When it comes to rangfinders they are definitely not all created equally. Nikon came out with the RifleHunter 1000 last year and they literally could not keep them on the shelves. Everyone of them delivered to a store was gone almost immediately. Heck I do some work for Nikon and I could not even get a pair to try out. Apparently production went into overdrive and they are now available. Not only are they good to 1000 yards but one of my favorite features is the orange LED display for low light conditions. This Rangfinder also has the ID technology, which means it adjusts for Incline/decline shooting positions.
Here's a link to it in case this peaks your interest.
Let me know if you have any questions.
