PTIONS

Auto Color Gain—controls what colors are applied to the objects 

on the screen. Color DCG is based on depth and makes it easier to 

spot subtle changes in bottom conditions or fish sizes. DynaColor 

(default) represents the latest in sonar data presentation and is 

recommended for all applications. The presentation is based on 

bottom strength. It makes the bottom and the fish easier to see and 

requires fewer adjustments.
Automatic Gain Level—controls the aggressiveness of the Auto 

Gain. The higher the setting, the greater the number of targets 

appear on the screen. The lower the setting, the less clutter on the 

screen. The settings are Low, Medium (default), and High.

Automatic Scroll Speed Limit—automatically adjusts the Scroll 

rate (see 

page 74

maximum cruising speed produces a 100% scroll rate when you 

reach that speed. One half of that speed produces a 50% scroll rate, 

and so on. The default is 30.0 kt.
Transducer Type—allows you to specify what type of transducer 

you are using.
Calibrate Water Speed—this appears only if you are using a 

speed-capable transducer/sensor. Calibration is required to ensure 

that the Water Speed shown on your unit is accurate. The unit 

automatically uses GPS ground speed for comparison on the 

calibration. If a GPS ground speed is not available, use either your 

boat’s speedometer reading (not always accurate) or a stopwatch 

to determine your speed over a certain distance (distance / time = 

speed). It is recommended that the calibration take place in water 

having little or no current.
