The Standard Signal Tube is a surface signaling device with its fluorescent orange and neon yellow coloring. 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 & loop straps in a tight roll that will fit in a BCD pocket until needed. Two types of mesh pouches are available to attach your signal tube to your Zeagle BC, as well.
