Basic Concept
Most sonar systems sold today use a frequency of 200 kHz. This has
been a well-accepted frequency by most anglers and boaters for over 40
years. While not perfect, the 200 kHz is well suited to getting sonar depth
readings down to 300 feet, even though most are actually used in waters
under 40 feet.
Sonar designers fully understand the limitations of a single frequency
system, but the option for offering several frequencies in a single system
was so expensive that it was not a commercially viable option, until the
development of the Broad Band transducer. For the first time, a composite
crystal could be made from an array of small crystals interconnected into
one compact housing. The result is to deliver a wide spectrum of sonar
frequencies in one transducer.
No one frequency is "perfect" for all situations, but the seven frequencies
found in the FLX-30 give some great options for serious anglers looking
for the best possible performance from a single sonar device. Now, when
fishing 300 feet of water, the angler can use a powerful 160 kHz signal,
but later adjust to a higher 300 kHz transmit frequency when fishing in
only 5 feet of water. So you now have the option to adjust frequencies
and power levels to give you the finest sonar response possible for a
given fishing situation.

START Mode
Before turning on the FLX-30 , adjust the Mode Control to the
"S" or START position. This will give you easy access to begin the
day using popular factory settings. You will learn it is possible to
customize the performance of the unit, in many ways. This mode
setting makes it easy to start fishing a new lake, or if you wish to
remove past settings and start over. The "S" mode factory settings
will perform well in nearly all fishing situations.

Manual Depth Range
With the Range Control set to Auto, when powering the unit on
you may see the word "Searching" for up to 8 seconds. The system
is looking for the bottom to establish the best depth range and
Interference Rejection setting for you. Once the depth is found the
digital depth reading and the proper range setting will be displayed
at the bottom of the display.

Mode and Gain Controls
The Mode and Gain controls work in conjunction with each other. You first select the Mode,
then push in on the Gain Control to cycle through the Mode's options. The display will show you
the current setting.
Mode Settings and Options
Zoom (Z): This mode allows you to cycle the Auto Zoom setting between the available zoom
ranges; 6', 12',18' and OFF.
Frequency (F): This mode allows you to control the FLX-30's Broad Band setting. Cycle
through these frequencies: 160, 180, 200, 225, 250, 275 & 300 kHz (see next page)
Power (P): This mode allows you to choose the output power mode.
Choose from: Low, Medium and High
Range (R): Auto Range: 10, 15, 20, 25, 30, 40, 50, 60, 80, 100, 120, 160, 200, 240 and 300 feet
Shallow Range Group: 10, 15, 20, 30 and 40 feet
Middle Range Group: 50, 75, 100, 125 and 150 feet
Deep Range Group: 175, 200, 225, 250 and 300 feet
