Range of business radios

Being new to the forum I am looking for a business radio with a good range.
as well as rugged. What is a reasonable range (outdoors) for the Blackbox models?

They will get two miles on average. Depending on line of site you might get three miles or more but that can vary. For the same price range there are also Icom radios such as these: http://www.buytwowayradios.com/products/icom/ic-f4011-41.aspx

They will also get about two miles, but are a bit more rugged.
