This is just my opionion but you still have plug in all the atmopheric condition into your balistic computer to figure out windage at long shots. So if you have to plug it in for windage you get elevation out at the same time. It really only gives you half the information unless you only plan on to hunt when there is no wind. This just seems like add weight to your rifle and that maybe useful in a military application where you do not mind if the wounded critter/person crawls away or not. In a hunting situation it seems like more work since you still have to figure out windage.
