Seafard 4ft/5ft Scuba Diving Open Bottom Surface Marker Buoy (SMB) with 49ft/98ft Finger Spool Alloy Dive Reel and Double Ended Bolt Clip

This semi-closed SMB itself is well made. It is 18 cm wide (7"), requiring two large breaths to inflate tight at the surface. It would be easy to deploy from 10 m depth (or lower) on one breath. I'd expect that those deploying from 5 m would probably want to use the bottom opening to avoid undue impact to buoyancy while inflating. The bottom is slightly weighted to keep it somewhat upright, and these weights can easily bend to hold the bottom open.The spool is tiny at 54mm diameter, 35mm wide, with a 26mm hole (2 1/8" D, 1 3/8" W, 1" H). It is fully wound with flat line, and the holes are completely blocked. You will have to remove about half the line to gain access or just substitute another spool. The double-ended snap is 9 cm (3.5") with stiffer springs than I expected (nice). I'd say it's still a good deal even without the spool.

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.

It's a SMB, and they are all pretty much alike. While some may whinge about the "extra features." I like that I have two ways to fill it (the opening at the bottom is pretty standard). I also like that I can dump air pretty easily. Nice color and the reflective tape is great for night visibility. All in all, its great!

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.

Heavy duty metal construction, easy to use. Swivel is a nice touch. I use it pull a small dry bag and flag when I go free diving. I appreciate the small size compared to the big clunky plastic hand reels.

I was not expecting this product to be of such high quality. The surface marker is outstanding. I wish the reel had a larger diameter.

Seems to work properly. I haven't tried at scuba diving but seems to work perfectly. You can inflate it manually or with your regulator. Easy to deflate. Cord also good is material. The only complaint not important is that I asked RED and this is more like ORANGE color. Again, this is not important. Just dive safe!

It has all the features you actually want.But this is also the problem for me that it has to many.For a 4 foot safety saugages you do not need a opening at the bottom to deploy it.All in all the product does what it is supposed to do.I have not had it in the ocean enough to comment on the actual quality.

Exactement ce que j'avais commandé. Reste plus qu'à l'essayer dans l'eau.
