APEX Backpack Electroﬁsher Quick-Start Guide

1. External Components

i. Electrodes – Electrically positive

anode and negative cathode of the

electric system.

a. Anode – Attach metal ring to end

of anode pole with 7/16” wrench.

Attach the anode and control con-

nectors to the appropriate recep-

tacles inside the battery compart-

ment. Align and position anode

pole connector’s internal tab with

notch on Apex anode connector’s

notch to mate into position. A half

turn is all that is needed for attach-

ment once properly aligned.

b. Cathode – Attach the cathode connector to the appropriate

receptacle inside the battery compartment. Align and position

cathode connector’s internal tab with notch on Apex cathode

connector’s notch to mate into position. A half turn is all that is

needed for attachment once properly aligned. An anode pole

can also be used as a cathode to increase control over electric

ﬁeld size and direction. If an anode pole is used, the control con-

nector will not be attached on the cathode pole and the ﬂapper

on the cathode pole will be inactive.

WARNING! LIVE ELECTRICAL EQUIPMENT WHEN

ENERGIZED. DIRECT CONTACT WITH EQUIPMENT MAY

CAUSE ELECTRIC SHOCK OR BURN. Appropriate personal

protective equipment is required as all times. Using this equipment

in a manner not advised in the instruction manual, quick start guide,

tutorial video(s) or otherwise could result in injury, death, or damage

to the unit. Users should notify bystanders of the equipment’s use

and function before and during operation. If conditions become

unsafe, cease using the equipment immediately.

Before electroﬁshing, it is strongly advised to have and wear non-

breathable chest waders, electrically rated lineman gloves, and

proper footwear.

ii. Battery – Supplies power to the electroﬁsher

a. Lead Acid – Attach the red and

black connectors from the back-

pack to the red and black connec-

tors on the battery.

b. Lithium – Attach the lithium bat-

tery’s multicolored 6 pin adapter to

the battery then attach the red and

black connectors from the back-

pack to the red and black connec-

tors on the adapter.

c. Strap – Properly attach and tighten

the battery strap to secure the bat-

tery in place during use.

d. Low Battery – The APEX will display a low battery warning when

the battery voltage is below 21.0 volts and electrical output will

cease when the input battery voltage is below 20.0 volts.

iii. Battery compartment lid – Covers and protects battery and con-

nectors.

a. Strain relief - Properly align the strain relief devices on the anode

and cathode cords with the battery compartment lid openings to

prevent strain on connectors.

b. Latches – To loosen the three latches, ﬂip open latches and twist.

To tighten the three latches, twist and ﬂip closed.

c. Safety magnet – A safety magnet is

attached to the inside of the battery

compartment lid. The backpack will

not turn on if this magnet and bat-

ter cover are not properly aligned

and in place.

2. Powering up and down

i. Power button – Red button on top

of backpack with yellow protective

shroud.

a. Double Check – Ensure that battery

and electrodes are properly con-

View of multi-colored lithium

nected, battery compartment lid is properly aligned and in place,

that backpack is upright, immersion sensor is dry and not im-

mersed, ﬂapper switch on anode pole is not pressed, and no one

is in contact with electrodes prior to turning on the backpack.

b. Turn on - Twist and lift the red button to activate the backpack. A

short tone will emit from the backpack then the red light will acti-

vate for duration of the startup time (about 15-20 seconds).

c. Turn off – Push down on the red button.

3. Electrical Settings

i. Waveform – Determines the shape of

the electrical output. Press WAVE-

FORM button and select a waveform.

Press BACK button to return to home

screen. Press FAVORITES button to

store and recall settings. Once com-

plete, press BACK button to return to

home screen.

a. Direct Current (DC) – Continuous,

uninterrupted current, ﬂows from

backpack between anode and cathode. This method is favored

for use with endangered and threatened species because it min-

imizes the incidence of potential injury. However, capture efﬁ-

ciency is low and battery usage is high.

b. Pulsed Direct Current (PDC) – Current is pulsed at a given fre-

quency and duty cycle. This is the most commonly used elec-

troﬁshing waveform because of its balance of minimizing inci-

dence of injury to ﬁsh while increasing capture efﬁciency and

lengthening the use of the battery.

c. Burst of Pulses – Current is pulsed in packets of bursts with

deﬁned gaps of electrical output between bursts. This wave-

form is commonly used with Dual Output mode activated while

catching ﬁsh in heavy cover or removing juvenile lamprey from

sediments.

ii. Frequency – Determines the rate of electrical pulsing. To modify

frequency, press FREQUENCY button, then use arrows to increase

and decrease values. Once complete, press BACK button to return

to home screen.

Screenshot: Waveform types

APEX BACKPACK ELECTROFISHER

a. 7.5 – 15 Hertz – Low frequency is

commonly used with Pulsed Direct

Current Waveform to capture cat-

ﬁsh and other electrically sensitive

bottom dwelling ﬁsh. Fish are of-

ten active, requiring active netting.

b. 30 Hertz – Moderate frequency is

commonly used for more fragile

species with increased vertebral

count and minimized scales.

c. 60 hertz – Higher frequency is

commonly used for more robust

species with decreased vertebral

count and thicker scaling.

iii. Duty Cycle – Determines the percent-

age of time that the backpack is ap-

plying power every cycle. To modify

Duty Cycle, press DUTY CYCLE but-

ton, then use arrows to increase and decrease values. Once com-

plete, press BACK button to return to home screen.

a. 12-15% - A minimal duty percentage that maintains very short

widths for each electrical pulse. Similar to low frequency, this is

commonly used for more fragile species with increased vertebral

count and minimized scales. It also helps conserve battery life.

b. 20-40% (~30%) – A duty percentage commonly used for more

robust species with decreased vertebral count and thicker scal-

ing. This longer duty cycle will decrease the battery life but will

generally increase capture efﬁciency.

iv. Voltage – Determines the amplitude

of the electrical potential. The voltage

should be set according to environ-

mental conditions, especially ambient

water conductivity. To modify voltage,

press VOLTAGE button, then use ar-

rows to increase and decrease values.

