The AP Diving SMBC (Surface Marker Buoy - Closed) is the original self sealing divers dSMB. This self sealing SMB allows divers to deploy at depth on an ascent or inflate on the surface prior to descent on a drift dive! at 1.4m in length it is easily spotted from boats and is one of th emost useful pieces of safety equipment a diver can carry.



AP Diving Self Sealing SMB - SMBC For Divers

The ORIGINAL and The BEST DiverS SMB - Surface Marker Buoy
The AP SMBC - Surface Marker Buoy Closed - is the original self-sealing Surface Marker Buoy for divers - much copied but never bettered.

The SMBC is easily inflated by divers by simply purging a second stage, or other airline, or exhaling in the open end when underwater. The really clever bit is in the mouth where the AP Diving unique self-sealing baffle - or duckbill valve - is forced shut, forming an airtight seal, on inflation.

The SMBC also features a stream-lining flap which folds back over the mouth and prevents any sea-anchor drag effect when used in a current.

The SMBC can be used as a delayed-action SMB or it can be inflated at the start of the dive and towed as a standard surface marker.

The SMBC rolls up neatly and can be stowed in a pocket, attached to an external D ring or wrapped in specifi SMB pockets or bungee fittings.

At the surface, the SMBC is pulled upright by tension on the line and clearly marks the diver's position. The baffle prevents air spillage and the buoy remains inflated making it easy for the surface crew to track the diver or for the diver to hold aloft and wave if separated from the boat.

A message slate, ID marker or reflector can be tied to the top eyelet.

Dimensions: 1.4m long x 20cm wide.

Available in Red, Red & Yellow or Yellow.

Customer Reviews

  Best SMB I have found  The SMB is so easy to use and becuase it seals it means Ive used it for proper drift dives, ascents on boat dives which was easy to fill and deploy and its great on the surface to ensure the boat can see me. Ive got hi viz red but the red yellow also seems to be quite visible.  (29/04/2014) Andy - Plymouth


  Every Diver Should Have One!  Every Diver diving from our Centre's is required to carry and SMB. Either to use as a marker on a drift dive or ascent marker on a wreck dive. The reliable Buddy SMBC does all this, if your on the surface by keeping it upright in the water its a great safety device to ensure the boat can see you!   (29/04/2014) Mark - Teign Diving Centre


  Simple to use is best!  excellent SMB from AP valves or whatever they are now called. Easy to inflate works well on drift dives as well as deploying it on ascents. I like me yellow and red version as its easy to see according to the boat skipper anyway, and they are the ones who count :-)   (16/06/2014) Matt - Leicester
