You have to love pull tabs, and the one sounding machines. I first started out with an Ace 250 which has multiple sounds, and a great starter metal detector. After about a year I bought a Tesoro which is just a one sounding machine. It took me forever to get use to the dang thing. I'm not sure if you are using headphones, but if you are not get some(it saves on battery and will give you better discrepancy between beeps). I have noticed on the Tesoro even though you discriminate you will still pick up a signal, but the signal is "weak" sounding. I'm not trying to insult your intellegence, but your post had no information I could build off of so I'm just giving the basics. Your best bet would be to do a "test" with your metal detector. Get a nail, silver, scrap iron, gold, every denomination in coinage, pulltabs, and other various common crap you find everywhere. When you do this test play will your discrimination, and it should make different tones (thats why I talked about headphones). Some are longer and stronger, and some are short and weak. Your best bet is to stay out of the trashy areas so you do not get discouraged. Although, most of what you find is trash period. There is a very small percentage that you find real treasure. You have to remember that this is a hobby, not a job, not something you do because you are bored, but something that you do for fun and to get outside. You have to dig the trash to get to the good stuff!!!! DIG EVERY TAB SIGNAL ONE DAY YOU WILL HIT GOLD!!!!!!!!!!!!!
