I have had some success with Vertical Electrical Sounding (VES). This uses electrodes driven into the ground and measures soil resistivity. Multiple readings give a profile of subsurface conditions. It isn't 100%, but improves odds considerably. https://www.agiusa.com/1d-resistivity-survey-vertical-electrical-sounding
