The Tracker 3 software shows the path of the boat as it moves over the search area along with a cascading waterfall of the Pulse 12 readouts and the GPS position associated with each readout. When a target is detected, the readouts and coordinates change color so the operator can quickly see when and where a target is detected. At the bottom left of the screen is a graphical representation of the last 1 minute to 1 hour of Pulse 12 readouts. When a target is detected the line swings up on the graph. In addition to the Pulse 12 and GPS data, other information displayed are the boat's speed, compass heading, and alarm setting. Up to three fish can be displayed on the screen. The Tracker map can be exported as an image with a KML file to allow it to be easily overlaid on other mapping programs (as shown above). All data can be stored on the PC hard-drive or disk.
