If you mean SMB, as @scubadada has shown...
I call the above, a flag. For me SMBs, DSMBs are the tube things we use on the surface or from depth to mark our location . I use a finger spool with those.
Hi @Dennisrl84
You should become familiar with these. Very important for your drift diving should you become separated from the flag you are diving on. In Boynton Beach, every diver or group has a flag. In West Palm and Jupiter, there is generally one flag with the guide, not uncommon to ascend on your own on your SMB. It is always possible to get separated from the flag, if you are not carrying it.
