The PADI Surface Marker Buoy Distinctive Specialty Course
Whether you’re planning on coastal diving in the UK or on your holiday, having a Surface Marker Buoy (SMB) will increase your safety and comfort and will alert boat traffic and other divers to your location.
The Fun Part
If you’re ever involved in drift diving from a boat then a delayed SMB will allow your boat skipper to follow your dive and pick you up promptly upon surfacing. They are also a great visual reference on your ascents too. 
The PADI SMB specialty course will teach you the safest and easiest techniques to efficiently deploy a delayed SMB whilst static underwater and also whilst swimming
