Any metal detector can find gold. It is the size of it that matters or makes the machine.
My groundhog,running at 15khz,can find gold as small as 1/8th size split shot(.8 gram) for fishing. Air test at 3-4 inches.But,when I put it in the ground,with some mineralization, I cant find it at 1 inch.
Now I have to go up to about 3 pieces of split shot,which weighs 2.4 grams in order to get my groundhog to hit at a couple inches. This is with the stock 7.5 inch coil.
If yours is like elgato,it is 5.5 khz,which is a deepseeker for coins and relics,jewelry. And gold,but just the size will be need to be bigger for your nugget.
Now my Goldmaster,running at 50khz,will find a lot smaller gold. And it has a manual ground balance like my groundhog,and your machine.
Mine can find gold as small as a grain of rice.Or smaller maybe.But again,if the ground is mineralized,my depth goes to crap. And the size of my gold has to be bigger to hear it.
Hope this helps.
But yes,yours can find nuggets,it does have an all metal mode.It does have a discriminate mode.Does have ground balance.
Also go here,and download the 1977 catalog,and the 1978 catalog and see which one has your information,then copy and paste just the info on use,then delete.
