DPV: training.

Training can be very advantageous

I got an SSI DPV card -
we did air shares, tow, push, and some drill where the instructor hung a bunch of weight to the nose of my DPV suddenly
I wouldn't bother unless you need the card to get rentals

Learn the basics off someone using one, just be diligent and do plenty of confined water practise, hell I took mine to the pool a few times on club nights which was very beneficial as you can stop, standup and adjust bits and pieces, on the subject of which, have a good look at how to tie the knot properly on the tow cord, mine originally had it done incorrectly and was causing a real headache as it slipped without myself being aware a few times.

Have fun, start shallow.

Maybe for some. After a brief orientation I was zipping up and over walls, doing inverted flips, and going in and out of narrow swim-thrus with an overhead. Can't see it getting any more complicated than that.

A good tech DPV class is way more than tricks.

A lot of it has to do with logistics and contingency planning, performing S drills while towing, towing dead scooters etc.

A scooter can get you out of trouble but it can also get you into a lot of trouble if you don't plan accordingly.

Like many things, when everything is going fine one doesn't need to know much about how to dive a DPV. In five minutes everyone can do it.

A scooter can get you out of trouble but it can also get you into a lot of trouble if you don't plan accordingly.

I used to start my OW pool sessions with a few steps leading to them swimming around neutrally buoyant in the shallow end of the pool. Then I would tell them that they now knew all they needed to know to dive. The rest of the class was mostly to prepare them for things going wrong.

In the open water, you can have all the fun you want with no problems. It really is pretty easy. But, as Still Kicking says, in more complicated environments, a scooter can get you into very serious trouble, and you need to be prepared.

Really? I wonder why IANTD requires 50 cave dives prior to taking a DPV Cave.

I think mr_v is pointing out that there may be more to safe DPV use, if the prerequisite for even being eligible to enroll in a DPV course (in this case, cave DPV) is so high. 50 cave dives is halfway to your Abe Davis award.

If using DPVs were that simple, surely all new cave divers would be allowed to take the cave DPV class as soon as they were certified at the intro/cave 1 level.

Using it is not difficult, even in a cave At least getting in is easy, getting out through all the silt you stirred up not knowing how to use a DPV is very difficult.

I have seen a lot of DPV divers that know how to propel themselves forward with a DPV, but do not know how to use it correctly. No clue about air sharing while on the trigger, not silting out the enviroment and last but not least emergency procedures like towing.

What does cave diving have to do with any of this?

The original question - the very first post in this thread - was about the differences between recreational and technical DPV usage.

To answer the OP, yes, there is a difference. Cave DPV is a good technical DPV usage example which requires training far beyond being comfortable with the trigger, and in most cases instructors will ask you to be comfortable with a DPV before you sign up for a DPV course.

the Op is history.

Until the next firmware update.
