Very small frequency detectors run on just one frequency at any given time. In line with Lubbert and Ross, they’re manufactured for entry-degree hobbyists searching for coins and jewelry, but won’t do the job perfectly for gold prospecting or scanning saltwater beaches.
When you finally ascertain the focus on’s site, dig a small plug and use a handheld pinpointer to precisely Track down the focus on throughout the plug.
