Scuba Sonics - Aqua Maraca Underwater Signaling device - Purple

I like this shaker for its color. However, it's buoyant so it gets in the way at times...

is very comfortable and fits the needs of the diving instructors and novice divers. easy to carry, it is a great product.I use it for my diving and to call the attention of my scuba novices and instructors at the time that requires your attention and be alert of the situation.Thanks for offering!
