CONTROL FUNCTIONS
The ProAngler uses a simple 5-button keypad for all user input. When any button is pressed, an
audible "chirp" confirms the control input. In the event that a particular button has no function or is
inappropriate for the situation, an audible "error", or multiple chirps, will be heard.
POWER, powers the ProAngler up for normal operation. When the unit is on,
POWER turns the unit off. POWER can also be used to go directly into
Simulator mode. With the unit powered off, press and hold POWER for several
seconds until a continuous chirp is heard.
When a sonar signal is reflected off the bottom back to the transducer, there is
often enough energy left in the signal to be reflected oft the surface of the water
back to the bottom a second time. Second returns appear as a slightly weaker
bottom representation exactly twice the depth of the primary bottom return. The
second return is most likely to occur in shallow water and in areas of relatively
hard bottom.
The ProAngler uses advanced signal processing to further evaluate any sonar
return between the surface and the bottom. For instance, a small school of bait
fish usually appears as a dense cluster of individual dots. If the return meets certain additional
criteria, a fish symbol will be assigned. There are three different size fish symbols used to indicate
the intensity of the sonar return. While signal intensity is a good indicator of relative fish size,
different species of fish have different sonar characteristics, so it is not always possible to
distinguish fish size between varying species. The signal intensity is "normalized" for depth so
that a small fish close to the boat does not appear as a large fish symbol.
LIGHT controls the unit's 3-position display backlight. With the unit powered on, pressing LIGHT
once will turn the backlight on "high". Pressing LIGHT a second time will turn the backlight on
"low", and pressing a third time will turn the backlight off. The backlight is very effective for low-
light and nighttime operation. When the backlight is on, the ProAngler will consume more power
than with the backlight off. This is important when using the ProAngler in a portable configuration
powered by a separate battery, or when powering the unit from a trolling motor battery.
NOTE: When powering the unit from a battery such as in portable applications, avoiding use of
the backlight prolongs battery life.
The three lower buttons, MENU, UP ARROW, and DOWN ARROW work together to control the
ProAngler menu-controlled user functions.
MENU brings a menu on-screen for adjustment. In normal operation, pressing MENU repeatedly
will cycle through all available menu headings. When the desired menu heading is displayed, the
full menu appears after a short pause. A menu remains on-screen for several seconds allowing
user adjustment by means of the ARROW keys. If no adjustment is made in the allotted time, the
menu disappears. If you need the menu to remain on-screen longer to study the adjustment
