4ft Red Scuba Diving SMB, Open Bottom Surface Marker Buoy with Safety Sausage with 49ft Alloy Dive Reel and Double-Ended Bolt Clip for Underwater Sports-Gray

Very decent DSMBPros: multiple ways to inflate (mouth, inflator hose, regulator). Reflective tape on top. Heavy duty material and construction. Aluminum finger spool. Stainless swivel. Purge valve. 60ft of line. Stanless d ring attachment. Velcro and bungee keeps it securely rolled up.Cons: spool is small for 60ft of line making it difficult to get clip through holes (I cut 10ft off which helped resolve the issue). Loop to attach to smb d ring is on the small side but workable. A bit on the bulky side. Takes a number of breaths to inflate (easier to do with regulator).Overall very satisfied with this DSMB for the price point.

I am happy with this DSMB. It has already been on one dive with me, and it held up well.I do wish the spool was a bit bigger - it works well for me.

This SMB is a great size and made from good quality material. Inside the base of the SMB there is a plastic seal that prevents air from coming out once you have put it inside, however, this means you have to really purge alot of air for it to get inside (if you are using the open bottom to fill it up. This also means it takes a little bit more time to emoyt the air and any water from the release valve after use.The reel and string is sturdy and of good materials. One downside is that the reel is a little bit too small so the wound-up string, blocks the holes that you would put the clip through to attach it to gear. This can be fiddled with to make it work.With all of that said, it is a great purchase and i like the design of everything. It might just take me a bit more practice to get use to it. It is a great price for the quality. I probably wouldn't recommend it for a beginner, but someone who is a good diver and is happy to practise with it to get used to it may like it.

Already 4 dives in with this little guy and really pleased. Good quality, weight at the bottom, durable material, spool holes are a bit small for the clip, but I used another clip that I have and it works well.

A really "fat" sausage. Extremely bulky. Barely 4 foot in length, but over 7" wide. the open bottom designed for inflation with a regulator was sealed with some sort of plastic wrap that I was unable to pry open. I did not see how one could inflate the smb with a free-flowing regulator or octopus. Not for me. Returned it.

This smb has a few ways to inflat. Quality is very good. It feels more than what I pay for.If you're debating if you need one, the answer is YES. Both you and your buddy needs this. I just got back from a liveaboard. 2 people got carried away by current in between 2 Islands to the other side. We sent boats out to look for them after all the other divers came back. They kept on drifting and was 1.5 miles from from the boat before they got spotted... they didn't have snorkels or smb...... almost impossible to spot them in the open sea. Yes please get smb

The DSMB seems to be of decent quality. I have yet to test it in open water, but preliminary land tests seem ok.The spool however is much too small for any diver that does not plan to deploy at basically max of 30 feet. First off, the spool of cord it comes with is not 49 feet, but closer to 42 feet. Then you have to remove about 15 feet of cord in order for your bolt snap to fit through the holes of the spool easily. That leaves you approximately 25 feet of cord left, 30 if you push it. This spool may work for beginner divers who do not plan to go very deep and/or for snorkelers, but for the majority of scuba divers out there, this spool is just too small.

Good setup, worked great.
