Description
The H2S is a 1x holographic weapon sight built from CNC-machined 7075 aircraft-grade aluminium with a hard black anodised finish. The large 30.5 × 22.5 mm effective window and the 1 MOA dot with 65 MOA circle give fast, both-eyes-open target acquisition at close and medium range.
Power efficiency is the headline specification: a single CR123A cell provides at least 1000 hours of continuous operation at medium brightness. The sight is rated to 1200 G shock and IP68 sealing — IP68 meaning it will survive full immersion, not just rain.
Why the H2S
- 1000+ hours runtime from one CR123A at medium brightness — months of field use, not days.
- IP68 + 1200 G — full immersion protection and the highest shock rating in this class.
- 7075 aircraft-grade aluminium, CNC machined with a hard black anodised finish (not painted).
- 1 MOA dot with 65 MOA circle, parallax ≤ 2 MOA for accurate holdover.
- 20 daytime / 10 night-vision brightness levels, with a reticle flash warning below 5% battery.
- Quick-release Picatinny mount — remove and re-fit without tools.

Frequently Asked Questions
What does IP68 mean in practice?
IP68 is a full immersion rating, not just splash or rain protection. The sight will continue to work after being submerged.
How long will one battery last?
At least 1000 hours of continuous operation at medium brightness on a single CR123A. The sight also powers off automatically after 4 hours of inactivity to preserve battery.
Is the H2S compatible with night vision devices?
Yes. It has a dedicated night-vision mode with 10 brightness levels designed for use with night vision equipment.
What is the click value?
0.5 MOA per click, with ± 40 MOA of adjustment in both elevation and windage.
Is it painted or anodised?
Hard black anodised — not painted — so the finish will not chip or flake in field use.
Is OEM/ODM supply available?
Yes. Contact ERDI-infrared with your branding and volume requirements.
