MAINTENANCE
Your Pinger is constructed of corrosion resistant materials and was
designed to be maintenance free. However, as with most diving equip-
ment, it is recommended that it be rinsed in fresh water after use
and stored in a cool, dry place.
Protect the pinger transducer. Do not toss the pinger into a box
with other equipment. The transducer should be keep clean (soap
and water) and protected from damage.
If the unit is disassembled, the o-ring can be lubricated with a
silicon based lubricant.
When storing the pinger for more than a few weeks, the batteries
should be removed from the pinger.
LIMITED WARRANTY
Your Pinger underwent constant inspection during assembly to in-
sure many years of trouble free performance. The pinger is war-
ranted for TWO FULL YEARS from the date of purchase. During
this period your pinger will be repaired free of charge should a failure
occur due to materials or workmanship under normal use.
The warranty does not cover damage due to dropping or general
misuse. The warranty covers JW Fishers equipment only. JW Fish-
ers will not be liable outside of the remedies stated above.

CAUTIONS:
Do not allow the Pinger to be exposed to excessive heat by leav-
ing it in direct sunlight or inside of a closed vehicle on a hot day.
Excessive heat can damage the electronics and/or destroy the wa-
terproof seals.
The Pingers signal originates from the transducer (black end) at
the end of the pinger. The transducer should be kept clean (soap and
water) and protected from damage. The two screw-heads, visible at
the end of the transducer, should be keep free of debris. When water
touches the two screw-heads, the pinger turns on (if the pinger is in
water turn-on mode).
Always test pingers and pinger receivers on land or in shallow
water before deploying in open water. Pingers do not broadcast sig-
nals very far through the air; however, they can be detected 5 to 10
feet away by a pinger receiver (a “clicking” noise can also be heard
from the transducer.)
Before deploying a pinger, write down the pinger frequency for fu-
ture reference (when you want to find it, you need to know the fre-
quency.)
Before deploying a pinger in the water, be sure the electronics and
seals are pushed into the pinger housing. To do this, push the end of
the black transducer in the direction of the housing. Screw the cap
snug, but do not overtighten.
Before swimming in the direction of a received pinger signal, al-
ways double-check other directions to insure that this direction is
producing the strongest signal, and that it’s not a reflected signal
(see pages 5 and 6 of this manual.)
When storing the pinger for more than a few weeks, the batteries
should be removed from the pinger.

INTRODUCTION
Pingers are devices that generate acoustic signals underwater.
They are used to mark an underwater site or piece of equipment so
a returning diver, using a pinger receiver, can locate the exact spot.
DIVER WITH PINGER RE-
CEIVER PREPARING TO DIVE
TO LOCATE PINGER IN WATER.
JW Fishers family of commercial grade pingers include both the
Single Frequency Pinger (SFP-1) and the Multifrequency Pinger
(MFP-1). The SFP-1 is available in several frequencies one of
which is specified at time of order (22, 32, 40, or 50kHz). The MFP-
1 has user selectable frequencies from 20 to 50 kHz in 500 Hz
increments. The operator selects one of 60 different frequencies
before deploying the pinger. Many pingers can be deployed in the
same general area, each transmitting at a different frequency. This
enables a diver with a pinger receiver to pinpoint the exact location
of each pinger without interference from the other pingers.
THE SFP-1 AND MFP-1 ARE
THE SAME SIZE.
Pingers are available with different transmit frequencies so sev-
eral can be deployed in the same general area without interference
from each other. The diver adjusts his pinger receiver to the fre-
quency of the desired pinger and the receiver leads him to it.
ELECTRONICS BOARD REMOVAL
The electronics board is bolted to the transducer. The transducer is
held in place by the Retaining Cap. Open the pinger housing by first
turning the Retaining Cap counterclockwise (it should not be tight.)
When the Retaining Cap is loose, pull out on the Retaining Cap and
transducer which will remove the transducer and electronics board
from the housing.
Note that the transducer has an o-ring (below the Retaining Cap)
that seals the pinger from water. Be careful to keep this o-ring clean
and free of damage. The o-ring can be lubricated with a silicon based
lubricant.
When reinstalling the electronics be sure the o-ring is pushed into
the pinger housing. To do this, push the end of the black transducer
in the direction of the housing. Screw the Retaining Cap snug, but
do not overtighten.
BATTERY INSTALLATION
The SFP-1 and the MFP-1 use two 9 volt Alkaline or Lithium bat-
teries. The “Extended Operations Option” package uses six batter-
ies.
To install batteries:
1) Remove the electronics board (see above.)
2) The batteries are mounted directly on the electronics board;
one battery on each side of the board ( the “Extended Operations
Option” package uses three batteries on each side.) The batteries
are installed “terminal end” in first (observe correct polarity.)
3) After the battery terminals are pushed in-place, push down on
the other end of the battery while pushing away the black tubing to
make room for the battery. It is intended to be a tight fit. The black
tubing holds the battery in-place so it cannot be jarred loose.
The black tubing is not used for the bottom battery on the back
side of the board. This battery is held in-place by the sponge rub-
ber in the bottom of the housing.

