My idea is to create a wristband device that monitors young swimmers.  If the swimmer gets into trouble, the device alerts the parent, carer, and anyone nearby to ensure immediate action is taken. 

The problem this GI venture solves is drownings due to parents and carers not being aware that young swimmers are in trouble.

This GI venture, Swim Safe, is a wristband that sends notifications, firstly to a dedicated mobile app, and secondly, as a Bluetooth notification, to any nearby devices.
