If you are going to be hunting with Radio's It might be worth getting the all in one, Some other guys in the group had them (not sure brand) but it is one less thing you have to carry if you plan on using handhelds. I remember wishing I had that option instead of carring both. I do not not know the details of the bells and whisles that came in it, but you should check into.

Throwingstarr is right about the compass feature, it's awsome, you would want that option.
