to a minimum of six degrees. Sector Steer defines

direction of the center of the sector. This direction is

limited by the width of the sector (i.e. a sector of 90

degrees width can only be pointed in the 45-degree

direction). Drag the slide bars to change the settings.

Scan Mode and Method

For scanned displays, PC/View provides several

scanning options. To adjust the scanning Mode and

Method, select Scan from the Adjust menu.

In its Normal scanning mode, PC/View will send out

30 forward beams and give medium resolution. De-

tail mode offers the maximum resolution with 90

beams. Fast mode uses 15 forward beams and pro-

vides the fastest update but the lowest resolution.

PC/View allows for two scanning methods; a tradi-

tional Swept mode and a Hopped mode where the

beam direction hops to different areas in a pseudo-

random fashion. Hopped mode is useful for getting a

faster idea of changing forward conditions, particu-

larly at short ranges.

For the DOWN display, PC/View can show a high-

resolution Zoom of one quarter of the depth range.

The high-resolution Zoom is useful if you want to see

extra detail on the bottom or in areas above the bot-

tom.

To activate the zoom, click in the Zoom On box. PC/

View will split the screen and begin to display one of

the seven available zoom sections in the left half of

the display. The standard display will continue in

the right half of the window with a highlighted sec-

tion in the scale bar to show the location of the

zoomed section. Select a zoom section by moving

the slide bar up or down.
