Franko fish cards and maps are a great way to become familiar with new areas and aquatic life while you are on vacation. They offer dive site and snorkeling information, as well as what kind of aquatic life you will see while venturing. These informative cards are great for kids and adults. Franko Cards are waterproof, laminated plastic, with a hole for a lanyard attachment. So you can take it with you as you swim, snorkel, or dive.
