Consumables are usually extra. Sorb, helium, oxygen and other gas fills, cenote or marine-park entry fees, certification and registration fees, e-learning materials, and equipment or rebreather rental are commonly charged on top of a course price and are not always reflected above. Where a centre states what it excludes, that is noted on the item.

Course names are the centre's own — see their price list. Indicative only; confirm with the centre before booking.
