aircraft-grade aluminum and is engineered for professionals in the most rigorous tactical environments. It is tough enough for duty use, making it excellent for competition and recreational shooting as well.
