IANTD TEK OPEN WATER DPV DIVER Learn about the advantages of DPV use in technical diving!

IANTD Tek Open Water DPV Diver with Tech Asia

The IANTD Tek Diver Propulsion Vehicle (DPV) Course familiarizes divers with the considerations and skills needed to use DPV’s at high levels of diving. The course outline allows training to be conducted at the technical level to which the diver is already certified.

What Will DPV Diver allow you to do?

With a DPV in hand there are almost no limits to what you might achieve. It can start easily with a fresh look at old dive sites, or perhaps being able to dive somewhere like Puerto Galera's Canyons in the heaviest of conditions with ease. Or maybe to explore where the reef seems to run out, knowing you can comfortably cruise back if there is nothing to be found. Or as tech diver it could be about taking all the effort out of one of our special dives like the Deep Atolls.

In the broader world of tech diving there also comes a point where a DPV becomes an essential item. For example we've used them to video the huge 200m/660ft long wreck of the French liner D'Artagnan at 75m/250ft in the South China Sea, making dives that could never have been accomplished just swimming. Our fleet of Suex XJ-37's has also allowed us to extend a Philippine cave system that we found to a current explored length of 6,062m/19,883ft.  And if you really want to see something cutting edge, look at the video below on this page for a moment...


  • Must be at least 18 years of age, 15 with parental consent.
  • Proof of 25 logged dives.
  • Minimum certification of IANTD Advanced Nitrox or equivalent.

Program Content and Limits

  • Skills will be introduced in confined water and then four open water training dives will be made.
  • These dives must have at least 160 minutes of bottom time and two of them must include at least ten minutes of simulated or real decompression with the DPV.

What You Will Learn

DPV diving will add a whole new dimension to your underwater enjoyment but carries with it some complexities that you need to consider to make it safe and work to your advantage. Beyond the very obvious concerns of ascent and descent rates, you need to learn proper dive technique, think about buddy separation and communication, entanglement with your own equipment as well as what might be in the water, and navigation, so you know where you are going and more importantly, how to get back. Also rare but more serious problems such as what if the DPV floods, stops, or sticks 'on'. A number of things bear thinking about and practicing for.

For techical divers we need to show you how to integrate the DPV into your diving so that it doesn't compromise your basics, like S-Drills and ability to share gas, dealing with SMB's or lines, and handling gas switches safely.

Out of the water you'll also be learning about different types of DPV's, set up, care and maintenance, burn time and dive planning and integrating the DPV effectively into your equipment configuration.

Note: As with other IANTD programs, the diver must complete and pass the written examination, complete all open water requirements efficiently and safely, and meet all criteria on the final Course Evaluation Form in order to be certified.

Equipment, Materials, What's included?

The IANTD DPV course can be taught in whatever equipment you are qualified to be using, be it double or sidemount tanks or even CCR. You will find details of what is included and not included across all IANTD courses on the Overview page.

Use of a Suex XJ-37 DPV is not included in the cost, rental being $45 per dive. A pdf manual is issued upon sign up and payment of a deposit for the course.
