Problems keep being solved in the same tired ways.
It’s time for that to change.
Dr John Leeman

Our Story

Leeman Geophysical was started in 2015 by Dr. John Leeman to provide equipment and services for the geophysical and measurement market. John has a long history of finding unique ways to solve scientific measurement and computing challenges by combining an understanding of the fundamental physics of the problem, a scientist’s view of the setting, and a practical sensing background. In addition to solving problems, John is passionate about effective communication through the use of well-designed data graphics and clearly communicated methodology. We can provide a unique solution to any problem.

Why Orange?

One question we hear all the time is “why are your products orange?” When John was a little scientist, his grandfather loved the color orange and painted all of his tools with orange marks. This not only marked them as his (and kept his kids from permanently borrowing them), but the color made him happy. It’s for this reason we make our products stand out with orange casings, accents, or trim. We’re proud of our products, seeing orange makes us happy, and it means that quality is present. Any company can put electronics in a can, but our sensors are so much more than another silver metal cylinder in every way, including their orange color.
