button. There will be a short delay (depending on network bandwidth) while the profiler is

5.1.21. Measurements
When the mouse pointer is within the cone on the Gemini data display measurements can
be taken from the display. A single click on the cone will show the position of the click.
Clicking at one point on the cone and holding the left mouse button down whilst moving the
mouse will give a measurement between the two points.
When any measurement has been taken, clicking outside the cone will turn the measurement
off.
5.1.22. Warnings
Out of water
If the Gemini detects that it is not immersed in water, the warning “Out of water” will be
displayed in the centre of the scan image:
The sonar will continue to operate at full power during a 20 minute countdown period. During
the countdown period, toggling the
Online
button will reset the timer back to the start or
immersing the sonar back into water will clear the warning.
