Another consideration when programming in learn mode is that coins at an angle will give a different signal than a flat coin. You increase your chances of finding a coin on angle if you learn with med or large cursor. But this will also allow some trash in (aluminum, pulltabs, screw caps, etc)
If you keep finding the same type of trash at the parks (pulltabs, etc) you can find a clean piece of ground, turn your sens down and teach the expl to reject that item using the small cursor and the "X" icon. After "learning" the expl to reject the trash, most of those items will give a broken signal when you pass over them, while the coins you programmed in should ring out loud and clear.
Another tip is to hunt in your program, then if you get an iffy signal switch to iron mask as see where the cursor falls. But my advice is if it sounds good dig it. Unless you have one of every coin minted you'll never have every coin programmed in your machine. Not to mention the buttons, bullets, and jewelry you may come across.
My first competition hunt I used my "learned coin program". After the first three rounds I wondered why I didn't find any silver rounds (1 oz coins). I was lucky enough to win one by finding a token-and guess what? The big silver hit to the right and down about a quarter inch, OUTSIDE OF MY FLAWLESS PROGRAM! I was stunned, but bagged a few the following day.
I detected for 13 years with low to midrange machines made by the "other" manufacturers. Never found any gold and only a few silver coins. The first time I took my Excalibur out I bagged my first THREE mercury dimes. The first time I took out my Explorer I bagged a fat 14K wedding back and a buffalo nickel.
You have the best there is out there! Dig em all and you'll be pleasantly surprised!
