Hi All,
Just thought I would toss this in. Today, I did some testing on three different PI's trying to compare depth capabilites as well as find the depth limitations on several different size nuggets. The nuggets ranged from about 3 grains to about 1/4 oz. The ground conditions are not as severe as the red clay but are more severe than many gold producing areas I have hunted.
One machine had an 11" round coil, one a 10" round coil, and the third had a 9" by 13" elliptical coil.
When the targets were buried to about the maximum depth capabilities of the machines, I found the machines responded differently. One machine might pick up the target a little better than another when the coil was swept, lets say, east to west or west to east, as a reference, but when swept from north to south or south to north, the other machine might show an improvement.
Actually, I did not try to line up the directions with respect to compass or map directions, but instead, I would walk around the target and try from different angles. All machines were using mono coils.
The directional improvements were not consistent. In other words, a machine didn't always show an improvement lets say, east to west. Maybe on a different nugget, the improvement would be north to south, or someother direction like northeast to southwest.
Basically, this told me an area isn't really fully detected until it has been passed over from several different directions.
Anybody else run into this before? I have had machines show improvements when sweeping from different directions, but have never really noticed that different machines might act differently over the same target.
One more note, the tests were done in town, but there was no obvious electrical interference.
