4. Find a place where the soil will be clean, and you will not detect any metal.
5. Press and hold the GG button and move the coil up and down, see. picture. Move the coil from
1 inch to 6-8 inches high.
6. When the GND PHASE value stabilizes at 1 or 2 numbers, release the GG button. Note that
the sound will stabilize when you release the button. After setting, you can stay in ALL METAL
mode or switch to DISCRIMINATION mode.
You can get the most accurate soil values by moving the probe up and down in a metal-free area.
The detector displays two values of soil composition:
1. Type of mineral composition
– GND PHASE
2. Amount of mineralization Fe
3
O
4
– higher amounts of minerals reduce the ability to detect
objects, their depth, ID, etc. These losses are even higher in DISCRIMINATION mode.
The goal of soil composition is to balance the GND BAL value to the PHASE number
PHASE
– measured soil values (two-digit number)
GND BAL
– internal value of the detector which calibrates the soil composition (three-digit
number with a decimal point)
The GND BAL value is measured more accurately, and therefore the value may be different than the
PHASE value.
After finding the value and releasing the GG button, the measured values are transferred to the GND
BAL setting.
The two-digit PHASE number on the display indicates the probable type of mineralization:
0
– 10: Wet sand and alkaline soil
5
– 25: Iron, little soil, you probably moved the coil over an iron object
26
– 39: Little soil, most often beaches, saltwater sand
40
– 75: Red, yellow, and brown iron bearing clay minerals
