Hi guys. I've just done AOW in Tobago and thought I would post a short report since there are regular questions asked about AOW.

First, I am glad I waited a short time between getting OW and doing AOW. Simpy because I already felt comfortable with a few dives under my belt so that I could focus on the specific dives I was doing rather than still on the basics.

Deep dive and underwater navigation are compulsory. The deep dive was at a site where there is the wreck of the Maverick. It is a small ro-ro ferry sunk deliberately in 1997 and lying in 30m of water. This was the dive I was most apprehensive about but it felt great. We descended a permanent line and gradually the hull came into view. We swam round about it, through it and then along the bottom car deck. It was also my first wreck dive and I think I could get a new interest! BT was 30 minutes, water temp 28 degrees, conditions pretty calm. All in all, a nice way to start.

Navigation I did at a sandy area just off Kariwak reef. It was pretty uneventful. I did all the routines (had to do the square twice because I made a mess first time!)

As my 3 other dives, I chose drift, peak performance buoyancy and wreck. The wreck was at the site of a broken up wreck called Dutchman's Wreck at Mount Irvine Bay - there were a few canons in the surrounding reef but not much more. Again water was 28 degrees, calm and vis around 15-20m. BT 45 minutes.

Drift was a cool dive at a site called Flying Reef. There was a reasonable current without it being too strong - though you did feel its strength when you tried to go against it, which took some exertion. It was great just floating along. I could get into that, too.

The PPB exercises we did again at Kariwak and then had a nice tour of the reef. I enjoyed trying to perfect neutral buoyancy orally inflating the BCD. Kept putting in a bit too much air at first, then I got it.

I did the course with Undersea Tobago based at the Coco Reef hotel. It's a pretty good set up. All were boat dives, the longest trip being the Maverick and other wreck sites (maybe 30 minutes).

I'm glad I've done the course and now aim to get a lot more dives in and then maybe think about Rescue Diver in due course. I'll post something on Tobago in the travel forum in due course.

PS - I should have said, I bought the course book before I left and did all the knowledge reviews so that I wouldn't have too much time reading and writing in Tobago.
 
Congrats!

I will be doing my AOW mixed in with Nitrox in two weeks, can't wait. I will be heading down to Roatan (BIBR) for what I hope to be some very excellent diving.

My GF and I are very excited about this chance to add to our skill set.

I will post a trip report when I return :)

This is a deco dive on the Naui tables, requiring a 5 min stop at 15 ft. as far as I can tell...(was looking at the tables Naui has on the web)

I haven't had the opportunity to look at the other two sets of tables I have.
 
The PADI tables are even more conservative: 20 min NDL at 100 ft = 30 meters. The 10 minutes over sets you up for a 15 minute safety stop, gas permitting. Granted, my PADI tables are written for a 60 ft/min ascent rate (18meters/min).

Brizzolatti, I wonder if you could talk a little bit more about what you did during the peak performance buoyancy dive? You mentioned oral inflation of the BC? I thought that you did that as an emergency measure when your power inflator fails. One instructor told me that the way she does it is to make you go through a bunch of depth changes without touching your BC inflate/deflate. I'm curious as to how yours was taught.

Thanks,
 
my peak perf. bouyancy class for AOW was a pool session where we worked out weighting, and then I was put through a scuba obstacle course of sorts....

Once we were satisfied I could operate properly, stop at most any depth I wanted, etc., we went to the ocean for two dives where we did more work....

I still need to practice and get better, but I'm better than I was before the classes.
 
Hi, Greg. Re the oral inflation, before the dive the instructor went through all the routines we were going to be doing (hovering, fin pivots etc etc) and explained also that we would try the oral inflation of the BCD. He demonstrated how to do it and I practised on land. Once we were into the dive and I'd done the regular exercises, we did the oral inflation exercise. Basically, I used power inflator and then did the oral bit to fine tune and refine. It wasn't presented as the standard way to get neutral but as a different mechanism. Just an additional skill.
