SEARCHCOILS
Selectingthe
right
searchcoil forthe
type
ofdetecting
you
are doing
will add
greatly
to
your
success.
The
STINGRAY II
is
equipped with
an 8
"
open center
Concentric
style
coil. To
increase
the flexibility
of
your
STINGRAY
II,
Tesoro has
designed it
so that the
searchcoil is replaceable
by
the user.
Optional
search coils
of
4",7",and
lïW
areavailablethrough
yourdealer.
The
8" unit
furnished
as standard
is
probably
the
best
overal I
coil size for use
by most
people,
since it
offers the
best
compromise
as
far
as depth
vs. target
size is
concerned. For
people
who need
to fi n
d targets larger
than
co
ins,
th e I
0 Yz"
cnil
will
grealy
increase
detection
depth. For fi nding
smaller
pieces,
such
as some
jewelry,
the 4"
ot 7"
coil will increase
the
detectors response
to smaller
targets.
