I keep a notebook of hunt information and when I first started out a, 4 hour, 16 coin day that netted me 2 bucks got 3 exclamation points!!! I stumbled around for about two weeks after that wondering if I would ever have that good of a day again. Then I hit this elementary school and found 40 coins in 70 minutes for almost 8 bucks. It will happen to you too. I hunted that school over and over and I still like going there. On about my 10th hunt there I found a 14k mans wedding band. You really never know. Had a hunt there this January and found another almost 5 bucks. It's the location! If anybody has ever MDed there before me they really suck.
I am running out of attainable goals. You see normally my knees give out at 3 hours. Sometimes I can make it to 4 but rarely more. I have had two 200 clad coins day, one $25 in clad day. My next goal is a roll of each US coins in one day. The nickels will be really tough. My best ever day was two silver rings, a gold ring, and two standing liberty quarters and about 150 clad coins (thats a long morning hunt, followed by a long nap, followed by a long evening hunt, followed by two days bed rest.)
I credit finding this forum for motivating me. I see a guy find a gold ring and I say why not me. I see somebody find 50 quarters and I say why not me.
Find a play area at either a school or a park that has one of those huge wooden (or metal) jungle gyms. The ones with bark chips or ground up tires are best. Do a thorough job. Swing slow. Get under the equipment and as close to metal polls as the 250 allows. It will hone your skills and you'll find a lot of stuff. Coins, toys, jewelry, bullets, pipes, zippers, buttons, hair clips....... Some foil, pull tabs and junk but typically not too much. The best thing is you can go back in a month and find just as much loot.
My final word of advice. Depending on the size and alloy of a ring they can indicate all over the scale. If you get in the habit, like I did, of notching out too much to avoid the junk you will also leave the gold for the next guy. I found 6 gold rings with my 250 and they rang up on either nickel, or the two spots to the right. I found one very small gold ring with my 2500 that rings up below nickel (foil) on both my 2500 and 250. One gold ring makes you forget a whole pile of clad coins and better yet a whole pile of pop tops and screw caps!
Good luck.
