#1: Coin and Jewelry Mode. (toggle switch)
#2: Set the gain to around 7-8 (the one you use to turn the machine on)
#3: Set the discrimination around +2. (middle knob)
Dig any positive signal. (I've found small gold rings with a VDI of only 6) Nickels will ring up at 18-20, same as most reg. size gold rings. Higher numbers for a more substantial piece of gold.
Now for the rest of the hunt:
#4: Dig more pull-tabs and can slaw.
#5: Dump pouch contents in garbage can.
#6: Start swinging that coil again.
Repeat numbers 4-6 until you get your gold ring. PLEASE MAKE SURE YOU FILL AND COVER YOUR HOLES THE SAME WAY YOU FOUND THE LAND!!!
(Silver rings have a higher VDI number like pennies, dimes, etc. depending on the weight of the ring)
I'm not an expert on the technology part, so I don't know if this will help you. Once you get to know your machine and play with the settings, you'll find that gold ring. I would start off slow and go for the clad and take it one day at a time. It's an easy turn on go machine and you won't be dissatisfied.
Probably as soon as I press "post message", I'll think of something else I forgot. Maybe the others will help you out also.
Good luck and I'll be waiting to hear about your finds.
