Ghost Signal Responses
The locate arrows will change direction and point 
away from the beacon (as shown) as the tracker 
reaches a ghost signal. The distance from the 
beacon plane to the ghost signals increases with 
increasing depth. 
To avoid locating ghost signals, rotate tracker 
parallel to bore path (shown below) and watch the 
solid circle in the field balance bar to get near the 
beacon plane.
