If your friend or his wife wears glasses, the Andrews 8X42 semi-APOs are very good because of the long eyerelief. You can still see lots while wearing glasses. The Andrews 10X42 semi-APOs are also good, but one can't really wear glasses with them.

Kogan sell a reasonable pair of 8X42s with long eye relief for $65 during their specials (I even got mine with free delivery), but they aren't as good at the edges as the Andrews ones.

But if your friend only really intends to use them during daytime, a small pair of 8X20s or 8X25s will be fine. Best avoid 10X25s, they can be good but because of their lack of weight, they always shake.

Most important thing to tell your friend is that if he goes into a shop, he picks up binoculars, adjusts the left eye with central focuser, then adjusts the right eye with focuser on the right eyepiece. Then look at something in the distance through windows, and alternately open and close left and right eye to see if the image stays steady or jumps around. I've seen $200 pairs of brand new Tascos that failed that simple collimation test.

Also, as he compares different pairs of binoculars, he'll see one or more pairs where the image is clearer and "pops" (much better contrast). Those are the pair he wants. I even have a little pair of Bushnells that deliver nice images like that.
