The

detector

is

now

excluding

the

ground

at

a pre·set level

on

one channel and

discriminating

at

a

programmed level

on

the

other

channel.

All

metal objects

will

be indicated

by

an increase in loudness

but

rejected objects

will

cause

the

meter

to

fall

to

the

left

and

the

tone

frequency

to

decrease. Accepted targets

will

conversely cause the meter

to

rise

to

the

right

or

remain

stationary

and

the

tone

frequency

to

increase.

Searching

Simply

sweep

the

detector

in an are, ensuring

the

head

is

level and

as

close

to

the

ground

as

possible.

Advance

half

a head length

at

a

time,

and ensure

the

tuning

level is

correctly

set

by

raising

the

heed an

inch

or

two,

depressing

the

push

button

re·tune. and

then

lower

the

head and

continue.
