Then move the coil away from the target perpendicular to the primary direction

(A) scanning (e.g. forward) along this line

This retraction of the coil in this direction must pass through the original coordinate. Re-

enable the static mode. Scan the object along the line as accurately as possible keeping a

minimum distance between the ground and the sensor. The recorded coordinate of the

maximum frequency tones sound on line B, will determine the exact location of the

object.

MODE “TURBO”

In the "Turbo" mode the search coil operates at the forced excitation current.

This mode allows you to increase the sensitivity of the device and to improve the

immunity of the device from external electromagnetic interference.

Attention! The “Turbo” mode greatly increases current consumption and as

such battery operating time is greatly reduced!

Switch to TURBO and back by using the button while in search mode. It is

necessary to ensure that the settings ST/RT sensitivity and volume on the display

screen are not displayed.

MODE “ECONOMY”

In the "Economy" the sensor operates at the minimum excitation current. This

mode allows you to improve the comfort of your search on soils with a complex and

variable salinity (for example in the surf of the beach), or at locations with extreme iron

debris.

Attention! After switching to “Economy” mode it is advised to ground balance

the device.

For reference, the detection range in this mode, when air testing a large 43cm

copper coin, such as a Victorian Penny, is approximately 35cm (10” DD coil @ 6,5-7 kHz).

Thanks to the significant reduction in the consumption of power in this mode you

can run up to 40 hours on a set of fully charged batteries.

Switching to the turbo is made through the "Extras” Menu, section “Extra

Settings”"(see below).

MODE S ALGORITHM

From our experience we know that the majority of metal detectors react to flat

iron objects as nonferrous. To assist in solving this problem the specially developed S

algorithm is used to assist in properly identifying these targets.

The most effective use of this algorithm is in identifying small flat iron objects (15

cm2), such as beer caps, rusted pieces roof tin, etc., with a signal rating greater than 10.

If the device detects an object with a "questionable" non-ferrous signal (high

tone) and it has a rating over 10 then using the S-Algorithm can help to identify these type

targets.
