Selection tool buttons

Rectangle tool Rectangle tool

The Rectangle tool is for drawing a rectangular selection on the echogram. It is used mostly for zooming or defining regions.

To make a selection using the Rectangle tool:

  1. Click the Rectangle tool.
  2. Click and drag on the echogram to form a selection over the relevant area.
  3. Click again to disregard the selection.

Note: The Rectangle tool is also used as the "select" tool. It is used to select a region.

Horizontal band tool Horizontal band tool

The Horizontal band tool enables you to make a selection which extends the entire width of the echogram at a defined depth. The selection includes areas beyond the current window border.

To make a selection using the Horizontal band tool:

  1. Click the Horizontal band tool.
  2. Click and drag on the echogram to define the desired selection.
  3. Click again to disregard the selection.

Tip: This is a fast way to define horizontal regions of defined depth across echograms of any size.

Vertical band tool Vertical band tool

The Vertical band tool enables you to make a selection which extends the entire depth of the echogram at a defined time/GPS position. The selection includes areas beyond the current window border.

To make a selection using the Vertical band tool:

  1. Click the Vertical band tool.
  2. Click and drag on the echogram to define the desired selection.
    Note:
    The time or GPS position will be displayed in the ping status/GPS area.
  3. Click again to disregard the selection.

Tip: This tool is especially useful for defining bad ping regions.

Define a region from the cruise track window

The Vertical band tool can be used with the cruise track window enabling you to make a selection which extends the entire depth of the echogram at a defined time/GPS position.

For more information refer to About cruise tracks and Using cruise tracks.

Parallelogram tool Parallelogram tool

The Parallelogram tool is used to make a selection on the echogram in the shape of a series of parallelograms. It is mostly used to select an area parallel to the bottom reflection in preparation for performing a line pick or defining a region.

To make a selection using the Parallelogram tool:

  1. Click the Parallelogram tool.
  2. Click and drag on the echogram in a vertical direction to the desired depth.
    Note:
    This depth will be maintained as you make subsequent selections in the horizontal direction.
  3. Progressively click on the echogram from left to right to indicate the nodes of the desired selection

    - OR -

    Click and drag and release at the desired node.
