Dive Rite SMB - Open Bottom

The Dive Rite Open Bottom SMB is the technical diver's preferred signal tube — the open bottom design allows you to inflate it from your second stage at any depth, making deployment easier and more reliable than closed-bottom models when you're at a deco stop or a safety stop with cold hands and low gas. Once at the surface, it stays inflated and highly visible in bright orange or pink. Required safety kit for any technical, wreck, or open ocean diver.

• Open bottom for easy second-stage inflation at depth
• High-visibility orange or pink for immediate surface identification
• Preferred by technical divers for safe deco stop deployment
• Stays visible even in choppy surface conditions
• Pairs perfectly with a Dive Rite finger spool for controlled ascents
