Great job on the silver, man! Those machines have a nice response time and good depth.
I'll leave this here. It's from another user on some forum. I had it saved on Word. I thought you may find it interesting.
Xterra Stock coil - Measuring Mineralization
Procedure in Normal GB mode with GB Tracking "OFF" and Sens=20:
A. Auto-noise cancel in the area you will hunting with the coil held 3 feet above the ground and parallel to it.
B. Locate a target free area of soil.
C. Engage Normal GB & remain in the GB screen.
D. Place coil on the soil. Do not press the coil against the ground! This will distort the coil shape and give an inaccurate result. Simply allow the weight of the machine to lightly keep it against the ground.
E. Press the Auto GB button and raise coil about two feet above the ground before Auto GB has completed. If by the time you reach the apex of pulling the coil up to two feet it doesn't complete, then pump up and down from just above the ground to two feet high as accurately as possible. Recall that Auto GB signals with a tone when completed.
F. While still in GB mode press and hold Patterns button to get the numbers. The numbers are six digits in length but read out in three groups of two that will repeat if the Patterns button is held down. Therefore 99 99 99(almost a million) is the largest number possible and 0(00 00 00) is the smallest. Forty-six thousand would appear as the following sequence, 04--60--00. Make a note of the numbers which we will call the "IRON NUMBER"(Magnetite...Black-Sand).
G. As a reference, numbers in the thousands are mild ground, medium grounds tens of thousands , and hot hundreds of thousands. For clarity:
1. 0(zero) >> 10K mild ground.
2. 10K >> 100K medium ground.
3. 100K >> 1M hot to scorching.
Procedure in Beach GB mode with GB Tracking "OFF":
The same as above in normal GB except that your are measuring conductivity. Great for Ocean beaches, salt flats, & dried up lake beds etc. I would also take three samples in the exact same spot and average them to get an average number, using either of the above procedures.
