Vexilar 107 Pro - Manual (Page 2)

GENERAL DESCRIPTION
The 107 Pro incorporates an extremely high quality
sonar circuit with an easy to understand interface. The unit
is designed to be effective and easy to use. All the main
functions are only one button away. Range and Gain con-
trols are selectable as fully automatic or easily controlled
manual modes independent of each other. Internal battery
backup saves all selections upon power off.
The output frequency of 107 KHz is much lower than
most depthfinders of today. This is designed to give more
output power and a greater area of coverage. The 107 Pro
can truly "arc" fish and does not need to use artificial fish
symbols.
The 107 Pro incorporates Clean Line circuitry that can
"clean out" the harder targets. The bottom, rocks, and dense
weeds are made transparent so fish are more visible near
them. On a hard rock or gravel bottom, fish on the edge of
the cone angle can actually be seen within the bottom sig-
nal. And with a 38˚ cone angle, you can cover allot of area.
There are three Zoom Zones which let you hone in on
the area you want to see best. You can zoom just the top
half, middle, or bottom half of the display. These features
are easily activated by a single press of a button. Switching
back and fourth is quick and easy.
Speed and Temperature sensors are included. Two dis-
