NOTE: If the transmitter pitch exceeds ±30% (or ±17°)
and/or the transmitter depth exceeds 15 ft (4.5 m),
see Appendix B for more detailed transmitter
location information.
Effect of Pitch on FLP, RLP, and LL Relationship
Note how the RLP and FLP are at different distances from the
LL when the transmitter is at a negative pitch (compare with
figure on previous page in which the transmitter is level).
It is possible to calculate depth (for comparison to the
receiver’s depth reading) using the distance between the
locate points and the pitch of the transmitter. For additional
information, see Appendix C: Calculating Depth Based on
Distance Between FLP and RLP.
