Garmin echoMAP CHIRP 74cv オーナーマニュアル

You are responsible for the safe operation of your boat. Do not 

begin a pattern until you are certain that the water is clear of 

obstacles.

The autopilot can steer the boat in preset patterns for fishing, 

and it can also perform other specialty maneuvers such as U-

turns and Williamson turns.

You can use the u-turn pattern to turn the boat around 180 

degrees and maintain the new heading.

From the autopilot screen, select MENU > Pattern Steering 

> U-Turn.

Select Engage Port or Engage Starboard.

You can use the circles pattern to steer the boat in a continuous 

circle, in a specified direction, and at a specified time interval.

From the autopilot screen, select MENU > Pattern Steering 

> Circles.

If necessary, select Time, and select a time for the autopilot 

to steer one complete circle.

Select Engage Port or Engage Starboard.

You can use the zigzag pattern to steer the boat from port to 

starboard and back, over a specified time and angle, across 

your present heading.

From the autopilot screen, select MENU > Pattern Steering 

> Zigzag.

If necessary, select Amplitude, and select a degree.

If necessary, select Period, and select a length of time.

Select Engage Zigzag.

You can use the Williamson turn pattern to steer the boat 

around with the intent of running alongside the location where 

the Williamson turn pattern was initiated. The Williamson turn 

pattern can be used in man overboard situations.

From the autopilot screen, select MENU > Pattern Steering 

> Williamson Turn.

Select Engage Port or Engage Starboard.

When properly connected to a compatible transducer, your 

chartplotter can be used as a fishfinder. Different sonar views 

can help you view the fish in the area.
The adjustments you can make to each sonar view vary 

depending on the view you are in and the chartplotter model and 

transducer you have connected.

The sonar views available vary depending on the type of 

transducer and optional sounder module connected to the 

chartplotter. For example, you can view the Split Frequency 

view only if you have a dual-frequency transducer connected.
There are four basic styles of sonar views available: a full-

screen view, a split-screen view that combines two or more 

views, a split-zoom view, and a split-frequency view that 

displays two different frequencies. You can customize the 

settings for each view in the screen. For example, if you are 

viewing the split-frequency view, you can separately adjust the 

gain for each frequency.

There are several full-screen views available, depending on the 

equipment connected.
The full-screen Traditional sonar view show a large image of the 

sonar readings from a transducer. The range scale along the 

right side of the screen shows the depth of detected objects as 

the screen scrolls from the right to the left.

NOTE: To receive Garmin ClearVü scanning sonar, you need a 

compatible chartplotter or fishfinder and a compatible 

transducer.
Garmin ClearVü high-frequency sonar provides a detailed 

picture of the fishing environment around the boat in a detailed 

representation of structures the boat is passing over.
Traditional transducers emit a conical beam. The Garmin 

ClearVü scanning sonar technology emits two narrow beams, 

similar to the shape of the beam in a copying machine. These 

beams provide a clearer, picture-like image of what is beneath 

the boat.

NOTE: Not all models support SideVü sonar and scanning 

transducers.
NOTE: To receive SideVü scanning sonar, you need a 

compatible chartplotter and a compatible transducer.
SideVü scanning sonar technology shows you a picture of what 

lies to the sides of the boat. You can use this as a search tool to 

find structures and fish.
