This customer utilized the Casing Compass to complete 420ft of 36" Casing in Anaheim, CA. The bore was completed on line and grade, and the Casing Compass saved approximately 10 auger pulls to check line and grade. The photo here shows the light of the casing compass visible from 240ft away with the naked eye. As the bore progressed, this customer used a theodolite and string lines to sight in on the light to tell if they were right or left of intended line. Well done!!!
