4.2 Monitoring
The Monitor feature displays real-time information, allowing active tags to be monitored or tracked. A
sample of how the screen appears in Monitor mode is shown below with labels identifying the information
shown on the screen. Further explanation of the information is given in the section 6.4.
4.2.1 Monitor Screen
4.2.2 Manually Tracking a Tag
Tracking a tagged marine animal requires a directional hydrophone. The VR100
receiver is compatible with the VH110 directional hydrophone. The directional
hydrophone must be mounted on the end of a pole so it can be rotated. It’s also
helpful to mark which section of pole is facing in the same direction as the black,
shiny section of the hydrophone that’s surrounded by cork (see arrow in photo
above). This black section is the signal sensitive section of the hydrophone.
After a channel in the VR100 has been setup to detect the tag (see section 2.3) and the tag has been deployed,
use the steps below to track the tag using the VR100.
