How accurate are the results when using ground penetrating radar?
Extremely accurate! Again, our accuracy is dependent upon the type of application in which you are interested. We have found that when scanning with the 1500/1600 MHz antenna (most concrete applications) we are +/- ¼” to the center of the object we are locating and ½” +/- to the actual depth. We have found that when surveying with the 400 MHz antenna (most utility locating applications) we are +/- 6″ to the center of the object we are locating and +/- 10% to the actual depth. Soil moisture conditions and other factors affect the accuracy for the 400 MHz antenna, and these accuracy results are based on over 50+ years of GPR experience.
