Surface Marker Buoy SMB, 4FT Scuba Diving Signal Tube with Dive Flag

• Safer Ascent for Beginner Divers – Built with a large over-pressure relief valve, this surface marker buoy automatically vents expanding air during ascent, reducing the risk of sudden rupture caused by accidental over-inflation—ideal for new and recreational divers.
• Durable 210D Nylon with TPU Coating – Constructed from heavy-duty 210D nylon with TPU coating and reinforced double-stitched seams, delivering reliable sealing performance and long-term durability for repeated dives.
• 3 Easy Inflation Options Underwater – Inflate by mouth, second-stage regulator, or low-pressure inflator hose. Designed for quick deployment during drift or safety stops without requiring special tools.
• Essential Surface Safety Marker – Helps surface teams and boat traffic easily locate divers. Ideal for scuba diving, freediving, snorkeling, drift diving, underwater photography, and travel diving.
• High Visibility from a Distance – Bright color design combined with a reflective top strip, printed dive flag pattern, and “DIVER BELOW” text improves surface visibility in open water and low-light conditions.
