Ha good answer d-dancer

Yes we're doing good JUST to pay for our gas and equipment, eh? haha. Even given that you'll get some good numismatic coins, or the melt value of gold if you're a beach or nugget hunter, etc...
Yours & lookin-down's ("no it's a hobby") answers reminds me of this example: When gold hit all-time-highs in about 1980 or so, there was a particular pioneering fellow here in CA, who was amongst the first generation of hunters to figure out how to make metal detectors find nuggets in their natural state (this was before specialty machine for nuggets). He and his buddies were doing good enough on their Saturday/Sunday hunts in the Sierra foothills, that he began to figure out that he was actually making MORE money at gold prospecting, than he was at his job!
As luck would have it, he soon found himself between jobs. So the solution was simple: simply metal detect for a living finding gold nuggets. He did this for several weeks, but soon found that it was no longer fun. Whereas before it had simply been a hobby, yet NOW he was "under the gun" to make a quota each day. So instead of looking forward to it each day (as had been before each weekend), now it was a dread. Now it was paperwork, etc... So he abandoned those notions, applied for normal jobs, and went back to keeping detecting as "fun".
