20-80 X 25?
The usual wisdom is that 10-12 X is about the maximum magnification that you can handle if it's going to be hand held (unless it's stabilising).
25mm is a very small aperture too, and zoom binos have notoriously small exit pupils/fields of view.
Sorry if I'm pouring cold water on the idea, but I think that 10 X 50s are about the best you can do for hand held binoculars.
Of course, try them out. But hold them for a while - see if your hands get too shaky for the high magnification. I find that way too annoying.
