I thought I was going to strike it big when I got into detecting over 50 years ago, but it still hasn't happened. Hahah! I have found some goodies along the way, but have learned a lot too. I still love digging but have curtailed it to only doing it as a sideline to any excursion I make in my vehicle to do something else that has to be done, so no gas expense that can be directly attributed to MDing. I sold my expensive rig & got into a lower value detector, a used one at that, and it does all I need done, and has already paid for itself several times over. Then I swapped over to rechargeable batteries, which do work for me despite the warnings to only use the expensive alkalines in my unit. I hunt in notch, and block out the zincs, but still dig nickels and get an occasional gold ring and dig everything 25c & up. Hunting old stuff is fun, but I usually go in the hole with time and money spent opposed to just raking in quarters. You would be surprised at how many you can find if you ignore the pennies and dimes, so more 25c's in the time otherwise spent recovering lesser coins. Finally detecting is paying in a consistent fashion with the bonus surprise gold that comes with the nickels. It's still a peasants game, but fun to rake in a pocketful of oxidized quarters that are so much fun to spend. I'll leave all the other stuff for you fellows to find. Good luck & cheers!!