Fishers pingers have several operator adjustable features includ-
ing pulse repetition rate, the length of each pulse, and the output
power. The length of each pulse and output power adjustments allow
the operator to adjust the distance the pingers can be detected. With
the MFP-1 the transmission frequency can be selected by the op-
erator before deployment. These features make the SFP-1 and the
MFP-1 extremely versatile and the first choice for almost any appli-
cation.
Power for the pingers is supplied by two standard alkaline 9 volt
batteries which last from a few days to many months, depending on
output power and pulse selection. For long durations lithium batter-
ies can be used. A longer housing, as shown above, is also avail-
able which holds six batteries to give 3 times the normal operating
time. The pinger is automatically activated when put in the water or
manually activated with a switch.
BOTH THE SFP-1 AND MFP-1
ARE AVAILABLE WITH A
LONGER HOUSING. THE
LONGER HOUSING HOLDS
MORE BATTERIES FOR EX-
TENDED OPERATIONS.
DISTANCE
How far a signal can be detected from a pinger varies greatly on
water conditions. The rougher the water, the more noise there is in
the water. Noise in the water makes it difficult for a receiver to pick
out the signal from the background noise. Noise in the water also
attenuates the pinger’s signal; which shortens the distance the sig-
nal will travel. On a quiet deep water lake, a range of up to 1,500
meters would not be unusual; in shallow rough water, 150 meters
may be hard to do.
Thermoclines (layers of water at different temperatures) also inter-
fere with sound traveling through the water. When sound hits a ther-
mocline, some of the signal bounces off the thermocline, leaving a
reduced signal passing through the thermocline and on to the re-
ceiver.
Pinger frequency also effects the maximum distance a pinger sig-
nal can travel. The lower the frequency, the farther sound will travel
in the water. The signal from a 20 kHz pinger will travel further than
a signal from a 50 kHz pinger.
12
BATTERIES
JW Fishers pingers are powered by standard 9 volt batteries (square
rectangular shape). Two types of batteries are recommended for use
in pingers: Alkaline or Lithium. Alkaline batteries are available ev-
erywhere. Look for the word “Alkaline” printed on the battery. There
are cheaper batteries available that are not Alkaline. Lithium batter-
ies are harder to find and are expensive; however, they last twice as
long as Alkaline.
The standard pinger uses two 9 volt batteries. The “Extended Op-
erations Option” package uses six batteries which operates 3 times
longer than the standard pinger. The batteries are all in parallel so
you can use any number of batteries and the unit will operate. The
number of batteries that are used determine how long the pinger will
operate; not how much output power the pinger will produce.
BATTERY LIFE
Battery life is dependent on the settings you chose for the pinger.
If you need the longest range possible then select the maximum
Power Output and the longest Pulse Length; however, this results in
the shortest battery life.

THEORY OF OPERATION
When the pinger is turned on (manually, or automatically when the
pinger is put in the water) a continuous series of acoustic pulses
(sound waves) are emitted from the transducer (black end) of the
pinger. The pulses are of very short duration. The pulse length is
measured in milliseconds (ms), and travel out from the transducer
in all directions.

