Abstract: An underwater communication device in combination with a chemiluminescent glow stick. The combination comprises a rigid housing having a seat structure for receiving a chemiluminescent glow stick on an outer face of the housing and a loop structure on a second outer face of the housing for attachment to another object. A projectile resides within the rigid housing such that movement of the housing will cause the projectile to move within the housing impacting an inner surface of the housing causing sound vibrations. A chemiluminescent glow stick is engaged with the seat structure, illumination of the glow stick providing means for visual underwater communication. A means for maintaining engagement of the glow stick with the seat structure of the rigid housing maintains the glow stick against the seat structure.
