Unfortunately it is not that easy as a dyke follows weak areas in the rock (i.e., cracks, fractures, etc) as opposed to volcanic flows sedimentary units, etc that get deposited in semi-flat "sheets" so therefore you have some control.

However, in some cases, if the dyke is a lot different than the surrounding country rock it will show up on some types of geophysical surveys. Is also helps if it is a large dyke or the resolution of the survey is small.
