STEEP AND DEEP
When a transmitter is level (zero pitch) underground:
the locate points (FLP and RLP) are at equal distances from the
transmitter
depth displayed on the locator is the actual depth, and
the Locate Line (LL) indicates a position above the transmitter.
1. RLP
2. LL
3. FLP
When the transmitter is pitched up or down, the transmitter signal
fi
eld also
tilts.
When the transmitter is pitched down (negative pitch), the locate line on the
screen re
fl
ects a future position of the transmitter, assuming the transmitter
stays on the same trajectory (projected depth).
When the transmitter is pitched up (positive pitch, shown below), the locate
line on the screen re
fl
ects a position behind the transmitter.
The depth reading on the locator is based on the projected depth point,
which is not the same as the actual depth of the transmitter.
