1987: Search Ends For Loch Ness Monster
Βι¶ΉΤΌΕΔ Archive: A major sonar exploration of Loch Ness in Scotland failed to find a monster.
Searchers on Operation Deepscan spent a week on the loch using Β£1-million worth of equipment to scan the lake.
The flotilla of 24 boats did pick up three sonar "contacts" shown on paper as crescent shaped marks.
They indicated something big in the waters below Urquhart castle but this could have been a seal or a group of salmon.
