setup
The
Strike 220s
fishfinder is able to display boat
speed, water temperature, and water depth. This
menu enables you to customise the display of
speed and temperature and to change the
calibration setting of these features.
Temperature units Temperature can be
displayed in either °F or °C.
Temperature calibration If the displayed
temperature is known to be wrong then it can
be adjusted using this function. The
calibration value is saved in memor y
automatically.
Speed units of measure Speed can be
displayed in either knots (KTS) miles per hour
(MPH) or kilometres per hour (KPH).
Speed calibration If the displayed speed is
known to be wrong then it can be adjusted
using this function. The calibration value is
saved in memory automatically.
Reset log The distance log can be reset by
changing this option from ‘NO’ to ‘YES’. If the
selection is YES, the log will be reset when
you exit this menu.

Speed Comparison Method
Use the following sequence to adjust the speed
displayed to match that of another craft or the
speed displayed on a GPS receiver. Enter the
Speed calibration mode as described on page
16 of the manual, SETUP 2 Menu / SPD CAL.
To increase reading, press the
key.
To decrease reading, press the
key.
Adjust to desired speed, press the power
key to store in memory and exit.
Log Calibration Method
Go to the SETUP 2 Menu / RESET LOG and
reset the log to zero. Travel a known distance
between two points. If there is any tidal current,
you should travel the course in both directions
and twice the known distance. Avoid situations
where the current is flowing at right angles to the
course. If this cannot be avoided, make sure that
the boat speed is at least ten times the speed of
the current.
You may calculate a correction factor as follows:
For example, if you have travelled over a known
distance of 1 mile but your log reading is 0.80,
the correction factor is 1.25.
Therefore, your correct boat speed will be the
indicated speed multiplied by 1.25. For example,
a current boat speed of 4.00 KTS should be
increased to 5.0 KTS (4.0 x 1.25). Go to the
SETUP 2 Menu / SPD CAL and adjust to the
correct speed.
