A Snorkel Guide or Instructor typically starts their day by preparing equipment, conducting safety briefings, and overseeing group fits for masks, fins, and snorkels. Throughout the excursion, they monitor participants in the water, provide basic instruction, identify interesting marine life, and respond to any safety concerns. Guides also maintain equipment and record tour details after each trip. Working closely with other guides and boat crew members, they ensure a safe and enjoyable experience for all guests.
