A must-have for any serious diver, the Zeagle Signal Tube (SMB) is a surface signaling device with its fluorescent orange and neon yellow colouring. The tube is inflated at the surface with an oral inflation valve and measures 6” x 60” for maximum visibility in choppy waters. Zeagle Signal Tubes roll up and fasten with hook and loop straps in a tight roll that will fit in a BCD pocket until needed.

This SMB is only intended to be inflated at the surface, since it does not have an overpressure relief valve. If you would like to deploy from depth, select the Zeagle Deluxe Signal Tube (DSMB).
