GoPro’s Ocean Drop Reveals Shocking Secret That Made Man Fear for His Life

GoPros these days? Man, it’s like every time you blink, there’s another wild underwater video popping up that somehow manages to blow your mind all over again. You’d think after a while, with just a waterproof case, a stick, and some water, there’d be nothing left to surprise us—right? Wrong. Sometimes, when you drop that little camera off a jetty, you don’t just get the usual fish parade or a sunken shoe. Nope, you might just catch something that makes you pause and go, “Wait, what the heck is that?” Like, imagine dipping your camera into the murky green tides of Port Noarlunga in Australia and seeing what looks suspiciously like a sea mine chilling next to one of the jetty’s pillars. Yeah, talk about an adrenaline spike! There’s something thrilling about poking around the unknown depths —but maybe next time, we call the Coast Guard before playing bomb disposal expert. Curious? Here’s the full story: LEARN MORE.

When it comes to amazing GoPro footage today in 2025, we’re not really short on options, yet each video posted online continues to be as shocking as the last.

It’s simple, all you need is a waterproof case, the GoPro itself, a pole or line, and a body of water that you want to see into.

Sounds easy enough.

But sometimes, you end up seeing things that you wouldn’t expect to see.

On the other hand though, there are people in the world who think it’s a good idea to strap GoPros to some of the world’s most brutal predators. To each their own, and all that.

But one man, who like many others decided to use his camera to explore the ocean by dropping their camera off a jetty in Port Noarlunga in Australia, came across something he least expected.

YouTuber Dusty Sands decided to explore what was below the seawater in a video titled ‘Dropping My Gopro Into Deep Water WHAT..IS..THAT..?’

He asked in the description: “SOMEONE TELL ME WHAT THIS IS?”

Essentially, the support stands of the jetty had formed its own environment, and he was curious to see what was really down there.

Straight away, below the surface, the water appeared green-ish and murky, before the camera caught the sight of something daunting.

In the frame, a large, round object was seen alongside one of the stands, with the round object featuring a number of spikes and a chain leading down beneath it, deeper into the water.

He wrote in the description: “Dropping my Gopro off the side of a jetty in Port Noarlunga. We looked back at the footage and kinda got freaked out when we saw it. We tried dropping the GoPro in at the same spot a few more times but never showed up again..”

Finding Nemo fans will be familiar with the sight, as it looks just like a sea mine.

In fact, people in the comments were so worried about the possibility of this, that they urged him to contact authorities over the discovery.

One user commented: “Strongly suggest reporting it to the coast guard btw, that Is a live naval mine that could take out that entire dock if triggered from a hit.”

“Bro out here making the sea seem 3x scarier than it already is. I sure hope that isn’t an actual live mine, or if it is, that coast guards take care of it,” another pointed out.

A third wrote: “The pressure pins are NO JOKE, that would’ve destroyed whatever the building was decades ago. Should’ve called the coast guard.”

Given that they couldn’t find the object again and no news has been reported of an explosion at the jetty, we’re safe (so far).