4 ms (pulse length)
1 sec
(one sec between pulses)
Pulse
amplitude
The operator has complete control of the output signal by “push on”
jumpers on the electronics board. These jumpers are set prior to
deployment of the pinger.
1) The pulse length (4 ms shown above) is operator adjustable
from 1 to 5 ms (may vary with model). The longer the pulse, the
further the signal will travel in the water; but the longer pulse
consumes more power and shortens battery life.
2) The repetition rate (sec between pulses) is also operator ad-
justable from .5 sec between pulses to 2 sec between pulses (1
sec between pulses shown above). A shorter rep rate does not
increase range; but it is easier to locate a pinger operating at .5
sec between pulses than one operating at two seconds between
pulses. A pinger operating at .5 sec consumes twice the battery
power of a pinger operating at a 1 sec rep rate.
3) Power output (pulse amplitude) is also operator adjustable
from .1 to 8 watts (may vary with model). The higher the output
power the farther the signal will travel through the water. Dou-
bling the output power increases the distance; but does not double
the distance. Doubling the output power reduces battery life in
half.

4) Frequency of the pinger (the frequency of the individual pulses
within the 4 ms time frame shown above) is factory set for the
Single Frequency Pinger (SFP-1) at 22, 32, 40, or 50kHz at time
of order. The Multifrequency Pinger (MFP-1) is operator adjust-
able from 20 to 50kHz. Generally speaking, the lower the fre-
quency of the pinger, the further the signal will travel.
5) Power activation of the pinger is operator selectable. “Off”
position does not allow power to the unit. “On” position forces
the unit on. “Water” position turns the unit on when the pinger
enters the water (when water touches the metal contacts on top
of the transducer).
If it is going to be a long term deployment the “On” position is
recommended (Metal Contacts could possibly become corroded
over a long term).
The signal is radiated out from the transducer end of the pinger. A
floatation collar (included) is installed on the transducer end of the
pinger anytime the pinger is tied to a target on the ocean floor. The
floatation collar keeps the transducer end pointed up so that the
radiated signal is upward as well as out to the sides.
The floatation collar is not used when the pinger is tied off to a
target on the surface of the water. In this situation the transducer
would be pointing down (it’s natural orientation).

To mark an anchor line for returning divers, use the same setup
as above and tie the pinger cord to the anchor line 6-10 foot up
from the anchor (before deploying the anchor.)
To mark a boat or target on the surface, remove the flotation
collar and tie the pinger cord to the boat (transducer will be
pointed down.)
PINGER DEPLOYMENT
Before deploying the pinger, write down the pinger frequency for
future reference (when you want to find it, you need to know the
frequency.)
The transmitted signal is stronger from the top and sides of the
pinger transducer than it is from the bottom. When marking a target
on the ocean bottom, install the flotation collar under the Retaining
Cap (to keep the transducer pointed up) and tie a cord from the
bottom of the pinger to the target.

OPERATION
Pinger operation is simple and straight forward.
1) Remove the electronics board (see page 11).
2) Install “push on” jumpers (see page 6 or 7) for:
• Power Output ............................................................ 2 watt
• Rep Rate .................................................................. 1 Sec
• Pulse Length ............................................................. 3 ms
• Power Activation............................................................ On
Always test pingers and pinger receivers on land or in shallow
water before deploying in open water. Pingers do not transmit sig-
nals very far through the air; however, they can be detected 5 to 10
feet away by a pinger receiver.
If you are operating the pinger in air, a “clicking sound” can be
heard from the transducer each time a “ping” occurs. You may not be
able to hear it if you have the jumpers set for a low power output.
Before deploying a pinger in the water be sure the electronics and
seals are pushed into the pinger housing. To do this, push the end of
the black transducer in the direction of the housing. Screw the Re-
taining Cap snug, but do not overtighten.
Be sure to use fresh batteries each time the pinger is used. The
cost of a fresh set of batteries is small compared to the loss of a
“dead” pinger, or a delay in the project while you relocate the target.
