Choosing a sonar application
Choosing an appropriate sonar application can improve the quality of your data. As the M3 Sonar has both imaging an profiling capabilities, you will also need to choose either a Profiling, or an Imaging application.
Context
Note
You cannot select a sonar application until the Sonar Head is connected. All Sonar Applications menu items will be greyed out until the sonar is running.
The selection of sonar applications presented in the Sonar Applications menu depends on the current Sonar Head frequency.
The Sonar Applications menu lists various operating modes used for different applications. Each mode has its own pre-defined characteristics, such as differing ranges, angular resolutions, and pulse types.
If you don’t see the sonar application that you need in the menu, you may need to add it to the list. You can configure which applications will appear by opening the Customize Apps dialog box, which is the last item in this list.
Tip
Each sonar application has its own TVG profile. Before changing the TVG settings, select the sonar application you want to configure from the Sonar applications list. Click the TVG button. This button is located on the tool bar.
Procedure
1 Click SetupConnect to start the Sonar Head.
2 Select Sonar Apps from the menu on the top bar.
3 Select an appropriate sonar application from the list.
a If you wish to gather imaging data, select an imaging sonar application from the list.
We recommend a maximum vessel speed of five knots for imaging applications.
Tip
For high-quality images at a short range, use one of the EIQ modes (500-kHz transducer only) or Imaging Enhanced (available on frequencies from 700-kHz to 1400-kHz). We recommend a maximum vessel speed of two knots for EIQ mode and 0.5 knots for EIQ - Fine mode.
b If you wish to gather profiling data, select a profiling sonar application from the list.
Use this sonar application for the automated point extraction of the sea bottom or structures to create a real-time 3D Point Cloud.
c Select one of the test apps to troubleshoot performance issues.
