Your SOS Dan Buoy is an important piece of safety equipment and needs to be properly maintained and serviced throughout its lifetime.
This is to confirm that the first service of the Dan Buoy is 12 months after date of purchase and subsequent services should be within 12 months following previous service.
Service procedures of the SOS Dan Buoy33 are explained in Manual of Instruction included in the original purchase or click here
The service should be carried out by properly trained personnel.

- 33gram cylinder CO2 inflation system
- UML Auto Inflator and automatic inflation cartridge
Automatic-Latest Pro-Sensor Inflation technology. The Pro-Sensor is fitted with the latest all weather cartridge with the added benefit of inhibiting the accidental ingress of moisture and water spray during hot humid or heavy stormy weather should not activate the inflation system. The lightweight water-activated inflation system requiring a self-contained disposable CO2 inflation system (the same mechanism as an inflatable lifejacket). The cartridge also has an expiry date and it has to be replaced prior to expiry.

- Water activated SOLAS Flashing light
It is activated automatically to output white flashing light when the water sensors contact with water. Under flashing working status, After activated, it is available with the operating sequence “FLASHING-STEADY-SOS-OFF” by the manual switch.
The light can be seen clearly from at least 1.5km in 360° directions so that it can increase the success chance of rescue. The exposed materials are anti-UV and corrosion resistant. The structure is so compact that the light is completely waterproof under 1m depth of water. The clip makes installation easily and firmly.
Please also refer to UML website http://www.uml.co.uk/how_it_works.html
It is important that all users are aware of the type of inflation system fitted and how it activates.
For automatic operation, a full CO2 cylinder and a serviceable cartridge mechanism must also be fitted and not blocked from water entering the system.
We recommended checking the inflator before donning the SOS Dan Buoy (see service window on dan buoy) ensuring the CO2 is not pierced and fully screwed in tightly by hand and that the cartridge mechanism has not expired and is fully screwed on tightly by hand.
Ensure the inflator is in good condition and not damaged and all indicators are present and correct. The UML Automatic system activates when the cartridge mechanism comes into contact with water. The cartridge mechanism is a compressed high-powered spring which is held by a paper element. When the paper element comes into contact with water it releases the spring which pushes a plunger forward, in turn forcing a cutter into the CO2 cylinder. The cutter allows the CO2 to travel through the CO2 gas hole in the inflator head and inflate the lifejacket.
The Pro Sensor® Automatic incorporates the added advantages of an indication system, that:
- Indicates the CO2 Cylinder is pierced.
- Indicates the CO2 Cylinder is correctly fitted.
- Indicates the status of the automatic cartridge.
- Indicates the automatic cartridge is correctly fitted.
- Replacement UML automatic inflation cartridge only (without CO2 cylinder). This inflation cartridge triggers inflation of dan buoys with UML Pro Sensor inflation mechanisms. Replacement of this cartridge in your SOS Marine dan buoy is recommended every third year, but in heavy tropical climate, annual replacement is suggested.
- Please check the cartridge also has an expiry date and it has to be replaced prior to expiry.
Please take care of your SOS Dan Buoy 33 it is an important piece of safety equipment and needs to be properly maintained throughout its lifetime.
The SOS Dan Buoy`s are sold around the world, they all have UML auto inflation system. Please also refer to UML website for information about auto inflation system.
"Your SOS Dan Buoy is valuable it is recommended to store this product inside cabin when your boat is unattended- Also, stow your SOS Dan Buoy in cabin when weather and waves are repeatedly excessive."
Use the Rail Mount Holder to stow your SOS Dan Buoy externally and when not in use store inside cabin.
At SOS Marine we take great care in the design so that many parts can be repaired or replaced if damaged. In most cases this avoids the cost of complete replacement.
Please Note: “Water must run up inside the bobbin to active the inflator, water washing down and over the inflator will not active your SOS Dan Buoy 33.” http://www.uml.co.uk/service.html
The SOS Dan Buoy rail mount holder is an easy to use container made to be mounted on the rail to contain your SOS Dan Buoy 33
In the event of a man overboard-simply flip open the SOS Dan Buoy holder
- Remove the SOS Dan Buoy and throw
- The SOS Dan buoy 33 automatically inflates once in water.

Only requires a 33 gram replacement cylinder and UML activation cartridge
1. Tested to elements of the life jacket standard ISO 12402
As far as we know, it is the only dan buoy tested to elements of the International Life jacket standard ISO 12402
2. The oversized drogue
We have heard criticisms that drogues on man overboard devices were not large enough, from survivors who lived to tell us. They were frustrated at having to swim after devices being blown away from them in severe weather. The self–inflating SOS Marine dan buoy uses an extra large drogue (47″ by 23 ½″ / 600mm x 1200mm) as a result of this input.
3. Webbing grab handles
By having webbing grab loops as opposed to handles allows the swimmer to reach the SOS Dan Buoy and place their arms around the inflated marker for support and flotation, giving an extra sense of security when fatigued.
(NOTE: Holding handles create cramps in the hands. The SOS Dan Buoy has the ability to put your arms through the loops to provide a more comfortable and stable solution).

If you are intending to take your safety equipment SOS Dan Buoy 33 with you on board an airplane you may wish to read the following advice to ensure a hassle free journey.
You may not be aware, but travelling with inflatable rescue products on board aircrafts can be difficult due to the fitted CO2 gas cylinders. These are classed under the International Air Transport Association (IATA) Dangerous Goods Regulations and require you to get approval from the operator before taking them on board. This means that you MUST contact your operator in advance of your flight or booking and clarify with them their position on the carriage of SOS Dan Buoy 33 fitted with CO2 gas cylinders.

Yes, the SOS Dan Buoy 33 has been dropped from 200ft at 60 knots from a helicopter.
Several SOS Dan buoy`s have been successfully dropped from a fixed wing aircraft from 1000 feet.
Do not mount dan buoy upside down
- The dan buoy is not engineered to be mounted upside down.
- It should be mounted so that the deployment handle is up. Another way to say this is that the dan buoy needs to be mounted right side up.
- With handle up, it is easier to grab to readily throw the dan buoy, while also permitting water to easily drain through grommets in the bottom of the dan buoy outer sheath.
- Mounting the dan buoy upside down can permit water to collect in the self-inflation mechanism, which can cause the dissolving pill to dissolve before you need it to. Mount the dan buoy right side up, with the handle upward.
