This screen enables you to select/change your data acquisition parameters. For most applications the
default settings are adequate. To access settings for different applications click the small arrow in the
Config Type (
1 ) option.
•
You will see a broad list of application categories. Choose the one that best describes your
application.
•
For example if you are scanning a concrete slab to find reinforcing bars, choose CONCRETE.
Then choose your antenna type under Config Name (
2 ). An X after the configuration name is
used to denote use of an antenna that has its dipoles oriented perpendicular to the normal survey
direction. Common data collection parameters will be automatically set.

Check to make sure that Scans/ft ( 7 ) is adequate for your application. Generally, the more scans per
unit that you collect, the slower your collection speed, the larger your data file and the more stretched
your file will appear. When you are finished, click Next >.

The next window (Figure 15) will ask you to either create a new macro, or attach one that you have
already created. A macro is nothing more than a saved list of data collection parameters. These
parameters include: filters, time range and gain settings. These parameters will vary from job to job,
so it is possible that you will have many different macros for different survey objectives. Common
parameters for your antenna will be selected automatically based on the Config Type and Config
Name that you chose in Step
6 .

you will need to create one. Click the button for Create New Macro and click Finish. The antenna
will initialize, you will see a clock counting a few seconds and then the following window will
