DPV Cave Course
Certifications available thru NSS-CDS, IANTD and TDI
- This Program is designed to provide
advanced training in cave diving skills to the experienced, certified, responsible
who wishes to conduct dives that warrant DPV use and techniques.
- Expose cave divers to conservation
concerns and ethical responsibilities that present themselves during DPV uses
extended penetration, touring, or exploration.
- Must be qualified as a Cave Diver.
- Must be a minimum of 18 years of
- Have a minimum of 50 logged non
- training cave dives
We will talk about and practice:
- Cave conversation
- Demonstrate perfection of buoyancy and
trim while diving using a DPV.
- Towing procedures
- Swimming with the scooter efficiently
using proper kicks
- Installing a temporary guideline from
a safe exit point
- Matching speed with your dive buddy
- Dropping and recovering the scooter in
the cave to avoid cave impact
- Installing jumps
- On at least one occasion an out of gas
drill will be performed without the donor being aware of whether it is a drill
or real out of gas situation.
- Exit the cave during a simulated zero
visibility situation while avoiding entanglement or loss of the guideline
and maintain team touch contact.
- While using DPVs perform at least 2 towing
methods, at least one of which is while sharing air.
- Simulate a failure of all DPVs in team
and swim the units out of the cave.
- SAC rates and distance/time calculations.
We will gather data regarding your SAC rate and the teams' speed and practice/plan
dead reckoning into the cave so as to plan dives.
- Gas Matching for dissimilar volume cylinders.
- No dives may be conducted to depths greater
than the qualification of the student.
- Oxygen partial pressure may not exceed
1.40 ATA during the working portion of the dives, nor exceed 1.61 ATA during
decompression portion of the dives.
- All dives will be planned using the best
gas in consideration of PO2, END, and Decompression requirements.
- Students who use dive computers must
also carry dive tables as a backup. Divers without a dive computer must use
appropriate dive tables.
- All dives must be completed within both
the oxygen CNS% and OTU limits.
- All appropriate safety or required decompression
stops must be performed.
- Any and all of the above limits not thoroughly
understood by the student will be reviewed in a classroom setting.
You may wonder why the price
is not set like the other classes are set. The fees for this class vary with
the past experience of the diver. If the diver has never piloted a DPV at all
it will take a lot longer for us to get the diver up to speed with thre DPV
than it would, say someone who has been riding DPV's for years and simply needs
the new skills required for cave diving with the DPV. Training standards require
a minimum of 3 training dives. I have found it takes several more unless the
diver is very experienced with the DPV when s/he shows up for class.
