Purchasing diving travel insurance is important for several reasons. First, it provides medical coverage tailored to diving-related accidents, which standard travel insurance may not fully cover. Second, it protects against financial loss if a trip is canceled or interrupted. Third, if your diving equipment is lost, stolen, or damaged, insurance can reimburse you. Fourth, insurance offers emergency assistance and evacuation from remote diving locations. Lastly, it includes non-diving medical coverage, ensuring comprehensive protection during your trip.
