Typically, going out on the open sea for the day nobody stops and thinks, “Wait, what about my camera/phone/electronic device?” A day on the boat or a day at the beach means never toting anything that would react negatively with the ocean, like a cell phone. But that could cause issues; cell phones are a communication tool that may be necessary in an emergency, for those who don’t have PLBs or EPIRBs. They vital for communicating location, meet ups, etc. Having a cover of some sort that prevents and protects an electronic device is not only an inexpensive option (in contrast to replacing a smart phone completely, warranties don’t cover water damage) but one that will prevent loss of data and stress, waterproof containers & cases.
Electronics and items that you should consider purchasing cases for: your smart phone or iPhone, camera, mp3 player, identification cards, credit cards, business cards, money, food, your GPS, etc. There are many different kinds of brands that sell these high quality water resistant waterproof containers and cases like Otterbox, Drypak, Pelican, and more. It’s difficult to avoid the water when you’re out on it, so plan ahead and purchase a case or container that will safekeep your valuables against water damage.
