I am 55. Started hunting at about 30. It appears that most folks have to mature to be comfortable with this hobby because of so many things that age and the hobby have in common.
It requires patience.
It requires ethical conduct and responsibility.
It requires committment to be good at it.
It requires some reasonable funding to purchase some good equipment although this is not a major hurdle today with some great low end detectors with high end features.
I guess I could go on and on but the fact is that you don't usually see all those things in a very young person. Not to say that ther aren't older people who struggle with those things also but to find a young person who doesn't have other priorities that would trump treasure hunting is rare. After all, there are girls, boys, cars, clothes, sports, more sports, more girls, more boys and did I mention cars! It is the same reason you don't see a ton of Eagle Scouts running loose on the world. The ones that are that mature at such a young age are rare indeed.
Would love to have you join us whenever you come to Florida. Bet I can out hunt yah!
Good Luck and welcome to a great hobby.
DaChief!
