I know the pictures are not optimal. That has to do with my technological disadvantage. The three pieces on the top tested positive for silver and all sit neatly on a dime. The four pieces on the bottom are not silver but are not magnetic either. The earring is gold at .9g and found six inches down. You can't tell from the picture but it is intricately laced. the round blur at the bottom of the earring is a gold flower. I inserted the settings at which I normally hunt at as well...I put it upside down just to make you think, lol. (aka...technolgically inept.)
Good idea - I have some tiny finds I'll post tomorrow. Appreciate the settings, too. Mine are about the same but threshold about 11:00 and volume way up.
It is interesting seeing others settings on the Sand Shark but you do have to realize, each machine will be different, each user is definately different in hearing capabilities and in how they use and interpet what the machine is saying also....along with that, each beach is different. That being said, find a starting point on you machine and make small adjustments when you find a target to see how it changes what you are hearing. This can be hard for some to do with limited time to hunt for most....
