12. Mark the ground directly below the receiver’s display screen as the RLP. A line between the RLP
and FLP represents the transmitter’s heading.
13. Position the receiver at the intersection of this heading line with the LL passing through the center of
the box on the display and hold the trigger to take a depth reading. This is the current location of the
transmitter.

Three Methods to Verify Depth Reading
Disable HAG, set the receiver on the ground, and take another depth reading. This reading should be within
5% of the depth reading obtained with the HAG on and the receiver lifted. In the prior example, the reading
should be 2.62m.
or
With HAG on, set the receiver on the ground and add the HAG to the depth shown. It should also be 2.62m.
or
If HAG is not being used, note the depth on the ground and then raise the receiver exactly 1m. The depth
reading should increase this same distance. In the example above, the depth would be 3.62m.
See AppendixC: Projected Depth Versus Actual Depth and the Fore/Aft Offset on page 69 and AppendixD:
Calculating Depth Based on Distance Between FLP and RLP on page 73 for more information on depth.
