To Assemble
1. Remove all parts from shipping carton (see diagram next page).
2. Use nonmetallic washers (between round search coil and clevis
ber rod), and ber bolt and thumbnut to secure search coil to ber
rod.
3. Unlock Camlock on “S”rod, insert ber rod into curved rod, line up
buttons into one of adjustment holes. Twist Camlock to LOCK.
4. Unravel search coil cable and wind around rods (rst revolution
over top of rod). Plug search coil cable connector into control box.
Screw nger tight to secure. Secure cable to ber rod near search
coil (rst revolution) with small hook and loop strap provided. Allow
slight cable slack (prior to rst revolution) to allow search coil tilting.
5. Grip by handle, with arm in elbow cup, and sweep search coil over
oor. If necessary for comfort, unlock camlock, compress buttons
and reposition ber rod. If necessary, elbow cup is also adjustable for
comfort.
6. A large nylon strap is provided. When woven through the slots in
the arm cup, additional leverage is provided. Insert smoothest sec-
tion rst (left slot for right-handed individuals, right slot for left-hand-
ed individuals) hook and loop facing up. Fold tab at end of rougher
loop into “T” to lock this end. Insert opposite end through second
slot so arm can be inserted and removed from arm cup without
readjustment of strap.

Batteries
1. Open battery door by pressing elongated button on back of
display and ipping open door.
2. Install two 9-volt alkaline batteries taking note of (+) and (-) posi-
tions (only t one way), close door.
3. Press ON/OFF button.
4. Batteries that are weak, or become weak during use, will au-
tomatically indicate Low Batt. with a battery icon on the left center
portion of the display. Replace with two good quality alkaline 9-volt
transistor batteries. Low volume beep, without a Low Bat display
indication, requires only the one battery on the headphone jack
side of the compartment be replaced.
5. One may expect about 20 hours of continuous searching with
two good quality alkaline batteries. Battery life will vary with inter-

mittent use, temperature, control settings, target indications, battery
quality, battery condition upon purchase, and shelf life. One may add
or subtract as much as 50% depending upon the above variables. It is
always wise to carry back up batteries when traveling far from home.
6. Good quality rechargeable transistor 9-volt batteries may be
purchased separately for use in your Prizm. Typically rechargeable
transistor 9-volts will fall short of 20 hour continuous search time by
as much as 30%. Expensive types may exceed this alkaline life rating.
Either way their rechargeable option is desirable for avid (everyday)
searching. White’s Electronics, Inc. has chosen not to compete in the
transistor 9-volt rechargeable battery market. We would suggest
common reputable brands and retailers for such systems.

Getting Started (Prizm™ II, III, IV, V)
1. Once assembled with good batteries installed, press ON/
OFF.
2. Due to the many metals used in modern construction it is
best to use and practice outdoors.
3. Sweep the round search coil from side to side over ground
evenly (near to or touching ground surface) keeping it very
close to the ground throughout each pass and overlapping
each pass as if mopping a oor. About two seconds per pass
from left to right, and two seconds returning from right to left
is necessary for the Prizm to perform as designed. Sweeping
too slowly (signicantly less
than two seconds per pass)
will deter good performance.
It is also necessary for the
round search coil to be mov-
ing (sweeping) for the Prizm
to detect and identify metals.
Once an interesting signal has
been located, (Step #6) the P/P
(pinpoint) button can be used
to allow much slower search
coil movement isolating exactly
where to dig.
4. Solid repeatable beeps and
repeatable display after several
passes indicates an interesting
metal target.
5. Broken, sputter, or inconsistent beeps and display, indicates

⇠
Prizm™ II • III • IV * V
likely uninteresting metal targets. Ignore these targets.
6. Once a solid repeatable beep and display indication are lo-
cated, press P/P button and“X” area to pinpoint exactly where
to dig. Press P/P again to continue searching.
7. Sweeping the round search coil over the ground, recogniz-
ing solid repeatable beeps and display indications from broken
or inconsistent ones, pinpointing, and digging all take practice.
Be patient. To speed the learning curve bury a nail, coin, and
other items an inch or two in the ground and practice locating,
recognizing the dierent sounds and display indications, and
pinpointing.
8. You must have permission to search both public and private
property from the owners or person in charge of managing
the property. In most cases, you can locate the owner through
City Hall or the County Seat. It is important for the future of
metal detecting that you take care in digging. Unsightly holes
are dangerous to people and livestock as well as detrimental
to continued use of detectors. Fill all holes and remove all
trash you encounter. Some areas have restrictions on the size
and type of digging tool you may use which may present ad-
ditional challenges. Check with your Dealer, Area Detecting
Club, Local Police, or Parks & Recreations Department.
9. Known and marked historical sites are certainly “O Limits”
to metal detector use. Educate yourself, follow the laws in your
area, and always aid Law Enforcement and Archeologists to
further promote this great hobby. With research and thought,

Prizm™ II Controls
1. ON/OFF turns the Power ON and OFF. Batteries that are
weak, or become weak during use, will automatically indicate
Low Batt. with a battery icon on the left center portion of the
display. Replace with two good quality alkaline 9-volt tran-
sistor batteries. Remove batteries for storage beyond two
weeks.
2. SENS (sensitivity) adjusts the responsiveness to metals,
ground, and external electrical interference. The Sensitivity lev-
el is continuously shown on the display. The further to the
right the ll towards taller bars, the higher the selected sensi-
tivity setting. Use the SENS Up arrow button to increase, down
arrow button to decrease. Use the highest level that behaves
predictably. Use lower levels for areas the Prizm™ behaves un-
predictably or is unstable (false signals without the presence
of metal). Areas of high power electrical lines or extremely
mineralized soil conditions will likely require lower SENS levels.
Areas of little electrical activity, and dry beach sand, usually
allow high SENS settings, and thus more detection depth.
Standard settings work well in typical conditions.
3. P/P activates pinpoint mode for better item location. P/P
can also be used for searching when iron and steel is de-
sired as well as all other metals. Once P/P has been pressed
(tapped) all types of metals respond with a beep that is basi-
cally the same. No adjustments can be made while in the
P/P mode. Press a second time prior to continued searching
to return the Prizm to Discrimination, which varies the beep
according to the DISC setting. Holding the P/P button during
pinpointing allows automatic return to Discrimination search-
ing when released. P/P status shown on display center.
