How much do the Sentinel consumables cost?
As with all rebreathers, the major consumable cost is CO2 absorbent and the Sentinel can use several different forms of absorbent. The cost of absorbent will vary depending on variety of factors, but the range is from $20 to $30 per single load. A load typically can be used for several dives, but there are also other smaller costs such as gas fills. Keep in mind that for both open-circuit and rebreather divers, consumables costs are usually insignificant in relationship to the investment in the equipment, training and other diving costs such as boat charters and travel.
