Using the SR-24's Mapping Feature
The SR‑24's mapping feature provides a fast, intui‑
tive way to find the Sonde's position underground� The
Sonde's dipole field is similar to the Earth's magnetic
field, with two Poles and an Equator� The SR‑24 uses
icons to represent the position of the two Poles and the
Equator� Finding and marking the Poles and Equator can
give you a better picture of the Sonde's position under‑
ground�
To map the location of the Sonde, follow these steps:
1� Follow steps 1 through 6 in the previous section�
2� Locate the first Pole�
As you approach the Sonde, either a Pole icon or
the Equator Line appears inside the Active View
Area� If you see the Equator Line first, move to the
left or the right until a Pole icon appears�
3� Center the Pole icon in the Cross Hairs and mark its
position with a red marker chip�
Note: The Pole's location is most accurate when the
Lower Antenna is touching the ground and the re-
ceiver's antenna mast is held vertical.
4� Locate the second Pole�
Move the receiver a few inches off the Pole until the
Pipe Direction appears� Two Sonde Equator icons
appear along the Equator Line once the first Pole
has been located, to indicate the Sonde's location
is near�
Walk along the pipe in that direction� The second
Pole appears after you cross the Equator� Mark the
location of the second Pole with a red marker chip�
5� Locate the Sonde�
Move back toward the Equator� Align the receiver
between the two Poles, center the Equator on the
Cross Hairs, and mark the Sonde's estimated loca‑
tion with a yellow marker chip�

6� To verify you have located the Sonde, make sure
the Signal Strength drops when you move the re‑
ceiver in any direction�
Note: Always verify your result by locating the point
where the Signal Strength is highest and marking
the Sonde at this location. If the sonde is horizon-
tal and not tilted, the equator will be at the point of
maximum signal strength.
