Traditional geophysical instruments include ground-penetrating radar, earth resistivity meter, infrared, and sonar, to name a few. This is an area in which I have very little knowledge and practically nothing unique to offer. Thus, you will find that most of the links presented here simply point to other web sites. I apologize for the lack of information on this page, and as I learn more and find more resources I will post them.
