filtered and charted by the computer software based on the zone in which the 
data was collected. 
The HydroSense II keeps a table of up to 100 GPS zones in memory and 
searches through this table every few seconds to determine if it is within the 
boundary of a zone.  When it has determined that the user is within a zone, it 
displays the zone name on the main screen (p. 14). 
Zones can be created when data are stored.  When the Store (p. 14) button is 
pressed, and the HydroSense II determines that the current location is not in an 
existing zone, CREATE A NEW ZONE? is displayed. 
To create a new zone, select YES and press  .  To exit without storing, 
press  .  
When a new zone is created, the following screen is displayed. 
Use the     buttons to select the radius to use for this zone and press   
to save the new zone details.  Press   to return to the main screen (p. 14) 
without creating a new zone and without storing data. 
Once a zone is created, the water content data will be stored.  By default the 
zone name will be in the form “Zone xxxxx” where xxxxx is a number that 
automatically increases each time a new zone is created. Zones can be 
renamed and updated using HydroSense II Support Software.
