Tell us more like what state will he be hunting mostly. Does he hunt Elk, Pronghorne as well as Deer? What is the terrain hilly, mountainous or flat land. The range finders today are great some have the arc feature which would be great for mountains but not really necessary for flat land. One that will range out to 400 - 600 yards will probably fit his needs. The range finders on the "Black Friday" sales would probably fit what he needs and would save you some money. You can also check out craigs list. Some others might offer some more suggestions but if you answer these questions I am sure some one will suggest on for you.
