Prebook rental regulators, BCDs, exposure suits, cylinders, and weights, especially in July and August. Send sizes in metric units and ask whether a hood, gloves, boots, computer, SMB, and enriched air are included. Carry certification cards, a log or digital history, and any medical clearance required by the operator. Airlines and rail are easier when the center supplies cylinders and weights. Pack regulators, computers, masks, prescription lenses, and critical exposure items in cabin baggage within airline rules. After diving, rinse thoroughly, dry equipment before moving bases, and contain damp gear in a ventilated or sealed transport bag. Passenger ferries may limit bulky luggage, and public village stairs are a poor place for a full rolling dive case.
