1 Warnings & Safety Information
1. High tension spring loaded device. Always hold device
away from the face and eyes. Never load or activate
pointing towards your body or near other persons.
Always hold your hands firmly over each end of the
eSPEAR when activating out of the water to absorb
tension and to avoid damaging your device.
2. It is recommended that gloves are used when activating
and deactivating the Ocean Guardian eSPEAR.
3. Keep away from children, this device is not a toy.
4. Carefully read instructions before use.
5. Sharks can be dangerous and often unpredictable
creatures and we encourage people to use an Ocean
Guardian when working in, or enjoying the sea, to
minimize the risk of an unwanted shark encounter. While
extensive testing has been performed, and great care
taken to develop and manufacture the Ocean Guardian
range of products, it is impossible to guarantee that all
sharks will be deterred under all circumstances. Water
based activities in the presence of sharks is inherently
dangerous; therefore, we recommend that if a shark is
sighted, the user gets to safety rather than continue with
their water activity.
6. A large pulsing current is emitted from the Ocean
Guardian antenna to produce the protective electric field.
Anyone with any electronic medical device (EMD) such as
a pacemaker, who is pregnant, or has a health condition
which could be affected by the electric field, SHOULD
NOT USE THE DEVICE. Some examples of health
conditions include heart disease, a history of heart
problems, peripheral vascular decease, stroke, a history
of fainting or epilepsy, or lung disease. Users
unintentionally being in close proximity, or in contact with
the antenna, may possibly suffer muscle spasms in
varying degrees; we recommend that users may need to
make adjustments to limit contact in these situations.

7. Positioning of the Ocean Guardian is critical to the device's
performance. Do not attempt to use the device in any way
other than what is described in this user manual.
8. When diving and free-diving with the eSPEAR and
accessories such as the eSPEAR Holster and Carabiner,
use extreme caution to ensure these accessories and the
eSPEAR are worn close to the body and will not lead to a
diver getting hung-up or caught on anything. Any item that
is loose or dangling from a diver can easily become
caught on a reef, cave, boat, part of a wreck, or other
object, which could cause drowning.
9. Ocean Guardian is designed for sea water use only.
10. Ocean Guardian has been designed and tested as a
personal device. Do not attempt to join multiple Ocean
Guardians together or wear multiple devices.
11. Some bottom-dwelling and non-predatory sharks such as
the Wobbygong, Carpet and Port Jackson sharks have
limited active Ampullae of Lorenzini. Therefore, the Ocean
Guardian may have limited or no effect on these sharks.
12. eSPEAR Battery Warnings:
·Do not use any charger other than that specifically
provided for use with the eSPEAR.

3 Introduction
Ocean Guardian is for ocean lovers. It is the world’s only
scientifically proven and independently tested electrical shark
deterrent technology.
Sharks have small short-range electrical receptors in their snouts
used for finding food. Ocean Guardian’s unique three-dimensional
electrical waveform instantly turns sharks away by causing
unbearable spasms in these sensitive receptors.
Trusted by professional adventurers around the world, Ocean
Guardian is a safety device providing peace of mind while
supporting the conservation of sharks. If you’re serious about
adventure, you use Ocean Guardian.
About the eSPEAR
The Ocean Guardian eSPEAR is the world's first hand-held
electrical shark deterrent.
Powered by Shark Shield Technology, the Ocean Guardian
eSPEAR is perfect for diving, snorkelling and spearfishing. Small,
lightweight, easy to carry, and backed by 20 years of research, it
offers powerful and proven shark protection. Simply attach it to
your dive belt, swimsuit or trunks and go!
The eSPEAR features a trigger-activated extendable baton that
creates a powerful electrical field to deter inquisitive sharks or
protect your catch of the day. Once extended the eSPEAR is
automatically ON, with no switches to worry about.
With the eSPEAR everyone can enjoy the beauty of the ocean.
Imagine swimming on a coral reef knowing you have the
protection of proven Shark Shield Technology by your side. One
click and you are good to go.

