Geophysical Services LLC (Established 1985)
A geophysical service company.
Without doubt, Geophysical Services LLC has a hands-on approach. The geophysical service provider focuses on near surface applications that include environmental issues, mining, archaeology, and engineering. Thus, it is common practice and straightforward for the company to provide well established geophysical methods like those discussed in this web site, to agricultural facilities, farmers, and professionals.
K. D. Jones Instrument Corp started in the 1980’s
A geophysical equipment rental company.
K. D. Jones Instruments transitioned from a company specializing in equipment sales, B. R. Jones & Associates, to one that sold and rented geophysical equipment. Large companies as well as individuals throughout the world rent geophysical equipment. While many sales and rentals are within North America, most are within the United States. Customers rent from us because of our customer service (generally available 24 hours a day and 7 days a week) and working knowledge of the equipment we sell and rent.

One of many disclaimers
I must point out that much of what this site discusses is based on past experiences and reflects opinions. While the laws of physics behind the geophysical methods are well-defined and entrenched in theory, the problem for us, is whether or not we can understand and properly interpret the acquired results. The equipment responds to the earth. It is sometimes difficult to appreciate or interpret what the instruments are telling us.
This site was built with the best intentions. Though great effort is taken to provide good information, the reader is being notified that there is always the potential for a misunderstanding or misinformation. Only those who accept this and who agree to the terms and conditions are permitted access to this site. It is the reader’s responsibility to contact us with errors. This is different than if you don’t like what you see. Clearly, this site won’t tolerate bad behavior. Consequently, this site and the contributors are not responsible or liable for how the opinions and information are used or misused.
