About Us

Since 2001, we've been providing Ground Penetrating Radar (GPR) services to thousands of clients throughout the USA, Canada, and Mexico. Our client list includes large contractors, utility contractors, municpal, and government organizations.

With a cirriculum created through real world experience and refined over more than a decade of classroom and field instruction, we specialize in taking the fear out of operating GPR through a linear, ground-up training approach that stresses a handful of key concepts.

Students learn practical solutions to routine GPR operations as well as how bad operating habits are formed, all while gaining an appreciation of the importance of proper operation. We offer a variet of training solutions to meet the varied needs of our clients; everything from daily training to six week training programs at your location, or our headquarters in Minneapolis, Minnesota. With a schedule that's sensitive to your need to keep employees productive and a price that's highly competitive, it includes both knowledge testing and hands on real jobsite experience.

What Type of Training Do You Provide?

We offer courses in three separate areas of operation: high resolution concrete imaging, utility locating, and geophysical explorations. You can choose one course or all three.  When graduating from the course you will be at minimum, Level I (GPR) technician certified.  More information regarding Level I, II & III (GPR) certification can be found HERE.

What Equipment Do You Use?

Any GPR system can be used (GSSI, Sensors & Software, Mala, IDS, etc.) for any NGPRU course. We do recommend the student start out by completing the available manufacturer training course at their facility prior to enrolling at NGPRU. Our courses focus on set guidlines of GPR scanning procedures, screen interpretation, and understanding limitations, so any GPR system can be used.

How Long Is The Training Course?

We tailor the training course to the clients needs. Courses range from one day to six weeks.

Where Does The Training Take Place?

NGPRU courses are held at our corporate headquarters in Minneapolis, Minnesota. We can also send and instructor to your jobsite or location for training.

What is a Level I, II, & III (GPR) technician?

The National GPR University (NGPRU) certification is a non-accredited program that was developed to provide standardized training through general and specific examination guidelines concurrent with American Society of Nondestructive Testing (ASNT) requirements.  We are working on getting NGPRU certified as a training facility through ASNT, however accredited status is currently under review. 

The following is an overview of suggested certification levels:

The GPR Level I should receive the necessary instruction and supervision from a certified GPR Level II or III individual.


  • Possess a manufacturer Operator Certificate
  • Possess a NGPRU Level I Certificate


Individual should be qualified to set up and calibrate equipment and to interpret and evaluate results with respect to applicable codes, standards and specifications.
