We have always developed our STS hardware based on 30+ years of field-testing experience as well as feedback from all of our clients around the world. Because we’ve slogged through the mud, rappelled from ropes, and swayed in bucket trucks—all in bad weather—we know that ease-of-use is a must. The software is simple to operate, and the built-in sensor verification routines ensure you’ll collect quality data. With the significant cost associated with field work, the STS4 will pay for itself after just a few uses compared to traditional data acquisition systems.
