METAL DETECTOR

INSTRUCTIONS &

LEARNING GUIDE

ASSEMBLY INSTRUCTIONS

Simply follow these instructions to assemble your National Geographic

metal detector and get started hunting for treasure!

STEP 1. Slide the armrest into the back of the handle assembly so that it

sits ﬂush with the handle.

STEP 2. Using a Phillips head screwdriver, unscrew the cover of the

battery compartment, located on the underside of the handle assembly.

Insert 3 AA 1.5V batteries (not included), making sure that they line up

with the positive and negative indicators. Then screw the compartment

cover back on.

STEP 3. Loosen coil knob and fold out the search coil until it angles away

from the shaft.

STEP 4. Turn the shaft nut clockwise to release the telescoping shaft. Do

not extend the shaft past the line indicating the maximum length. Fix the

shaft in place by turning the knob counterclockwise.

STEP 5. Adjust the search coil so that it is parallel to the ground and

tighten the coil knob to keep it in the desired position.

When properly adjusted the coil will sit a few inches above the ground

when you have your arm in the armrest.

QUICK START GUIDE

1. POWER ON

Switch your detector on by turning the

volume dial clockwise until the LED

light comes on.

2. BEGIN TREASURE HUNTING

Swing the coil above the ground in a side-to-side movement.

The detector will beep and the LED indicator will ﬂash when a

metal object is found.

DETECTING HEIGHT Keep the coil 1–2

inches (2.5–5 cm) above the ground

when detecting.

SPEED An average swing speed is

1–2 seconds from side to side.

1-2 in (2.5-5 cm)

SWINGING PATTERN When swinging

the detector, slightly overlap each

swing to ensure areas are not missed.

ADJUSTMENT The detector should be

held straight with your forearm placed

on the armrest.

DISCOVERY When a target is found,

the detector will both beep and ﬂash

the LED indicator.

SENSITIVITY Turn the sensitivity dial

to adjust your detector’s sensitivity.

Increase sensitivity (clockwise) for

more detecting depth. You may need to

decrease sensitivity (counterclockwise)

if there is high electrical interference or

if you get many false signals.

VOLUME Turn the volume dial clock-

wise to increase or counterclockwise to

decrease the volume of your detector’s

signal.

BATTERY When turned on, the LED

indicator will show solid blue. If it is

red, the battery level is low. If the LED

does not come on when you turn the

power on, the batteries are depleted

and should be replaced, following the

safety instructions.

BATTERY SAFETY INFORMATION

• Battery installation and removal should be performed by an adult.

• Be careful to install the batteries with the correct polarity as indicated.

• Do not mix old and new batteries.

• Remove all batteries when replacing.

• Do not mix alkaline, standard, rechargeable, or different types of

batteries.

• Different types of batteries or new and used batteries are not to

be mixed.

• Non-rechargeable batteries are not to be recharged.

• Rechargeable batteries are to be removed from the detector before

being charged.

• Rechargeable batteries are only to be charged under adult supervision.

• Only batteries of the same or equivalent type as recommended are to

be used.

• The supply terminals are not to be short- circuited.

• Remove exhausted batteries.

• CAUTION: Do not dispose of battery in ﬁre. Battery may explode or leak.

OTHER SAFETY INFORMATION

• WARNING: This device contains moving parts. Use caution

when adjusting components. DO NOT lean on detector when in

use as it is not designed to support your weight.

• WARNING: Any changes or modications could void the user’s

authority to operate this equipment.

• The coil is waterproof, but the entire

device is not intended for underwater

use. Please DO NOT submerge.

Metal Detector Code of Ethics:

1. Obey the law. Observe all

federal, state, and local laws

that apply to any areas you

might want to search.

2. Be respectful of other people’s

rights and property. Obtain

permission to search on private

property before you begin.

3. Leave the site as you found it.

Avoid trampling vegetation

and always ﬁll in your holes

after digging.

4. Be responsible with the

treasures you ﬁnd. Return lost

items to their owners if you

can, and resist the urge to sell

artifacts to private collectors.

5. Help further the cause of

archaeology. If you ﬁnd items

of historical signiﬁcance, stop

digging and call your local

historical or archaeological

society before disrupting the

site.

LEARNING GUIDE

Invention and Reﬁnement

The earliest metal detectors were large and inefﬁcient, but

by the 1920s portable versions of the machines began to

appear. The ﬁrst portable metal detector patent was issued

in 1925, and three years later the American businessman

Shirl Herr patented a device that could detect metals buried

as deep as eight feet.

COOL SCIENCE FACT:

In 1974 hobbyist Roy Lloyd discovered a high school class ring from

1926 inscribed with the initials “M.B.” After doing some research he

reunited the ring with its owner, Miles Baker, who had lost it off a pier

in Lake Johnson, Florida, nearly a half century earlier.

These instruments proved their worth when Admiral Byrd

used them in Antarctica to locate materials left behind

by earlier expeditions. Over the next several decades

technological improvements turned the metal detector into a

practical device for hobbyists. Batteries got smaller, circuits

got better, and the whole machine got lighter and smaller

as transistors replaced clunky vacuum tubes. Additional

reﬁnements enabled metal detectors to work underwater

and to distinguish between different metals. Some detectors

can be immersed as deep as 200 feet underwater for

detecting the sea bed, and some even have built-in GPS.

Don't try this with

our metal detector!

It's meant for use

on land only.
