Hi Hammo,
Sorry I didn't see a question.
There could be quite a difference as the Dark Engine uses different bodies, lenses, pill design and components, etc.
The Dark Engine is smaller and lighter than anything else of this type on the market.
There are no artefacts in the beam of the Dark Engine either. It's completely even.
Performance and reach isn't lacking. As the videos show we are getting out to 400+m shootable image at high magnifications even with an add on behind a day scope that has quite poor response to IR. With a decent add on like our Ward D Vision 800L it's getting out 600+m. With a dedicated scope it will go a lot further than that.
I don't think anyone will be disappointed in buying one. But having said that anyone who's not happy can always return it to us within 14 days for a full refund anyway.
Cheers
Clive
