The DMB4S features a steel-tipped inflator valve and can be inflated using a BC low-pressure inflator hose or by mouth.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThe closed-circuit construction helps prevent air from escaping at the surface. An over-pressure valve (OPV) helps prevent overinflation and allows air to be released when needed. The buoy has a nylon D-ring at the top for attaching a light or slate and a stainless-steel D-ring at the bottom for attaching a spool or reel. A utility pocket provides space for a finger spool or other small items. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e45\" long × 5\" wide\u003cbr\u003eApproximately 8 lb of lift\u003cbr\u003eClosed-circuit construction\u003cbr\u003eSteel-tipped inflator valve\u003cbr\u003e200 Denier polyurethane-coated nylon\u003cbr\u003eNylon top D-ring\u003cbr\u003eStainless-steel bottom D-ring\u003cbr\u003eUtility pocket\u003cbr\u003eOver-pressure valve (OPV)\u003c\/p\u003e","brand":"Dive Alert","offers":[{"title":"Red","offer_id":50524526772307,"sku":null,"price":46.95,"currency_code":"USD","in_stock":true},{"title":"Yellow","offer_id":50524526805075,"sku":null,"price":46.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/1778\/4403\/files\/dmb4-s_1000x_05d085fb-e618-4d95-ab5c-9c7e930c6d7a.webp?v=1790191207","url":"https:\/\/shop.yayscuba.com\/products\/dive-alert-dmb4s-surface-marker-buoy-45-closed-circuit-smb-steel-inflator-valve","provider":"YAY Scuba","version":"1.0","type":"link"}
