For a combined geophysical survey of the waterbottom (UXO, archeology and obstacles), T&A Survey has prepared the magnetometer Scan Fish to perform a survey simultaneously with the subbottom profiler. In an earlier stage of this project, side scan sonar was used in combination with multi-beam echo sounder.

The TISA 2D Borehole Radar, developed by T&A Survey, is a simple, safe and clear way to collect data about the subsurface. The TISA 2D can be used in a variety of shallow and deep underground applications where surface radar is not possible. In 2020, the T&A developed TISA 2D was leased by a client from the United States for the execution of two projects: a gold mine in Colorado and a bridge in New York.
