The
Cortes represents all phases of the latest Tesoro microprocessor technology. The
detector combines user-friendly analogue controls with the very latest state of
the art digital signal processing to create an easy to use target identification
unit.
The
simple and functional meter displays an extensive amount of information. The top
row of the display gives you target information on the broadest sweeps of the
search coil, indicated targets falling into one of four categories: Iron or
foil; Nickel, pull tab, ring, zinc penny, screw cap, copper cent, silver coin.
This brief information leads you to the lower rows more detailed information.
The
most prominent feature on the lower row is a nine-segment bar graph. It shows
all of the information that the search coil saw during the complete sweep. Full
sweep data is helpful in determining possible trash/treasure masking and odd
shaped iron. The meter also indicates a peak signal target identification
number. The Cortez will display the largest part of the signal as a two digit
number from 0 to 95. The Iron reading 0 and copper and silver reading up to 95.
By defining the two ends of the scale, higher resolution has been incorporated
into the middle range of the scale the area where pull tabs and gold rings
intermingle. By using the bar graph and peak ID number, you should be able to
visually identify the probable good targets away from the trash.
 To
complement the digital display, Tesoro have added two separate features. The
first, being a three-position notch filter discrimination. Notch allows the user
to eliminate a proportion of the trash target without affecting other good
targets. The second is the Sum Mode. While in this mode the Cortez averages coil
sweeps and activates a multi-tone ID. In use, the coil sweeps should be
shortened to be about 2 to 4 inches. As the microprocessor is analysing the
target data, the ID tones will change. When the tones stop changing, the Cortez
is displaying the most accurate target identification possible.
