Ghosthunters reckon they have recorded the ghostly wail of the Loch Ness monster.
Marquis H.K, 55, and friend Mark Dann travel around the UK visiting spooky location with their ‘spirit-detecting’ kit.
The friends took their dowsing rods, compass and camera to the shores of the famous Scottish loch and asked if any spirits are present.
A video shows the rods moving suddenly and a ghoulish cry can be heard in the background.
The team think this is the howl of Nessie and is strong evidence for the theory that the Loch Ness Monster is a spirit.
The pair were filming an episode of their YouTube series Extreme Ghost Hunters at the time.
Marquis, from Inverness, who works at a Nessie-themed exhibition centre, said: ‘It was astounding.
‘It’s a very distinctive sound and it completely blew us away.
‘It’s a wailing creature sound, and it echoes right across the lake.
‘I’ve had a lifelong fascination with the Loch Ness Monster – it’s incredible that this has presented itself.
‘One of the common theories about Nessie is that it is a spirit, and the sound we heard is strong evidence for that theory.
‘I’m increasingly moving towards believing in that theory. It explains why Nessie has never been proven or detected – plus no living animal could be there so long.
‘Nessie has been spotted, but people might not be seeing a physical creature.
‘We didn’t hear it when we were there but on the recording. I can’t explain that – it’s paranormal.
‘There’s no way that’s a human sound and it can’t be from the equipment. We use manual equipment so it can’t generate any ”fake” sounds.’
The pair started ghost hunting earlier this year – inspired by Marquis’ interest in the paranormal and tour guide Mark’s knowledge of local history and myth.
An occultist named Aleister Crowley lived on the shore of the Loch, at Boleskine House, and some believe he summoned many spirits there.
Marquis said: ‘We have had movement from our equipment when hunting in the cemetery where Crowley summoned many spirits – perhaps he opened a portal.’
