One of the best ways to get fish arches is to expand or “zoom” a
segment of the water. For example, from 30 to 60 feet. The smaller the
segment, the better the screen resolution will be. The easiest way to do
this on the SupraPro I.D. is with the Zoom feature. This feature expands
the echoes, making it easier to see detail. For the best results, turn the
sensitivity up as high as possible without getting too much noise on the
screen. In medium to deep water, this method should work to display
fish arches.
If you see fish signals when the unit is in the manual mode, but don't get
fish symbols when the Fish I.D. feature is on, try increasing the sensitiv-
ity.
SURVEYING A LAKE
The most successful anglers on any body of water are those who fish it
day after day and year after year. Eventually, they learn the hot spots
that produce fish consistently. They discover through experience
where, and at what depth, they can expect to find the fish they want at
any season. And they realize that these productive areas change
throughout the year depending on water level, temperature, food, and
other factors.
With the SupraPro I.D., anyone can eliminate guesswork and concen-
trate on the areas where fish are likely to be. Even if it’s the first time on
the lake!
The most efficient way to become acquainted with a body of water is to
survey it with your SupraPro I.D. Start with a map of the lake, if possible,
and indicate the promising spots in relation to landmarks on shore.
Keep a few marker buoys in the boat, ready to toss overboard. When
the SupraPro I.D. indicates a school of fish, throw the buoy out. With the
school thus marked, you can make your turn and come back to fish in
exactly the right spot. This is essential when you’re far from shore on a
big lake. Unless you mark the school of fish when you’re over it, you
may not be able to find it again.
BAIT FISH
The importance of bait fish to successful fishing can’t be over-empha-
sized. They are the principle food of all game fish in most waters.
Bait fish are the plankton feeding forage fish, such as minnows and
shad. Bait fish can also be the young of game fish, such as crappies,
bluegill, and bass.
