Once it is programmed into your radio, you will be able to provide emergency services with information like emergency contacts, color/make/model of your boat, and your personal information to help aid them. We highly recommend making full use of this feature to keep you and your family safe on the water! 🌊 🌊 🌊 🌊 🌊 🌊 🌊 🌊 🌊 #atlanticmarine #gradywhiteboats #gradywhite #wilmingtonnc #topsa
