Most of us never look at a first-aid kit until there’s an emergency. If you’re planning an extended cruise to remote areas, include the HallMEDpac Medic on your must-have list. This is a hospital and a pharmacy rolled into one and packed in a waterproof case. With it you can treat jellyfish stings, a laceration, an infected wound, and myriad other ailments. It includes oxygen with a regulator, pain medications, plasters, sutures, and other items you may be glad to have onboard.
