Excellent rangefinder for the price!!! - Vortex Razor HD 4000 7x25mm GB Ballistic Laser Rangefinder

I hunt and shoot in the midwest and this thing gives me all the data I could ever want to take down any critter in the farm fields here. Just tested it out in a boar hunt in Tennessee and ranged, dialed and hit that pig at 300 yards on the first shot. Very happy with this product so far!! Only small down-side is that it does take some time, research and testing to really make sure that your ballistic profile is accurate and you'll need access to a chronograph to accurize everything. But honestly, if you are looking for an accurate ballistic calculator you will need to do all of that no matter what unit you purchase.
