You will need both scuba diving and travel insurance that covers you for the duration of your expedition and for scuba diving up to 30 meters. IF YOU DO NOT HAVE ADEQUATE SCUBA DIVING INSURANCE YOU WILL NOT BE ALLOWED ON THE EXPEDITION.
We strongly recommend you use Divers Alert Network (DAN) for your insurance as they are by far the best and most reasonably priced. Please visit www.diversalertnetwork.org for further details.
