EHS1 Holographic Sight Review — Is the DOT EHS-1 Worth It?
Posted by DOT on Oct 13th 2025
If you’ve been looking for a new holographic sight that rivals the EOTech EXPS3 without breaking the bank, the EHS1 from Dynamic Optronic Technologies (DOT) deserves your attention. In this in-depth review, 2A-N-LA puts the EHS1 through its paces, comparing it directly against big-name optics like the Vortex UH1 and EOTech EXPS3.

First Impressions
2A in LA has tested dozens of optics — from pistol dots to full rifle optics — and the EHS1 immediately stood out for its build quality and design simplicity. Mounted on a Daniel Defense Mk18, the setup was intentionally stripped down from a more complex Vortex UH1 + magnifier combo. The goal: see if the EHS1 could deliver top-tier performance in a smaller, lighter setup.
“The EHS1 felt like a tank — rugged, clean, and purpose-built. It reminded me of the EOTech in terms of performance but at a fraction of the price.”
EHS1 Key Specs
- Magnification: 1×
- Reticle: 1 MOA center dot with 65 MOA circle
- Body Material: 7075 aluminum, anodized finish
- Battery: CR123A — over 1,000 hours on medium brightness
- Waterproof Rating: IP68
- Weight: ~260g (without battery)
- Mount: Integrated Picatinny mount with included riser
Performance & Value
The EHS1 retails at $599, positioning it as a mid-tier holographic sight. For context:
EOTech EXPS3: $819 + $100 riser = ~$919 total
Vortex UH1: ~$959.99 without riser
That means DOT’s EHS1 delivers similar functionality and build quality for $300+ less than a fully set-up EOTech.
“It’s not an entry-level optic — but it’s giving me everything my UH1 and EOTech give me, at a few hundred bucks less.”
During testing, the optic:
Held zero after 1,500 rounds of .223/5.56
Showed no drift or loss of zero
Offered fast target acquisition and clear glass
It was easy to mount and adjust
While the optic hasn’t undergone drop or torture testing yet, the aluminum housing and IP68 waterproofing inspire confidence.
Night Vision Compatibility
The EHS1 is night vision capable, making it a legitimate competitor to high-end EOTech models. 2A N LA plans to run the sight under NODs (night observation devices) in an upcoming episode to test brightness control and clarity in low-light environments.
Design & Ergonomics
The EHS1 has a boxier, more modern look than the rounded UH1 or EOTech housings — something 2A in LA says “grew on him” after time on the range.
“It’s very reminiscent of an Acro P-2 — more squared-off, but clean. Functionally, it’s solid.”
The optic’s simple layout and integrated riser make it easy to integrate into AR setups without extra hardware.
Final Thoughts
“They didn’t pay me to say any of this. DOT gave me the optic to test, but I didn’t need it — I already had high-end gear. This was about bringing awareness to a U.S.-based company making quality optics right here in California.”
The DOT EHS-1 stands as a legitimate EOTech alternative — offering durability, clarity, and features at a lower price point. It may not yet have the long-term track record, but it’s a promising, American-made option for shooters looking to stretch their dollar without sacrificing quality.
Conclusion
If you’re in the market for a holographic sight with EOTech-level performance and $300 in savings, the EHS1 from DOT should absolutely be on your radar. As 2A in LA sums it up:
“It ran like a mofo — and it’s giving me everything my other optics do, for less.”