Once complete, press BACK button to

return to home screen.

a. 500 – 1,200 Volts – High voltage is used in very low ambient con-

ductivity water. Additionally, higher voltages are often useful in

deep and wide pools. Battery life is signiﬁcantly reduced when

using high voltage.

b. 150 – 500 Volts – Moderate voltage is typically used in moderate

ambient conductivity waters.

c. 50 – 150 Volts – Low voltage is typically used in high conductivity

water. Additionally, lower voltage is often useful in shallower pools.

4. Favorites

i. Saving Electrical Inputs – To save an

electrical input to the Favorites sec-

tion, press the WAVEFORM button on

the home screen, then press FAVOR-

ITES. Finally, press the + button to

save the active input settings.

ii. Recalling Electrical Inputs - To activate

an electrical input previously saved

in the Favorites section, press the

WAVEFORM button on the home screen, then press FAVORITES.

Finally, press the button associated with the previously saved input

settings of choice to active them.

5. Effort

i. Timer/Alarm

a. Timer – The timer counts the number of seconds the ﬂapper

was activated since the timer was last reset. To reset the tim-

er, Press the TIMER button, then press RESET. Once complete,

press BACK button to return to home screen.

b. Alarm – An alarm can be set at 60 second intervals to inform

the user that a deﬁned amount of effort has elapsed. A re-

minder alarm will subsequently activate every 60 seconds of

effort beyond the alarm. Therefore, it can be helpful to set the

alarm for 60 seconds less than the intended effort as a meth-

od of warning the user of the upcoming end of effort. To set

the Alarm, press the TIMER button, then press ALARM and use

arrows to increase and decrease the number of seconds. Once

complete, press BACK button to return to home screen. A ton-

al alarm will activate once the noted amount of electroﬁshing

effort elapses. A reminder alarm will continue to occur every

60 seconds after the alarm is triggered until the timer is reset.

6. In Field Help

i. Light Bulbs – Light bulb icons can be accessed on the backpack for

further information on particular topics.

ii. Diagnostic Screen – A diagnostic screen can be found in the menu

that displays a multitude of input and output parameters along with

system information.

7. Menu

i. Quick Setup – Quick Setup will de-

termine a conservative voltage by

sampling the resistance of the elec-

tric circuit when the electrodes are

placed in the water. Therefore, it is

imperative that electrodes be sub-

merged in the water in a typical

position for your given sampling site.

Once standing in a typical electro-

ﬁshing position, press and release

the pole switch. Observe the recommended voltage. Pressing and

releasing the pole switch will continue to offer voltage suggestions.

Sampling multiple times will give a sense of consistency of read-

ings. Note that a change in electrode placement will impact circuit

resistance, and will therefore impact recommended voltage. Wave-

form will always be set to Pulsed Direct Current, Frequency will

always be set to 30 Hertz, and Duty Cycle will always be set to 12%.

After running quick setup, the user may need to slightly increase

the voltage to increase capture efﬁciency.

ii. Electrode Out of Water Alarm – A safety mechanism that stops

electrical output when an electrode is removed from the water or

the circuit is broken.

a. Activated – If very high resistance is encountered because a con-

nector is loose, an aluminum anode pole that is corroded, or an

electrode is removed from the water, the backpack will stop the

output of electrical current. To reactivate, tighten connector or

place electrode back in water and press the anode pole ﬂapper

once again.

b. Deactivated – While continuously holding down the anode pole

ﬂapper switch, the backpack will immediately deliver electrical

current once the electrical circuit is completed. This is common-

ly used in shallow rifﬂes areas where the circuit is frequently bro-

ken when bouncing the electrode from small pool to small pool.

iii. Power Limit – Allows the user to decrease to output power capaci-

ty of the backpack.

a. 400 Watts – The backpack will automatically default to 400

Watts upon startup. This is the maximum output the backpack

can sustain and is the setting to continue using to realize the full

capabilities of the backpack.

b. <400 Watts – Users can limit the output of the APEX backpack

to standardize use with alternative backpack electroﬁsher manu-

facturers. This restriction ensures that capture efﬁciency is main-

tained between equipment.

iv. Power Limit Response – Determines the response of the backpack

when the Power Limit is reached.

a. Alarm – Output power will cease and an alarm with indicate that

the power limit was reached.

b. Reduced Voltage and/or duty cycle – Output power will contin-

ue and the backpack will automatically reduce the voltage to

prevent the power limit from being exceeded. This is most often

used when operating at the extremes of the backpack’s environ-

mental capabilities (i.e. unusual ambient water conductivities).

v. Dual Channels – Allows the user to deﬁne and activate two differ-

ent electrical outputs by releasing and pressing the anode pole

ﬂapper in less than one second.

a. Activated – A single electrical output is set on the main screen.

b. Deactivated – Two electrical outputs, a primary and a second-

ary, are set on the main screen. This is commonly used when a

sensitive setting is used in the primary output slot and a more

aggressive output is used in the secondary to allow ﬁsh to es-

cape heavy cover then be properly incapacitated. The primary
