Description

Port

If set to True, port side data is visible in the View window. If False, only starboard data is visible.

Either Port or Starboard or both must be enabled.

Starboard

If set to True, starboard side data is visible in the View window. If False, only port data is visible.

Either Port or Starboard or both must be enabled.

Altitude line thickness

Set the thickness of the line used to digitize the altitude of Raw data in the waterfall view. Set a value from 1-8.

Playback speed

Set the speed the Playback tools use when scrolling through pings in the Side Scan View (3 is slower, 20 is faster). See Playback controls.

Range scale

The range scale runs across the top and bottom of the View window. In Raw mode the range displays time intervals in milliseconds. In Processed mode, distance is displayed in the horizontal units set in the Tools >Options >Display >Units dialog box.

To display scale:

• Enable to check box to set to “True”.

(The colour of the range scale is controlled by the Measure / Offset Tools setting in the Tools > Options> Display > Side Scan Editor dialog box.)

Selection

Displays the start and end numbers of the range of pings selected in the Side Scan View. To select a specific range:

• type the numbers of the start and end pings, e.g., 255-275

Limit

Set across-track display limits by adjusting the width of the ping in the Side Scan Editor View.

• By default Enable is set to “False” so the entire width of the ping is shown in the window.

• To expand or narrow the view, set to “True” and type a value.

The smaller the number, the wider the ping is stretched.

Colour

• File: Select the display colour for the waterfall view from the drop-down list. (The default is Grey Scale.)

• Reverse: Sonar recorders have traditionally used light colours to represent high signal returns. Select the Reverse option to change the order in the colour map to reflect this practice.

• Colour Range mode: can be set to Auto or Manual. If set to Manual, then Min and Max Values in dB need to be set.

• Any values below the minimum value are assigned colour 0. Any above the maximum value are assigned colour 255.
