I am thinking about getting a 4800, primarily for relic hunting. Does the 4800 have the same depth as the 5000 ? Dont think I would ever need the other 2 timeings of the 5000. I dont have anyone in my area that keeps these 2 in stock. What is a good price for a 4800? Or would a used 4500 work just as well for my type of hunting? Thanks, Mark
