Save space while meeting requirements with the first and only USCG Approved Inflatable Throwable Device Type-iv PFD. Automatically inflates when submerged and can also be thrown fully inflated. Nine times smaller than a life ring when packed, the Throwraft TD2401 is the most advanced Type-iv PFD on the water. Unfortunately it is not Canadian Coast approved and so cannot legally replace traditional ring buoys. You’ll still have to carry those if your vessel requires them. High visibility yellow for search and rescue situations. Easily rearmed and repacked for multiple uses with Leland 24 Gram CO2 with V86140 Bayonet Assembly re-arm kit. Made in the U.S.A.
