6ft Deployable Surface Marker Buoy (DSMB)

6ft long deployable surface marker buoy (DSMB).  Overall good condition, air tight, no leaks.  DSMB has an oral inflation valve which can also be used with an LP inflator hose to inflate it.  It is open bottom as well.  Large OPV to allow excess gas to escape if/when the DSMB becomes over inflated on ascent.
