An annual hunt for the Loch Ness monster has kicked off, with the search being aided by an underwater drone which will map the bed of the loch.
The Loch Ness Experience's yearly "quest" began on Thursday, inviting visitors and enthusiasts to take part in the search for Nessie.
On Saturday, a "surface watch" is expected to involve hundreds of onlookers scanning the water around the 37km loch.
