I have never used the 9x40 Bighorn in the field but have looked through them in the store a few times. If you could get them cheap enough they would be ok but if paying full retail, there are better binos for the money. I have 3 pairs of Steiner binos and have quite a bit of expereince with Steiner and the only Steiner binos I would buy are the ones that are mil-spec rated and come with the 30 year warranty.
