I have some 7x50 Steiners, they are great. I watched the lunar eclipse here last week with them and they were amazing.
BUT they are heavy, I dont take them with me backpacking because of that. They also dont offer enough magnification to be useful on the range, except maybe at 25 yards for handguns.
Id go for the Navigator. I personally have a pentax 8x25 and its great for most of what I do.
