Mine got the same reading as my Leica. I do like the speed the leica returns the better and it did range farther. Other then that I like some of the features the Vortex has better. But they did read the same yardages.
You got lucky! I tested Vortex vs all other brands at Sportsmans and Bass Pro and the Vortex was consistently off where the other brands were not. I then called a guy that is associated with Vortex and asked him about the rangefinders as I really WANTED to like it. He told me point blank that they suck and he's associated with them. That was all I needed to go with a different brand
I did hear that apparently they have "fixed" the problem with them being off so bad but who knows, they should have had it "fixed" before they ever decided to enter the market IMO
