"What should I do if I have an unexpected "hot" survey"?

1. Check  the nearest geomagnetic activity (USGS here at left for North America) 

2. Repeat your survey to eliminate "noise" from possible tool movement.

3. If 1 or 2 do not return to previous levels for Btotal and Dip, POOH 5 ft and repeat the survey. 

If there is significant change in Btotal and or Dip in Step 2 or 3 please  call us at 

+1 903 600 0842 (24/7/365 with notice).
