This is the safety sausage that I carry. It is an excellent surface marker bouy that will get you seen (and isn't that the whole ideaa?) It's ruggedly made and has good features such as a dump valve for air, convenient D rings, and is sealed so the air won't dump if it is accidently up-ended. I like the reflective tape on the marker as this can be important in low light or night dive situations. The unit can be attached anywhere on a BC (I keep mine in my BC pocket). It can also serve as a lift bag since it has close to 50 pounds of lift when fully inflated. In heavy boat areas it can also be attached to a line to serve as a surfacing marker as you ascend from your safety stop.

Scuba Diving magazine just did an article on safety devices and for visual surface signals, this was one of the top picks. It is large, so be aware of that. But, you won't need this for every dive. I would not dive open ocean without it.

The only reason I rated this 4 flags instead of 5 was due to size. The unit does not roll up quite as tightly as it could due to the rather large dump valve.

I bought this particular unit because I wanted a safety sausage & a lift bag-in hindsight, I don't need a liftbag often & that makes this unit somewhat overkill-it's very large which make it nice to see but alot to unroll underwater & even when rolled up it's a monster-I prefer to keep things in pockets rather than hanging from my drysuit/BCD & this is so large that it ties up a fairly large pocket. The oral inflator adds to the bulkiness-they could have done this differently to make it roll up more compact. Consider your profile underwater prior to making a purchase.

      Comments about XS Scuba Scuba Surface Marker Buoy (SMB):

      I bought this for my upcoming technical diving course. Needed to get rid of the dinky recreational version and get one meant to be used. It is much larger than the small ones you buy to stick in a pocket and forget about. This is meant to do a job. So, be sure you know the dimensions and have a need/want for something this large. That said, it has a nice Velcro wrap tab and all the other features needed for tec diving. Seems very well built. Time will tell on that. No large manufacturer logo taking up space on the SMB, so plenty of space to stencil your name. The oral inflation valve is not in the picture, but it came with one. This thing is large, so I will be using the baffled bottom to inflate. This seems like a great product and compares with the ones I looked at in the over $90 price range.

      Comments about XS Scuba Scuba Surface Marker Buoy (SMB):

      I got a yellow SMB and for mine the vent plug is much higher then what is shown in the photo. To effectivly use this as a lift bag requires very long arms or the help of a dive buddy.

      But on the whole very satisfied with the purchase, it is very visible and that is the primary reason I got this product.

      This thing is huge. Even rolled up it's big and bulky. Must have for any rescue situation. Very well built. Worth the money. Don't waste your money on anything smaller or bigger. Perfect size. Only wish they gave a pouch for it. The boat will see it, miles away. Has a strap for a torch or strobe.

              This is a great surface marker. Let me tell you why. First, it's HUGE, and that makes it highly visible. Second, it has several inflation options. This SMB is compatible with a low pressure inflator hose, it can be orally inflated, and it has a baffle inflation option that can be used with an octopus. Third, this SMB has an overpressure valve that prevents it from bursting if you inflate the marker underwater. Forth, this SMB has a loop with a metal ring that is great if you want to attach a reel and send the SMB up while on the bottom, or at your safety stop. A good SMB is a very important piece of safety equipment, and this one works very well. Some people may think it's a bit large, and it is. Im my opinion, that is the whole point, I want to be seen once I inflate my SMB.

              Questions about this item:

              Shopper  Why Did You Choose This?
              MATT S  Its huge, and very visible
              Dan J  Will the QD work with Air2?
              Frank L  No, it will not. Only standard BC QD.
              Shopper  Hi, kinda of confused - some comments indicates that it does not have an oral inflation. so does it or does it not have an oral inflation ? for the oral inflation - is it one of those that i can use a LP BC inflator hose as well ? or i can only blow into it (similar to those that you see on aircraft lift vests) ?
              DAVID M  No oral valve. This is about 2 and a half meters (almost 8 feet) of marker buoy, so my lungs, at least, won't inflate it. I only deployed it once. Hold the open end under water to seal, and wrap it around the 2nd stage or octopus. Push the purge valve until inflated and standing up. It has a dump valve to deflate, and no connections for an inflater hose. The feature I like is a velcro flap to help secure the buoy when it's rolled up. However, like every marker buoy I've used, if I'm not careful securing it, it comes unwrapped from the inside out. I've had one occasion of it coming undone during a dive so I trailed it throughout the dive. Regards
