30. 2 Frequency (Best Data)

Transmits and processes data continuously at both

3 kHz and 15 kHz frequencies (salt eliminated).

Automatically chooses to use only the data from the

most reliable frequency (based on both magnitude

and phase) for each speciﬁ c target.

Gold, nickel, and other lower conductive metals re-

spond more reliably at higher frequencies. Copper,

silver, and other higher conducting alloys respond

more reliably at lower frequencies. 2 Frequency

(Best Data) uses the multi frequencymode to can-

cel ground and salt and then selects the most ideal

frequency for that particular target alloy on a target

by target basis.

31. 2 Frequency (Correlate)

Transmits and processes data continuously at both

3 kHz and 15 kHz (salt eliminated). Compares

data at 3 kHz and 15 kHz. Target signals that do

not provide reasonably predictable information at

both 3 kHz and 15 kHz are automatically rejected.

Iron typically doesnʼt compare predictably between

frequencies and thus improved iron rejection can be

expected with the use of Correlate.

Differences in the target signal at 3 kHz and 15 kHz

are predictable regarding valued metal alloys such

as gold, copper silver, etc.. If the two signals do

not match within a reasonable range of predictabil-

ity, most likely the target is not a valued metal and

therefore is rejected.

Multi Frequency Method

Only one of the four available multifrequency

methods, BEST DATA, CORRELATE, 1 kHz,

and 15 kHz, can be "ON" at any one given

time. For example if BEST DATA is "ON",

the remaining three multifrequency options

are automatically "OFF". To turn BEST DATA

"OFF", requires the selection of one of the three

remaining methods. In other words, an opera-

tor never turns "OFF" a multifrequency method,

they simply select the desired method and turn

it "ON", all other methods are automatically

turned "OFF."

The MULTI FREQUENCY selection in use

appears continuously on the bottom of the LCD

display during searching. The ideal multi fre-

quency or single frequency setting will depend

on many different factors such as the amount,

degree, and type, of ground mineralization, the

types of metal alloys most desired, as well as

personal preferences. No one setting will be ide-

al for all situations. A user should ﬁ rst trust the

factory preset settings for the general types of

searching and then experiment to ﬁ nd the most

ideal settings for that particular area and type

of search. Generally multi frequency settings

are better suited to areas that have both mag-

netic (iron) and conductive (salt) components.

Inland areas may vary in this regard with the

soils moisture content. For example dry soil may

present mostly iron type characteristics possibly

making one of the single frequency modes a

better choice. The same area when the soil is wet

may exhibit conditions similar to a combination

of both iron and salt due to nonferrous metallic

type mineralizationʼs greater electrical activity

when wet. For example soils containing silver,

copper, or nickel oxides/nitrates react differently

in conditions from wet to dry. These soil traits

can occur naturally and are typical of areas with

mineral springs or volcanic origins. However,

be particularly aware of this wet/dry phenomena

in farming areas where the soil mineralization is

likely altered for agricultural purposes.
