Investigation was carried out by ADU from the Survey Vessel Scimitar in August 2000, within the area of the RAF Rosehearty Bay range. Sidescan sonar survey proved of little value on account of the presence of rock outcrops, but magnetometry revealed two significant and discrete anomalies at N57 41.042 W2 9.247 [NJ 9081 6600], immediately E of Quarry Head. These were at some distance from the current targets, and it was considered improbable that these were items of mislaid ordnance, but they may have been steel target floats which have become detached. A single dive (to a maximum depth of 9m) was carried out by J White on 2 August 2000; no obvious anomalies or archaeological material were noted on the flat sandy seabed.
