I don't have the 6 but I have two of the Eliminator 3s. The glass is dark due to the laser going out and coming back in. There's a lot going on in there. So very early and very late it can be hard to see like is possible with great glass. However, I've made 300+ yard shots at last light. It's my understanding that they have greatly improved that aspect. But if you want the best glass for $2400, it won't be in the Eliminator.
IMO, they are as good as it gets for open country called coyote longish shots. The speed you get a firing solution is unmatched, I've tried separate rangefinders and dialing for years and IMO it's just too slow. I'm constantly looking for good deals on used ones and I'd love to have the new 6. Spend the time to dial it in and test it out thoroughly.
