Proper Sensitivity Setting


When first turning on a MagHorn, the unit produces a high pitch tone for approximately 1 second.  This allows it to condition itself to the earth's magnetic field.


Use the lowest sensitivity setting possible when you start your search.  This will help you to better isolate the intended target.  There are many magnetic fields floating around and if the sensitivity setting is too high, you may get confusing signals.


The MagHorn produces a sharp change in pitch when it finds highly magnetic materials such as property markers, mag-nails, and valve box or manhole covers, etc., even at minimum sensitivity.


Avoid turning up the sensitivity until you are sure of the target's location and need to search deeper.  


Practice on known objects around the office to get used to which settings work the best in your application.
