Well I did a post not long ago where I was out with a noob by some baseball & soccer fields. It was his first hunt. When he dug something and held it up, I tried to shield the sun with my left hand to get a better see what he was holding over there - whack!!!! Someone drove a golf ball from the other side of the tree line and it found my left hand. I thought it broke my hand - yes went to see a doc. It hurt real bad. I am still recovering from that one. I can now hold a cup of coffee but it's not comfortable to do so. I was supposed to go back after the swelling went down but haven't. He wanted to make sure it was going to be okay, I figured he wanted to do more damage to the medical bill.
My right hand was injured 13 months ago but that was not during metal detecting.
I can't swing a light weight detector for long at all right now, only for a few very short sessions. So the heavier and off balanced detectors is something I can't do for awhile.
So the last bad day wasn't a dark cloud, it was that stupid golf ball that arc down from the sky.
My point is, I don't care if all I find is a tab. And if find at least just one penny, that's a bonus. When I do find silver coins etc, those are jackpot days. No matter, if I make it back without something happening to me, my gear, or my vehicle, and have something in the goods pouch, then at least I'll call that a good day.
I do have days where I bring home nice relics, or silver or jewelery - those are the ones that keep me going. If I let a few incidents stop me, then I would have gave it up about 25 years ago when a dog didn't like me swinging a detector. That's the disadvantage of using over the ear headphones and not knowing an angry dog was coming to let me know he didn't like strangers swinging a detector. Well I didn't give it up back then when that happened.
