Will Roll-Along increase my survey depth?

Short Answer: No.

Long Answer: The depth of investigation depends on the largest array span during the survey—not the length of the survey line. As such, roll-along will not increase the depth of investigation.

Tip: Since it has the same number of electrodes and electrode spacing, we recommend the Pole-Pole array to get the most penetrating depth.
