    Yes. We encourage all of our customers to have valid dive insurance when diving with us. Although scuba diving is considered a safe activity, in the unfortunate event of a diving accident, even a minor one, insurance payouts can run into hundreds of thousands of US dollars, and standard health insurance will not pay for diving related expenses. We are partnered with DAN dive insurance and we encourage our customers to purchase a plan through their site here: For as little as $40USD you will be covered for one year, a small cost for a big piece of mind.
