OMS Open Bottom Lift Bag/SMB

New Old Stock!   OMS surface marker buoy, open bottom with no-spill baffle design (won't empty out when it hits the surface), OPV for gas release, heavy strap for connecting your spool/reel or lifting heavy objects.  
I've used 2 of these exact SMBs for over 20 years of diving... and they are still going strong.  I'd estimate they have about 50lbs of lift.  I've lifted plenty of boat anchors with them.
