Zoom; Fish Id - Eagle SUPRAPRO I.D. Installation And Operation Instructions Manual

ZOOM

The zoom feature enlarges all echoes on the screen. If the unit is in the
automatic mode, it tracks the bottom signal, always keeping it near the
bottom of the screen. This lets you see small detail, at the same time
enlarging all echoes that appear on the screen.
Remember, the unit doesn't track the bottom
in the manual mode.
To zoom the display, first press the MENU key
until the RANGE/ZOOM menu appears. Now
press the down arrow key. This switches the
unit into the zoom mode. When the unit is in
automatic and it's switched into the zoom
mode, the range changes to keep the bottom
signal on the display at all times. This won't
happen if the SupraPro I.D. is in the manual
mode.
To turn the zoom feature off, press the menu key until the RANGE/ZOOM
menu appears. Now press the up arrow key. This switches the unit into the
range mode, which turns the zoom feature off.
FISH ID FEATURE
The Fish ID feature identifies targets that meet certain conditions as fish.
The micro-computer analyzes all echoes and eliminates surface clutter,
thermoclines, and other undesirable signals. In most instances, remaining
targets are fish. The Fish ID feature displays symbols on the screen in
place of the actual fish echoes. There are four symbol sizes: tiny, small,
medium, and large. These show the relative size between targets. In other
words, it displays a small fish symbol when it thinks a target is a small fish,
a medium fish symbol on a larger target, etc.
The micro-computer is sophisticated, but it can be fooled. It can't distin-
guish between fish and other suspended objects such as turtles, sub-
merged floats, air bubbles, etc. Individual tree limbs extending outwards
from a group of limbs are the hardest objects for the Fish ID feature to
distinguish from fish. You may see Fish ID symbols on the screen when,
in fact, there are no fish. Practice with the unit when the Fish ID feature is
on and off to become more familiar with Fish ID.
When the SupraPro I.D. is first turned on, the Fish ID feature is automati-
cally turned on, also. To turn this feature off, press the menu key until the
