use the iem finder to lead you in the direction of the buried item. Once you get pretty close to being right by it press A. If you don't pick up the item then you an't in the right place, just walk around and press A. Eventually you will pick it up. If this don't work get a Pokemon with the ablity to pick up buried items. (example of Pokemon with this ablity- Poochyena.)
