Master Surveillant is an integrated approach to learning physical and technical covert surveillance. It leverages the best practices of traditional physical surveillance techniques, combined with powerful techniques innovated by founder Darin Fredrickson. But Master Surveillant is also much more. It is a way of being and acting that can foster breakthroughs in all areas of your career as you become mentally stronger, innovative, and confident. To become a Master Surveillant is to embody a life of self-mastery, forging discipline, resiliency, drive, determination, honor, integrity and courage. This training will not only make you functionally better at physical surveillance, but adaptable to whatever challenges come your way. If you participate in our live field classes, you will learn to be a great teammate, finish strong, and discover your 10x potential.  This will translate into keeping you safe on the street, minimize your exposure to surveillant subjects, and greatly increase the likelihood of a successful case resolution.


Founder Darin Fredrickson was an undercover detective for over 16-years working drug enforcement, weapons and human trafficking, homicides, and retired as a member of an elite surveillance team that targeted career criminals for investigation and surveillance. During his 20-year career as a street cop and undercover investigator, he created the surveillance model for Master Surveillant to supercharge his own investigations. Darin partnered with Ray Siljander to write several criminal justice books, which are published through Charles C. Thomas Publisher, and then began teaching the model to investigators assigned to Federal, State, and Local Law Enforcement agencies, and retail and private Investigators. Investigators with the 5%’er attitude succeeded at an unprecedented rate because of the model and innovative methods they learned. Darin knew through his own investigative successes that the mental aspect of conducting surveillance was just as important as the techniques and strategies utilized to execute a successful surveillance operation.  But the innovation is to combine the mental, physical, and teamwork (when applicable) into an integrated regimen, which is how Master Surveillant was born.

Master Surveillant is the epitome of an accomplished training program that is accessible to any investigator, beginner and elite alike. Whether you operate on a team, or as a solo surveillant, this course is for you. The strategies can be scaled to any investigation, large or small. The starting point is the online Master Surveillant training program, which provides you the fundamentals of physical surveillance before developing physical, mental, and team skills through live field training. Once completing the online training portion, you will want to expand your knowledge and develop the necessary critical skills, which challenge individuals and teams to find their full measure and tap much greater potential… a potential that is often ten or twenty times greater than what they have experienced before. Becoming a Master Surveillant is a rigorous endeavor and not for the faint of heart, it requires an honest assessment of your strengths and weaknesses, and a deep commitment to training and improvement. Day-by-day, in many ways, you will become better and more resilient. Through this program, Darin has taught others how to conduct surveillance and develop the mindset and combine them with the physical skills of strength, stamina, work capacity, endurance and durability. This combination enables you to win in your mind before stepping onto the field and tap the enormous energy that lies deep inside all of us.


Master Surveillant is for government and private sector investigators, and essentially anyone with a desire to learn the skills discussed above to protect themselves and their family against crime.
