6000' Drop Off. You can hear a submarine pinging.

[mattavant]

Listen, I was an underwater dolphin translator and that's clearly not sonar but most likely a sea chipmunk in heat

[krabman]

That's one deep drop off, 6000 feet I'd be scared shitless to dive over it even next to it. Afraid of what might come out of there lol.

[Tommy-gkbh]

This is not a submarine, the frequency and consistency of the pings are approximately 237.98701 htz/s and judging by the time between each ping the “submarine” is exactly 2.394 nmi and this would mean that the “sub” would only be about 3.2 m in length and made of aluminum therefore it is not a submarine, but instead a Fortnite supply drop

I was a Sonar Technician in the U.S. Navy and I'm telling you that is not a sonar transmission from a submarine. It's either from a diver computer (most likely) or possibly a nearby charter boat with a fish finder (much less likely). It is absolutely, definitely not a transmission from a submarine or surface warfare vessel. Wrong frequency, wrong duration, and wrong intensity. Also, the fact that the pitch remains constant indicates that the range is fixed. Given that you are staying close together and you aren't hearing any engine noise from a trolling charter boat, I'm positive that it's your dive computer or that of one of your dive buddies.

And before you say the inevitable "You don't know every sonar in the world", let me stop you right away. Yes, I do. It was my job to know the machinery and sonar frequencies of every class of warfare vessels and common merchant shipping worldwide. So yes, I do know every sonar "ping" in the world. (Oh, and we don't call them "ping". That's just Hollywood)

As an ex marine, ex pilot, ex navy, ex special force, ex seal team, ex president, ex submarine, ex dolphin, that sonar ping was from a water vehicle

[gammaraider]

I dove on the edge of a drop off like that years ago. It’s actually pretty intimidating. One minute you’re skimming the bottom and then suddenly the bottom just disappears from under you. The thing I remember best is the water suddenly turning very cold. Interesting experience!

[CoopersAmputeeLifestyle]

Jesus someone is sucking their tank dry.

[anonydunfgoog]

I dove at one of these places when I was younger. It is scary as hell. If you swim away from the cliff you are facing away from any sort of reference to the ground and you are surrounded by blue. It's disorienting. It's important to keep an eye on your depth gauge!!! The tendency is to swim down even deeper, go down enough and you're never coming up again. Remember "up" is where the bubbles are going.

[tommyi-opener]

I almost suffocated watching this. I was struggling to breathe.

[huntersihelp]

with how hard you're breathing I wouldn't be surprised if your dive only lasted the duration of this video.

[berserkermaniac]

Straight Down... Nothing but Darkness and Pressure...

[LuxuryFlyer]

This is actually from a boat equipped with sonar, not a submersible

[anthonybrowning]

Submarines do not move around the world's oceans by pinging.

[thomash]

"Give me a ping Vasily, one ping only please".

[goalie]

If you listen carefully you can hear a dolphin fart at 205

[bogie]

I'm in the Royal Navy and have heard many sonars. It sounds like a depth measuring sonar to me. Small sharp ping is all it needs.

[maces]

That's from the boat you left from. It's kinda like a fish finder but for tracking novice divers. The crew is making sure nobody is in distress by going to deep.
Basically a diver tracker. You can hear it because it's a very strong wave. They are not looking for a law suit.
I heard the same thing when I was out with my diving class getting my diver certification.

[garystone]

That isn't a sub, that is my ring tone. I was diving there about a week before, and my cell phone fell out of the BCD; I was calling it to find out where it was.

[KaonashiKobayashi]

Frequency is too high, sounds like SR navigation sonar. Sub sonar would be much lower frequency.

[coolspace]

Subs don't frequently ping. That gives their position away. The only time they might transmit is for maintenance, calibration, testing, or maybe during a firing exercise. When they do transmit, it would likely be on a restricted test range far away from people and general marine surface traffic.
