The really clever bit is in the mouth where our unique self-sealing baffle - or duckbill valve - is forced shut, forming an airtight seal, on inflation.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe SMBC rolls up neatly and can be stowed in a pocket, attached to an external D ring or wrapped in the dedicated SMB velcro pouch at the rear left of the AP Commando and Commando Explorer.\u003c\/p\u003e\n\u003cp\u003eAt 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.\u003c\/p\u003e\n\u003cp\u003eA message slate, ID marker or reflector can be tied to the top eyelet.\u003c\/p\u003e\n\u003cp\u003eDimensions: 1.4m long x 20cm wide\u003c\/p\u003e\n\u003cp\u003eRolled: 23cm wide x 8.5cm diameter\u003c\/p\u003e\n\u003cp\u003eWeight: 190g\u003c\/p\u003e\n\u003cp\u003eVolume: 11.2 litres\u003c\/p\u003e\n\u003cp\u003eAvailable in Red and Yellow.\u003c\/p\u003e","brand":"AP Diving","offers":[{"title":"Red","offer_id":57518047396213,"sku":null,"price":44.0,"currency_code":"GBP","in_stock":false},{"title":"Yellow","offer_id":57518047428981,"sku":null,"price":44.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2284\/4832\/files\/accessories-general-surface-marker-buoys-buoy-red-apdiving.jpg?v=1787401841","url":"https:\/\/sandfordanddowndivingplymouth.com\/products\/ap-self-sealing-smb-surface-marker-buoy","provider":"Sandford \u0026 Down","version":"1.0","type":"link"}
