Hybrid Sonar Technology Enhances
Bass Fishing
By Frank Flack

There is no doubt if you want to catch more bass; you need to
position your boat where the fish will be holding. It is the
dirty little secret many super-star tournament pros fail to
mention when they are on stage and talk about their victories.
If you read between the lines, it is clear the winner put their
boat in the right spot at the right time and kept it there so
they could win. We agree that the secret lure was a factor, so
did the Brand X rod, but let’s be honest, it is about holding
the boat near or over the fish better than the other guys to
win.
For over 20 years, the use of LCD Sonar has been the stable
of most bass fishing rigs. The problem with all LCD sonar’s
today is that this type of pure-digital technology only shows a
digitally processed history of what you have passed over with
your boat. Bass anglers need to know current information about
where the boat is holding at any given time. It might sound
strange, but in some regions of the country, bass anglers never
even use their sonar systems for bass fishing. Most feel using
sonar is no real advantage to them since they simply cast or
flip the bank anyway. Most LCD displays seldom work in waters
less than five feet, so why even turn the darn thing on? When
the idea of heading way from the bank to fish a creek channel or
to fish deep structure, make many anglers nervous and they run
back to the docks.
The goal of every bass angler is to improve their skills with
every tournament and look for tricks and secrets to enhance
their fishing success. Strange enough, but more priority is put
on the type of line or lures in use than to address the ultimate
fish catching technique — better boat control.

Bass fishermen need an easy way to know exactly where the tip
of a brush pile is located or the exact inside turn of a creek
channel. The classic liquid crystal sonar technology, whether in
black and white or the new TFT color displays, only shows the
recent history of lake bottom that your boat has passed over.
Granted, it is a big help to mount your sonar transducer on your
electric trolling motor, but again, if you hold over a spot, the
signals are distorted. If a fish or tree limb is below you, you
see a long cloud shape on the screen. No classic fish hooks are
displayed if you are holding on a spot while fishing. Signals
are processed digitally to filter out small objects in the water
like shad, shiners and even weeds to give the unit a nice clean
TV-like display.
Needless to say, getting your sonar to reveal an uncensored
sonar and a true real time response for a display is the key to
good boat control. This is what the pros are not telling you.
They may be fishing a bottom transition of mud to gravel, a
change from coontail weeds to milfoil or simply looking for
depressions in thick milfoil patches for flipping.
The ONLY sonar technology that delivers this type of
performance is a sonar technology that has been around even
longer than LCD recorders. They are called “flashers” and like
LCD sonar, there are a wide variety of performance features
available.
The clear leader with this type of sonar technology is the
Vexilar Marine Electronics company of Minneapolis. They were the
first to develop a hybrid flasher sonar that takes advantage of
both digital and analog technology for the first super bright,
three-color LED display. This gives you a way to see what is
below your boat in real time and in an unfiltered way. You will
be able to see the tiniest of objects in the water and can
decide if the displayed signal is telling you something vital to
your fishing success.
Many older anglers are familiar with old-style flashers from
yesteryear and have used them with great success, but many have
simply forgotten their advantages. A Vexilar Flasher of today
has come a long way and can easily let you shoot a signal
through the thickest of milfoil to find true bottom, a big
advantage for Texas bass anglers for sure.
A Vexilar Flasher shows the slightest change in bottom
content or weeds instantly. You are able to fish individual
limbs of a tree in a brush pile and lets not forget that this
flasher can also read bottom in 6 inches of water.
The new Vexilar FL-10 and FL-12 Flasher sonar systems use a
unique flat panel display that is visible on a sunny day and
will fit most bass boats on the market. Many bass anglers love
Vexilar Flashers for their real-time signal response at high
speeds because it is impossible to outrun the sonar signal if
the transducer is installed properly.
Boat control is serious business to serious bass anglers. If
you take advantage of what a flasher sonar can do you will be
amazed how quickly you will be able to pinpoint fish holding
structure. Is catching fish faster and easier with better boat
control? One hundred percent yes is the answer, so maybe it is
time to learn how a flasher sonar system can help you catch more
fish this season.
