Welcome to T'net and the Wonderful World of Treasure Hunting
from a fellow Washingtonian!
I'm not familiar with your machine, but just remember to have fun! The more you practice, the better you'll get at 'hearing' what your MD's telling you. But if you've read many of the posts here, they tell me gold jewelry sounds like pulltabs

(Don't know from experience... haven't found any yet, myself

)
Hey! You've already found a penny! Better than I did on my first hunt... and it just gets better!
I've had a great time hooking up with some of the folks from this forum and learning as we go. There was a good video on one of the posts here that showed how to cut a decent plug so we don't leave a mess. Maybe someone remembers where that post was? It was posted by a teacher. Anyway, most of us take quite a bit of care to leave a site better than we found it so as to not give MD'ers a bad reputation. Hope you decide to join us in this effort. The more respectful we are, the more respectable our hobby becomes, the more access to sites we get, and the less hassles.
Have a great time learning your new machine, be ready to dig a lot of Junque, and give a PM if you're going to be in NW WA and want a hunting buddy.
