I use the pouch that came with my Excal. Its a one pocket pouch, but I always put my trash in with the good stuff, then I go through everything at home. I have found many things that I thought were trash, but after careful examination, they were keepers. I dont like to waste my hunting time, by examining every find, low tide waits for no one! Besides, I like to collect different types of trash, so I can try to figure out the different tones, which I havent yet!
I know a lot of people like to dump the trash in the nearest trash can, but I think it can wait till I get home and have more time. My first diamond ring looked like junk, and it was a month, before I knew what it was. Now I keep all the rings, and on my off days, go through them, looking for keepers, I never throw out junk jewelry or give it away, until im 110% sure of what it is, then check it again!
