Very decent DSMB Pros: 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.

La boya es buenísima. Funciona perfecto. El carrete es más pequeño de lo que me hubiera gustado y el cordel utilizado no me gusto (por ser plano y se riza con extrema facilidad)

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

We used this for two dives last week, and on the second dive the nylon web that attaches to the line sheared and because we were 45' under the surface we didn't really have a safe way to surface and get it back. The current and wind have taken it away.

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
