LASER RAPIER II OPERATOR INSTRUCTION MANUAL
Performing the Audio Battery Test
Your Rapier II is equipped with an automatic battery test circuit
so that you can always be sure you are getting top performance from it.
The battery should be checked after the detector has been on for about
10 minutes and then periodically if you are using it for long periods.
To activate the Audio Battery Test, simply turn the detector off
momentarily and then back on again. If the battery is fresh, the detec-
tor should emit a continuous and loud “beep” sound that lasts for about
4 or 5 seconds, and then slowly fades into silence. As the battery ages,
this sound is less intense and fades out more quickly. When you hear
only a brief “buzz” or no sound at all, replace the battery with a fresh
one.
If you prefer, a rechargeable Nickel-Cadmium (Ni-Cad) battery
can be substituted for the standard 9 volt alkaline battery. Individual 9
volt size Ni-Cad cells, as well as the chargers for them, are readily avail-
able at most electronic supply stores. They are installed into your de-
tector in the same manner as non-rechargeable batteries. The battery
test sound on a Ni-Cad will be weaker than an alkaline in the beginning,
but will not weaken as much with use.
Handling your detector
The detector should be held in a position that is comfortable for
you as shown in the ADJUSTING THE POLE & SEARCHCOIL sec-
tion in a three foot arc, overlapping succeeding strokes well. This mo-
tion is called a “sweep.” The Rapier II was designed to get maximum
depth without the frantic pace required of earlier motion detectors, so go
at a pace that is comfortable for you. In fact, trying to hunt too fast may
even cause a loss of depth in heavily mineralized locations.
Regardless of which mode you are using, try to keep your
searchcoil height constant and close to the ground. Most people tend to
raise the coil at the end of the sweep-much like a pendulum-especially
if they are hurrying. Try to avoid this, as any increase in height from the
ground will cause a corresponding loss of depth.
1)
On the lower pole assembly, remove the mounting screw and
thumb nut from the black nylon pole tip.
2)
Insert the pole tip between the mounting ears of the searchcoil
and align the holes of the pole tip and washers with those of the mount-
ing ears.
NOTE: the pole tip should fit very snugly unto the mounting ears; however, it
may be necessary to use the thin friction washers instead.
3)
Insert the mounting screw through the holes in the mounting ears
and pole tip-entering from the side opposite the cable connection.
4)
Install the thumb nut on the mounting screw and tighten by hand.
(NOTE: Do not overtighten the thumb nut. It should be snug, but not too difficult to
loosen up.)
5)
On the upper pole assembly, depress the two spring buttons and
slide the middle pole assembly into the upper pole assembly until the
spring buttons click into the hole-locking the two assemblies into place.
Tighten the pole lock to secure the two assemblies together.