How does it work?
Ocean Guardian devices generate a protective electric field which
is detected by a shark via its short range sensory receptors called
Ampullae of Lorenzini. These Ampullae of Lorenzini are found on
the snouts of predatorial sharks.

and under magnification (right)
The electric field causes discomfort to a shark and this increases
the closer it gets to the electric field, until it becomes intolerable.
The electrical field transmitted by Ocean Guardian devices has no
known long term effect on sharks. It also has no effect on other
marine creatures.
IMPORTANT: Ocean Guardian devices do NOT attract sharks.
This is a myth and independent scientific research has shown that
electrical deterrents do not attract sharks. As electrical currents can

only travel very short distances through water, the Ocean Guardian
creates only a very localized electrical field.
Shark electroreceptors can only sense electrical currents at very
short distances, typically less than half a meter. When a shark
approaches an Ocean Guardian, these electroreceptors are over-
sensitized, causing the shark to turn away.
Ocean Guardian eSPEAR Electrical Fields
Ocean Guardian has been scientifically proven and independently
tested to be effective at turning sharks away. The following image
displays the electronic fields surrounding the eSPEAR when active.

capability, please visit our website at www.ocean-

WARNINGS:
·The eSPEAR is a high tension spring loaded device.
Always hold device away from the face and eyes. Never
load or activate while pointing towards your body or near
other persons. Always hold your hands firmly over the
eSPEAR end when activating out of the water to absorb
tension and to avoid damaging your device.
·It is recommended that gloves are worn when activating
and deactivating the Ocean Guardian eSPEAR above and
below water to avoid electric 'shocks'.
·Thoroughly dry the eSPEAR before connecting it to the
charger.
·Ensure the eSPEAR is placed on the charger facing the
correct way.
1. Activate the device safely. See Activate and Deactivate the
eSPEAR for details on how to safely activate and deactivate
the device.
2. Hold your hands firmly over each end of the eSPEAR when
releasing the electronics module and electrode while it is out
of the water. This will absorb tension and avoid damaging
the device.
3. Place the eSPEAR into the top of the charger until the
grooves on the device allow it to rest securely in position.
Ensure the eSPEAR is placed on the CHARGER facing the
correct way, as indicated on the CHARGER. Note: The
device is automatically deactivated while charging.

4. A solid GREEN LED illuminates on the eSPEAR while
charging. A GREEN LED also illuminates on the CHARGER.
5. When the eSPEAR is fully charged the GREEN LED is no
longer illuminated.
6. Remove the eSPEAR from the charger and safely deactivate
the device.
Important Notes:
·Do not store the eSPEAR fully charged. We recommend
storing the device with approximately 50% charge
remaining. If the battery is completely discharged after use,
only charge it for approximately half the recommended
charge time, e.g. 3.5 hours. View the section in this manual
titled Operational LED Status Indications for more details
on battery charge status indications.
·It takes 7 hours to fully charge the eSPEAR from complete
battery discharge.

7 Essential Maintenance and Testing
1. Ocean Guardian devices perform a self-check each time they
are turned on. To confirm the device functions effectively you
can also:
a. Place your hand close to the antenna/electrodes to feel
the electric field pulsing when the device is submerged
under salt water.
b. Purchase an Ocean Guardian Tester Unit to verify
whether the Ocean Guardian is producing an electric
field.
2. Thoroughly rinse the Ocean Guardian eSPEAR in fresh water
after each use.
3. Allow the Ocean Guardian eSPEAR to dry before placing it in
storage. Avoid direct sunlight when drying the unit. Store it in a
cool, dry place away from sunlight, preferably in the case
shipped with the unit.
4. The device should be kept free of dirt and sand at all times.
5. We recommend each Ocean Guardian device is stored with
some charge when stored for long periods of time.
Warnings:
·Thoroughly dry the Ocean Guardian before connecting the
charger. Be especially vigilant when charging the Ocean
Guardian immediately after it has been used in water.
·Under no circumstances should you attempt to repair the
Ocean Guardian as this will void any warranty.
