After having many testing on this China made UMGD 301ii, I found out that, during my bench testing, it will pick up gold ( it will indicate gold) if I mix up a jewelry of silver and gold. Since silver is a bi product when you refine a gold ore so It is safe to say that tis MD was design to pickup gold ore and nuggets, plus its accuracy on iron, aluminum, and silvers. I'll try this again in outdoor and deeper targets tomorrow.
Have a safe hunting guys....
FYI the vault and pointer gives me a strong signal of Iron and a splats of silver and AU, now my question is why their is a strong signal in Iron when the location of that rock is very isolated? You need to rockclimb a cliff to reach that rock. Pls share your thoughts guys..
