- 2 - Steps Required Before Drilling Scan the jobsite for interference. Pick the frequency bands. Pair the locator with the transmitter. Verify data range. Calibrate both bands. Check Above Ground Range. 1. Scan the Jobsite Transmitter/FO With the transmitter off, select from the Main menu, Frequency Optimization then...

- 3 - Your locator can only detect active interference, not passive interference, such as rebar. Lower frequency bands tend to perform better around passive interference. Middle bands can perform better in deeper bores and may have longer steering capability. High bands have slightly less signal strength, but tend to offer better performance around active interference such as power lines.

Wait 10-18 seconds. Data should disappear in 10-15 seconds. Re-enable Roll Offset, if needed. The Aurora display has a built-in app that can walk you through this DCI DigiGuide App method. See the for more details. Below Ground (Mid-Bore) – RRS3 Roll Method Remain at any clock position for at least 40 seconds (sec.) to clear timers.
