With summer coming quick, the lake is ready to be conquered and a life vest is always a needed item. Instead of that plain-jane orange life vest I think it is time to tech it up this summer with the two-way radio life vest. The vest has a battery-powered, 14-channel two-way radio integrated into the chest. It includes a 1.8-mile signal range and is waterproof (I would certainly hope so) up to a meter deep. For $130 you get the life vest with integrated radio and another spare radio.
