Underwater Alarm / Swimming Glasses

Underwater Alarm
Underwater Alarm

When we swim in the water, In case of emergency,we can't call for help by shouting .The only thing we can do is to struggle in the water. What's more,sometimes there is no strength to struggle at all. And it  may be too late to wait for others to rescue.
The underwater alarm is set on the swimming goggles,when the swimmer press the help button on the goggles,the transmitter will send out the laser of SOS to the water.And then the swimer will receive the rescue immediately.
