Target Steering
The maximum distance that the Eclipse receiver can be placed out ahead of the drill head for Target
Steering is 35 ft (10.7 m). Over this 35-ft range, the following parameters apply:
¾ The maximum depth change is approximately 4 ft (1.2 m).
¾ The maximum pitch change is approximately 14%.
To determine if your desired target depth is feasible:
1. Use the Eclipse receiver to obtain the current transmitter depth with respect to level ground surface.
2. Subtract the current transmitter depth from your desired target depth to obtain the desired depth
change.
NOTE: If the target depth is above the transmitter, then the target depth number is positive; if it is
deeper than the transmitter, then the target depth number is negative.
3. If the desired depth change is less than 4 ft (1.2 m), then you can program the desired target depth as
the target depth (see next section, “Programming Target Depth”). However, if the depth change is
greater than 4 ft (1.2 m), then the desired target depth is not feasible. You will either have to pull back
to increase the available horizontal distance or you must drill toward a different target.
NOTE: DCI does not recommend using the Target Steering function in dual-low (DL) mode.
Programming Target Depth
1. Toggle to the Configure menu item from the main menu screen on the
receiver, and click the trigger.
2. Toggle to the Target Depth menu item, and click the trigger. You will see
an input area similar to that shown in the figure to the right.
3. Enter the correct target depth number using the toggle. The number must
be in decimal format corresponding to either feet or meters. You do not
need to enter a negative sign when programming the Eclipse receiver with
the target depth number.
NOTE: If you are using FT/IN Units for your depth measurement units, you must enter the target
depth number in feet in decimal format not in feet and inches. You do not need to change
your depth measurement mode.
