How deep under normal conditions?
Question by: Greg edwards on Sep 9, 2018, 10:50 PM Link
This model is capable of diving down 250 feet. If you are referring to detection depth, it would vary depending on which coil was selected, but with the larger coil, you may expect 12-inches of depth depending on ground conditions, as well as the size and composition of the target, as well as the operating frequency selected, and the sensitivity.
