Matt M Does this lift bag have a vent on the top?
ROGER B no there is no vent, its not needed. you can dump air by pulling down on the top corner of the lift bag. one could be added if desired. these are great bags, well made.
CHARLIE S No the Blue Reef Lift Bag does not have a vent on top. I must say this lift bag is a great deal you can not go wrong with this one pleanty of lift.I use mine for spearfishing.
KENNETH R No relief valve on this one - basic self-limiting style (excess expanding air vents out the bottom)
MATTHEW Z No. It is the simplest style. No vent. No dump. No one way baffle on the bottom.
NATHANIEL H No vent on top. Bag has an open bottom and can tip over once on the surface if left unattended.
DANE L Matt, this lift bag does not have a vent on top. The instructor for the advanced nitrox & decompression procedures class I'm taking told me that there is a risk of this lift bag taking on water & sinking back down to me in rough seas because of it's design. I'm still looking for a suitable one myself.
