The “DSP inside” our SPECTRA long range locator does it all:
it makes millions automatic corrections to the output frequency when it operates,to match the metal programmed, and produces a signal accurate to 0,1 Hz. The result? only the selected metal is stimulated and no faults.

Digital Frequency Synthesis:
scan for gold, silver, copper, bronze, iron, lead, aluminum, diamonds, water, void & other elements.
User can fine adjust the frequency at 1 Hz steps.
Digital Ground Balance:
analyses ground conditions and automatically selects and visualizes the appropriate waveform to avoid false readings from minerals.
With the “GROUND BALANCING” function.
SPECTRA analyses both the soil mineral content & level of wetness,
the result appears as GROUND VALUE identification number, on a scale 00 to 99.This identification number informs the user of the ground type to be scanned.
Auto Power On to the ground - APO:
SPECTRA long range locator has no “POWER ON” key. it makes a check to the ground conditions, and turns on automatically only in good conductive ground, that absorbs the signal.
SPECTRA needs not any probes, cables, filters, external battery: It is a compact design easy to handle. It detects to all directions. The signal transmits in a 360 degrees radius, the user is not limited in one direction.
