The Humminbird FishFinder can display a variety of useful information about the area 

under and adjacent to your boat, including the following items:

Depth - 

water depth; can be set to alarm when the

water becomes too shallow.

Temperature -

water surface temperature.

Second Sonar Return - 

when the sonar signal

bounces between the bottom and the surface of
the water and back again. Use the appearance of
the second return to determine bottom hardness.
Hard bottoms will show a strong second return,
while soft bottoms will show a very weak one or
none at all. 

Speed -

if a Temp/Speed accessory is attached, the

FishFinder can display the speed of the boat, and can

keep a Triplog of nautical or statute miles traveled.

Battery Voltage - 

the voltage of the boat’s battery;

can be set to alarm if the voltage falls below a
certain point.

RTS® (Real Time Sonar) Window

Soft Bottom

Thermoclines -

layers of water with different

temperatures that appear at different depths and
different times of the year.  A thermocline typically
appears as a continuous band of many gray levels
moving across the display at the same depth. 

Structure -

where fish may be hiding. 

Fish -

the FishFinder displays fish as arches and/or

fish icons, and can be set to alarm when a fish of a
certain size is detected. When a target is detected, a
Fish ID+

TM

symbol appears on the display with the

depth displayed above it. The size of the symbol
indicates the intensity of the sonar return. The unit
will clearly show schools of Bait Fish as "clouds" of
different shapes and sizes, depending on the
number of fish and boat speed.

Bait Ball

Hard Bottom

Rocky Bottom

Timer -

Elapsed time with Temp/Speed Accessory.

Distance -

Distance traveled with Temp/Speed

Accessory.

Average Speed -

Average speed reading with

Temp/Speed Accessory.
