hey sheahan

the DSS 3' smb is a great smb to learn to shoot with.

Sheahan that's the one I have, I like it, it's small, easy to use, and rolls up tight. Joe has the H one, and he like that too. I think those are the two main ones that people use. For a spool, they are pretty easy to come by, and i don't think there's much difference.

Hey Sheahan-

Good question, and Jake and Matt gave you some good answers. Either one of those smb's will serve your needs well.

A simple 100' spool with a stainless steel double-ender is all else that is needed.

Avoid the stainless spools. Generic plastic or delrin are fine and can be found on sale for relateivly little (~$15 with line if you look around a bit).

The DSS SMB can come with either the LPI or mouth tube inflation end, in my limited playing around I can't tell the difference. They both seem to work the same. With such a small bag (couple liters volume) they are easily inflated orally without disconnecting suit inflators etc.

I find the LPI version easier to inflate. After a long dive in cold water, my frozen lips don't a sufficient seal to push air through the mouth tube inflation version.

Thanks for the help guys! It seems like as long as it has a pressure relief valve, anyone would work fine, whether it’s 3’ or 6’? Thanks for the tip on lpi inflation Richard and Don

One more quick question. I was looking at a Halcyon 4’ SMB, and it has “EMERGENCY” written on the side. Why would they put that on there? If you are shooting a bag as a reference line, you probably wouldn’t want someone on the surface to think it’s an emergency. Any thoughts on this, or do I just not worry about it.

the DSS smb can be inflated via the LPI or orally. from the DSS site:

"A special Notchless Nipple is fitted to the fill stem to allow for inflation using either an LP hose, or orally. This nipple will NOT Permit the LP hose to latch and is ejected when released. "

the 6' bags have a LOT of lift, sheahan. i would recommend learning to use a short one first, to avoid being dragged to the surface... ;)

i'll be at redondo for most of the day on sunday. you're welcome to come down and i'll show you how to shoot my 3' DSS smb.

Sheahan-

Stay clear of the "emergency" bag. That will do nothing but cause confusion and stress on the surface. Get 3' bag with nothing on it, except for maybe SOLAS (refelective) tape.

As far as bag size, Matt covered it well, again. Unless you're deep, a 6' bag is almost a 2 man job. A 3' bag is super easy and can be deployed and launched by a single person in less than a minute.

If you have any more questions, please keep them coming. I'm glad to see you doing your research before you buy, and I'm sure these questions are helpful to others as well.

DSS makes two SMBs: (1) LPI and (2) Oral only.

Here's a picture of the Oral only.

sorry i wasn't being clear. i meant that the DSS smb i linked to in my first reply was inflatable either via the lpi or orally.

The 4.5ft Halcyon bag is huge (I have one) and not easy to get inflated. 6ft is truly giant. They aren't things you want to learn with at all. Smaller is better to start. You'll probably end up with a very large bag if you dive remote site with high current, but until then practice with the smaller SMBs to get the mechanics down.
