Off-Track Locating

Target Steering

The

Target Steering

®

locating method allows the Falcon receiver to be placed ahead of the drill head and

used as a steering target. It works especially well to avoid rebar that is causing signal interference,

if

the

receiver can be placed beyond the rebar area.

In general, Target Steering should be used to

maintain

a bore path,

not to correct a significantly off-course bore. If needed, use front
and rear locate methods to get back on course.

Locate Points (FLP & RLP) and Locate Line

Page 37

In situations with significant pitch changes, such as during the entry/exit or areas with changing topography
and elevations, the up/down steering information on the remote display may not be accurate. In these
situations, only the left/right steering information should be considered accurate.

After learning the concepts of Target Steering, practice its use

before

using on a jobsite where

time and money are at a premium. If you need further assistance, please contact DCI
Customer Service.

The Falcon Compact Display supports Remote Steering, which provides left/right steering
guidance but not depth. For Target Steering at the drill, DCI recommends the Aurora
touchscreen remote display.
