RE: variable power compact binoculars
I have a set of 8 to 24 power that I use for everything. You can turn them up to zoom in on the 10 ring for 3-d. (there is no power limit in the shoots around here) or you can back the power off for the tree stand. They work just like a variable power scope. I was alittle worried about how clear they were but quickly figured out that like scopes you get what you pay for.
