What is sett? I thought this was nemo33 at first…

SETT stands for Submarine Escape Training Tank.
This tank is used to train how to ditch a submarine without any air. Basically exhaling all the way up so you don’t die from air expanding inside of you.

great video! always been fascinated with that tower this is really intense stuff!

whenever im just snorkeling in the ocean and then i swim deep down my ears hurt like a bitch. do u know why that is?

Yeah, it’s the build up of pressure on your inner ear. Although you can’t see it on the video, as we decend we’ll hold our noses occasionally and gently blow through them to equalise the pressure – Usually before it  starts to hurt!

My recollection of doing SETT passed a hell of a lot quicker than this video!! but i did it from bottom to top though. I did it a number of times during the 80′s from 10mts, 20mts and 32mts and from 32mts to the top only took about 8 – 10 seconds. now that is a rush!

do you take a big breath before the ascent then blow it out as your coming up? your doing it from 30m what if the sub is at 200m or beyond what happens then?

is the nemo 33 deeper?

you die i guess

yes

thanks.

No, it isn´t Nemo. This one has 25 meters Deep. Nemo has 33 meters, many levels, a little cave and it is larger.

When I dived it, it was 30m deep

But no, it’s not as deep as Nemo33. Or as much fun I’d guess, as Nemo is purpose built for recreational diving and the SETT isn’t.

what are those 2 large tanks for??

That part is what scared my from
Scuba diving. I might brave it someday and go to the ocean.

@mlls100 oh my god i am fifteen and i am already a certified scuba diver and i really want to go to nemo 33 it must be brilliant

were is this place i wanna come here

can somebody tell me were this is please?

@mrchristiangoodall

It’s in Gosport, south east England. Do a search for “sett portsmouth” in Google and it should come up with the website.

Sadly, I don’t think they allow recreational divers to use it any more

@DanFrederiksen

They’re just for decoration. We were of course holding our breath like real men ;-p

@AbsolomDaak hehe

The SETT (Submarine Emergency Tratining Tank) in Gosport is no longer open to the public. Up until recently it was used a lot by the Free Diving clubs as its the only indoor 30m warm water pool in the UK.

In answer to a previous question the “tanks” are actually two air lock hatchs at the bottom which are for the the submarines escape training (which is what the tower was built for).
