4.2.2
Gathering Data in Active Modes
Switch on the Holux and ensure pairing as indicated above. (Bluetooth icon should be blue) Wait for a valid
GPS signal as indicated by the red bar graph next to the Bluetooth icon.
TIP
It is a good idea to ensure the data log is clear before commencing. To do this
press the “i" button. Whilst the depth screen is displayed press and hold the “-”
button. The message:
“Are you sure you want to delete all this data log. Press + key to Delete”
Pressing the “+” key will clear the data log.
4.2.3
Gathering Data in Power and Radio (Passive) Modes
This is done in the same way as in the active modes except that it is not possible to enter the measure mode
unless a valid GPS signal is received from the Holux GPS.
Depth and current are not available in the passive modes but all other data can be saved to the datalog.
Locate the cable as described in the vLoc-5000 user handbook.
Momentarily press the “i" button. A screen similar to the below will be shown:
To save a record press the + button whilst in this screen.
4.2.4
Transferring Data from the Locator to a Computer
To transfer data it is necessary to use the vLoc-5000 Configurator Tool. This is a simple program that can be
downloaded from the Vivax-Metrotech web site at
www.vivax-meterotech.com
. The file can be found under
the Support/Download Library/Others Download.
TIP
To view Google files it is first necessary to install the Google earth application to
your computer. This is a free application which can be found at

4.3 Trimble
ProXT/XH
For those wishing to work with accuracies better than 1 meter, the Trimble ProXT/XH provides a simple and
cost effective solution. The ProXT operates in a very similar way to the Holux in that it has two LEDs
indicating that there is Bluetooth lock and another for GPS lock. Bluetooth pairing is one in the same way as
the Holux described above. Data gathering is exactly the same as with the Holux described above.
4.3.1
Trimble ProXT/XH Setting up Procedure
The ProXT can also be configured for different applications so the first time it is used it should be configured
to operate with the vLoc-5000 receiver.
Install to your computer the Trimble GPS Controller software. This is a free application and can be found at
