These kits recharge the dan buoy as well as inflatable life jackets with UML Pro Sensor Mark 2. Using the parts in this kit, servicing your SOS Marine dan buoy is recommended every third year whether or not you have deployed it.

Your complete recharge kit includes:

Some surfers buy our recharge kits for big wave flotation vests or wet suits. This recharge kit includes the parts you need to service your SOS Marine dan buoy after use in training or rescue deployment. Every third year replacement of these parts is suggested, whether or not you have deployed the buoy; you can easily install these parts yourself.

Please Buy More Than One

Your dan buoy or inflatable life jacket can save someone’s life, and not just once! Practice deployment. You will not regret it. Have spare recharge kits on hand; the inflatable dan buoy and inflatable life jacket are reusable, but only if you have spare recharge kits on hand.

How It Works

After you throw the dan buoy into the water, a rapidly dissolving part in the cartridge or bobbin dissolves within seconds due to a paper disk. Until it dissolves, this dissolvable part restrains a spring loaded mechanism capable of puncturing the CO2 cylinder. When the CO2 cylinder is punctured, the gas within is released into your dan buoy or life jacket. Within seven seconds, the SOS Marine dan buoy self inflates. For complete dan buoy information, including a user manual with servicing instructions, click to the man overboard buoy page.

Product Literature



If Just Marine shipped your dan buoy in the USA before 2014-12-01, your dan buoy has the Halkey–Roberts mechanism; if shipped after 2014-12-01, your dan buoy has the UML inflation mechanism.
