2. S.A.T. Speed

Self-Adjusting Threshold (auto-tune) smooths the

THRESHOLD, OFF (0), or ON (1-10).

Without S.A.T. SPEED (a setting of 0), changes in

the ground (and the passage of time) will tend to

produce changes in the THRESHOLD sound. The

TRIGGER will have to be squeezed and released

repeatedly to maintain the THRESHOLD. This is

particularly noticeable in non-discriminate modes,

although S.A.T. SPEED will also tend to add

stability to discriminate modes. S.A.T. SPEEDs

1 through 10 will automatically correct for such

THRESHOLD changes.

S.A.T. (auto-tune) is a feature that has been used on

metal detectors dating back to the 1970's. It adds

a loop-motion requirement to modes which are

ordinarily non-motion. It is also known to produce

some variations in the responses to hot rocks (rocks

more mineralized than the surrounding ground)

which change with different speed selections.

Only enough S.A.T. SPEED required to maintain

stability is recommended. Typically normal coin

searching requires slower (lower number) speeds,

beach hunting and relic hunting require slightly

faster speeds (higher numbers), and prospecting

requires the fastest settings (highest numbers).

Tips -

Recommended

for most conditions as it

provides greater stability

particularly in non-discrimi-

nate modes or when sensi-

tivity levels are maximized.

Typically, faster S.A.T.

SPEEDs (higher numbers)

improve performance in

more mineralized ground.

Slower S.A.T. SPEEDs

(lower numbers) improve

performance in milder

ground conditions. Settings

from 0 - 10 are available.
