The biggest hunt for the Loch Ness Monster in over 50 years is being launched.
Drones fitted with infrared cameras are to be flown over the water.
A hydrophone will also be used to detect unusual underwater sounds.
Organisers said volunteers would also look for possible signs of a creature from safe vantage points on land.
The search is to be held on 26 and 27 August.
It is the biggest search since the early 1970s.
It is being organised by The Loch Ness Centre in Drumnadrochit and volunteer research team Loch Ness Exploration.
Members of the public are being urged to become a Monster Hunter Volunteer and join in the hunt.
A Loch Ness Exploration spokesperson said: “Over the 26 and 27 of August, we are calling on all volunteers to support and participate in a weekend surface watch that could provide valuable insights and contribute to the ongoing search and study of Loch Ness.
“We have chosen several different locations around the shores of Loch Ness where you’ll be positioned and asked to patiently observe the surface of the Loch.
“We are encouraging everyone to take part and if you have any equipment, such as drones, that you feel would benefit the search and the team then please feel free to bring it – the more eye’s on the water the better.”
It will be the biggest search for the monster – who also goes by Nessie – since the Loch Ness Investigation Bureau studied the loch in 1972.
The Loch Ness Monster is one of Scotland’s oldest and most enduring myths.
The story of the monster can be traced back 1,500 years when Irish missionary St Columba is said to have encountered a beast in the River Ness in 565AD.
Later, in the 1930s, The Inverness Courier reported the first modern sighting of Nessie.
Explanations for the monster offered in the past include it being swimming circus elephants.
In 2019 scientists claimed sightings of the Loch Ness Monster could be an eel.
