I have one similar to the modern one, but I can’t use my octopus to bring it to the surface.

Mike Pence says:

The ship you are on looks nice

Ali Hartono says:

We simply call it “sosis” (sausage) a nickname frequently use here in indonesia for SMB.

Thank you Alec for your insight into another scuba gear.


Amy Zhao says:

Really enjoyed watching her deploying the SMB. Perfectly done and looks effortless at the same time.

Mike McLean says:

Alec, you rock! Thank you so much for sharing your knowledge. Love your vids!

Michael Frymus says:

I would love to know what you do to ur equickment after a dive holiday, do you take apart your second stages octopus from regulator to wash?

Terence Callaghan says:

Cracking video! Well explained, Thank you!

John Delta says:

MasonZ. says:

the audio is not good enough. wish you could redo, or edit it.

EmpiricalPenguin says:

Thanks for this one Alec, very informative!

crossroads says:

Thanks for the video! I was in Palau last month. 18 dives with Sam’s Tours. How does Palau rank with all of the other destinations you visited? Blue Corner, Blue Hole, and Sandbar were my favs! What were your favorites?

iVlog says:

Great video Alec, I like the fact that the audio is real and not “studio”.
Really enjoying your videos.

Toriless says:

How about when to USE a SMB. There seems to be 8 thousand standards. I got one anyway but am never sure when to use it. Of course I got the reel with clip too. Some people use them the whole dive, some for emergencies, some at the (optional but advised) decompression stop. It’s all a mess. Personally, I would at the latter. It seems like a reasonable time to warn about a diver coming up there but the internet is full of people using them billions of ways.

Agustin Machetanz says:

Thanks Alec, very clear your explanation!

Ted Reitsma says:

First of all, I greatly appreciate these videos and find them educational AND entertaining. For this video I have 2 comments. In very cold water, it should be mentioned that it is best to use the spout to inflate the DSMB and not to use the octopus. The reason is that using octopus can cause a free flow to persist in it due to the already cold temperature and creating a deliberate free flow makes the 2nd stage even colder. My second comment is that there is a much, much safer way to use the inflator hose (which I see no reason to use anyway). You can get an adaptor to connect to the inflation hose that is somewhat like a spout. This will connect to some of these DSMB. This is MUCH safer that blowing up a DSMB with the low pressure inflator as shown and then scrambling to try to disconnect it before you are shot to the surface.

thanks a million
