3. Lower frequencies couple poorly inductively. When
using Inductive Mode, use higher frequencies in order
to get a good signal at the receiver.
4. Note that the line into which current is induced must
be grounded in both directions for a signal to be
induced away from the transmitter.
5. The transmitter in inductive mode will generate a field
through the air around it as well as into the ground
under it. If the receiver is within about 20-30 feet of
the transmitter it will measure this field instead of on
the target conductor. Place the transmitter at least
20 feet away from the region where tracing occurs in
order to avoid this "air coupling".

6. Generally if you trace a line with an induced signal
checking for a valid depth measurement and a strong
stable proximity signal is the best way to confirm that
you are locating the induced signal in a line and not
the signal directly from the transmitter through the
air (air coupling).
NOTE: If you have been using the ST-510 in inductive mode,
be certain to switch inductive mode off if you are going to
use the unit in direct connect mode. Air coupling can create
very confusing signals if you inadvertently have the unit set
to inductive mode but are trying to use it in direct connect
mode.
