SurPRO 3500 is based on patented geometry and an inertial stabilizer that enables its performance to approach perfection. These design choices minimize most sources of error in the data collection process to nearly zero.

SurPRO 3500 uses the best accelerometers and encoders available today. To obtain the most accurate elevation profile an additional accelerometer was added to enable correction of any error resulting from cross-axis tilting; bringing the total accelerometer count to 3. Most other profilers use only 1.

In addition, as a result of a total redesign completed in 2011, SurPRO 3500 uses the latest data acquisition electronics and embedded computer components. The components of the new "V2" hardware enable higher resolution and more accurate conversion of sensor analog measurements to digital values used to compute profile elevations. Computations are performed with a new embedded computer that enables greater accuracy in determining profile elevations.

Finally, SurPRO 3500 incorporates mathematical algorithms and second order corrections and mathematical optimizations that are the result of many years of experience developing ultra high performance reference profiling instruments. Creating a profile by collecting data from a handful of sensors on a moving data collection platform may seem to be easy. It isn't. The developers of SurPRO 3500 know exactly what it takes to transform that sensor data into an extremely accurate profile.
