Tips on using the MD20
 Some users have complained that the knobs are too easy to accidentally bump out of adjustment.  One easy fix for that is to buy 2 small O rings, the type that can be found in a hardware store.  Remove the knobs by backing out the screw in the side of the knob, then pulling the knob off the shaft.  Slide the O ring down over the shaft, replace the knob on the shaft and tightening the screw.  Adjust the knob up or down on the shaft/O ring to get the tension you prefer.  This will have no effect on your warranty. 

There is some uncertainty on how to use the sliding copper ring on the probe..  A good analogy might be the focus ring on a flash light.  When the copper ring is on the balck line you get a wider beam.  When the copper ring is pushed toward the red lline the beam gets more narrow.  When the ring is pushed beyond the red line the beam collapses and the unit will continue to sound.  For better stability set the copper ring on or near the black line.  If  you are unable to slide the copper ring to the red line, your unit may need to be calibrated, if so please call us at 480-396-1181 M-F between 9 and 5 MST.

Pictured nuggets found
in Arizona with a

Paul found this 1/2+ ounce nugget this past August while working a claim in central Arizona.  The 5 smaller nuggets pictured were found in the same area a short distance from the large one.  The Falcon located and pinpointed the large nugget at a depth of 12 inches!  Paul was shocked and so was I.  Generally speaking, I might expect the Falcon to pick up a beer can at 12 inches but not a half ounce nugget.  And since many larger detectors have been used in this area why hadn't they found it?
After considering the factors,  I suspect the nugget was setting on end and had an oxidation layer (halo) which was detected by the Falcon.  If it was setting on end, the oxidation layer might look like a distorted football setting on end.  Since the oxidation layer and the nugget are electrically conductive, the target would appear larger than the nugget by itself.   Of course once the nugget is dug up the oxidation layer is destroyed.  That oxidation layer may have taken several millenium to form, so reproducing the conditions of this find is nearly impossible.
The oxidation layer (halo) effect is noticable in coins in a few years and in iron in a few months, but since gold does not oxidize very fast, it takes many years.  Many nugget hunters will tell you that they quite often dig a respectable target only to lose it when they dig it up.  The target by itself may be too small for their detector to locate.  Having a Falcon handy makes locating nuggets easier and may locate those "lost" ones. 
Remember most nuggets we find may have been setting right there waiting for us to find them for hundreds of thousands of years.  Pretty awesome when you stop to think about it!
