The TDI cave DPV courses course is program aimed at providing you the tools to execute safe DPV cave dives.

The DPV cave course follows on from the full cave diver training and basic DPV training were you are limited to that of double tanks, Sidemount tanks and the limit of you single rebreather bailout cylinder, training is conducted in full cave equipment, backmount or sidemount or rebreather. It is often combined with stage cave diver as long scooter penetration may require larger reserve gas in the event of emergency.

The TDI DPV cave diver course in not intended to provide instruction for all cave diving environments but is targeted to divers who plan on diving for long duration and or depth a scooter will help to simply enjoy new parts of a cave system, it is highly recommended that the diver has previous decompression diving experience prior to attempting decompression in caves. We can on request combine the TDI decompression Procedures diver program with the DPV cave diver.

At Mexico Underground we run the DPV cave diver over 3 days.

The class fee includes all logistics and training materials, DPV rental
