Setting the Frequency
The FLX-30 Broad Band sonar has the ability to operate on a
frequency tailored to your specific fishing situation. The “F” on the
Mode Control stands for “frequency.” Set the Mode to F and then
push in on the Gain Control to change the frequency.
The standard rule with frequency is this: the lower the frequency, the
wider the beam angle, and the higher the frequency the narrower the
beam angle. If you feel the display has too much clutter, interference,
large signal sizes, or you start seeing strange things floating in the water
like freshwater shrimp, zoo plankton or even thermal stratification in
the water column, cycle your unit through the seven frequency options
to see if you can improve the view. You will see the current frequency
selected located in the 11 o’clock position on the main dial.
Expect to adjust the Gain level to maximize the performance of each
frequency. With a standard 200 kHz system, anglers should keep the
gain as low as possible at all times, but with the FLX-30, a higher gain
setting is required the higher the frequency selected.
Auto Range Operation
Auto Range automatically selects the proper range for you.
However, it is not infallible. It is possible to confuse the “Auto
Range” operation when fishing over very soft lake bottoms or
during conditions of thick ice. The software cannot find a bottom
point in the return signal strong enough to trigger a lock. For this
reason, there can be an eight second delay beginning when you put
the transducer in the water before the unit attempts to lock. The
display will show SEARCHING as it processes the signal to best
determine the true bottom point.
When soft bottom conditions exist, you may need to turn up the
gain initially to help the program find bottom. Then turn the gain
back down when fishing. If you find the Auto setting cannot lock on
bottom, the display will request that you switch to a manual range
group. Turn the Range Control to the right until you see the bottom
appear. Also, switch to High Power.
NOTE: There is nothing wrong with your Vexilar unit if it cannot
lock on a range automatically. This is a very unique fishing scenario.
Try switching to 200kHz, a manual range or moving to a new
location. Also note that the digital depth display may be unreliable
in this type of condition.
