DUTY CYCLE ADJUSTMENT
Duty cycle adjustment affects the
percentage of time that the backpack is
applying power every cycle. To modify
Duty Cycle, press DUTY CYCLE button,
then use the arrows to increase or
decrease values. Once complete, press
the BACK button to return to the 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%- A duty percentage commonly
used for more robust species with
decreased vertebral count and thicker
scaling. This longer duty cycle will
decrease the battery life but will
generally increase capture efficiency.
FREQUENCY ADJUSTMENT
Frequency adjustment determines the rate
of electrical pulsing. To modify frequency,
press the FREQUENCY button, then use
the arrows to increase and decrease
values. Once complete, press the BACK
button to return to the home screen.
A. 7.5-15 Hertz – Low frequency is
commonly used with Pulsed Direct
Current Waveform to capture catfish
and other electrically sensitive bottom
dwelling fish. Fish are often 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.
