In general can all equipment be borrowed at dive centres we are visiting. However we do recommend to bring your own dive-computer (with full charged battery), mask, suit, shoes/gloves, knife and (maybe) fins. Everything else (BCD, regulator, etc.) should without hesitation be borrowed at the dive centres. This has the advantage of fewer luggage items to be carried. Not forgetting that tech-equipment is highly maintained at the dive centres. This is of course an advantage.
However, feel free to bring your own equipment if desired.
