On September 30, sonar technology photographed an image of what could be the “most compelling” Loch Ness Monster evidence to date.

Ronald Mackenzie, the director of boat tour agency Cruise Loch Ness, utilized two-year-old sonar technology to capture the photograph roughly six miles from Fort Augustus in the Scottish Highlands. The image was picked up slightly over 600 feet below the surface.

The sonar image — confirmed as genuine by a sonar expert — is large and solid, suggesting the creature measures roughly 30 feet in length. Many have suggested that Nessie feeds on eels and trout in the trenches of Loch Ness.

Loch Ness Monster expert Steve Feltham believes this could be the “most compelling” evidence of the cryptid in history.

“[Mackenzie is] a Highland lad who does not seek publicity and shies away from the fanciful Nessie theories,” Feltham told Daily Record.

Loch Ness Monster Theories

Over time, the Loch Ness Monster has become synonymous with the plesiosaur, a long-necked marine reptile that has been extinct for quite some time.

Famous angler and host of River Monsters Jeremy Wade believes it could be a Greenland shark.

Our very own Zachary Bales discussed the European Eel theory in a previous post.

Other potential theories include the Wels catfish or other residential animals.

One thing is clear: everyone would love to know what is showing up on this sonar image.

If the creature is over 30 feet long, it would be the largest Greenland shark or Wels catfish ever recorded.

Plesiosaurs grew between 5 and 49 feet long, but they’re supposed to be extinct.

And, of course, it might be something the world has never seen before.


The sonar shows a massive animal in Loch Ness. It doesn’t show what exactly the creature is and certainly doesn’t give any suggestions as to what the Loch Ness Monster could be. Still, it is fascinating evidence.

“I definitely think Nessie is an animal,” said Feltham. “I think we’re getting closer to finding the answer.”

Only one question remains: who is going to dive down and find out?


  1. I feel it could be a cousin of the plesiorasaus? We now know that some dinosaurs had fur or feathers so it’s entirely possible that some could have survived in isolated areas?
