over them. In the Low setting, a long nail will give a good sound from one direction and no sound, or a choppy
sound, from a 90 degree angle. So, pass over all targets from different directions and see if the sound changes.
Small nails, partial nails, or nails that are straight down in the ground will give a good sound no matter what you do.
But there is one more test you can try before digging or walking on. Increase the Pulse Delay up to 17.5 and pass
over the target. A lot of small iron targets will go away at this setting. You may hear a choppy or broken sound but
a nugget will sound clean. The response will be softer and weaker on gold because you have increased the Pulse
hence decreasing the sensitivity to low-conductive targets. This is most effective on shallow targets as most iron is
near the surface. Deeper nuggets may also disappear so I would dig any target that give me a soft mellow signal.
As with any metal detector, there are no foolproof methods of discrimination. Those of us who have coin hunted
have learned the difficulty of trying to determine a gold ring from a pull tab. The same rules apply here, when in
doubt, dig. If you want to find everything, dig everything.
Nugget hunting is the most challenging pursuits one can undertake with a metal detector. There are so many wierd
signals that come from unknown sources and the combination of minerals, salts, and man-made metal in all its forms
is staggering in the types of signals they can generate. More tips will be coming as more people get their feet wet in
the field with this detector.
