ABSTRACT:
The apparatus of the present invention has a shell, an indicator and straps. The shell has flanges at the top and bottom, respectively, constricting the hole size at the ends of the shell. The shell can be comprised of a body and a cap. The indicator is in telescoping engagement with the shell. The indicator has two ends. The first end of the indicator protrudes from the second end of the shell. A weight is at the second end of the indicator. The weight has a sidewall with an outer periphery greater in size than the inner periphery of the shell ends. The straps are used to secure the apparatus to a person. The indicator extends from the shell when the person enters the water. The indicator, aided by the weight, retracts into the shell when the person exits the water. The shell can have wings.
