I quit 2 years ago but have been on and off the wagon after about 6 months away from those blasted things. In the caribbean there are a lot of smoking divers and instructors that I've seen. Never seen anyone smoking on the dive boats and I try to be smoke free for several hours before I...

Yup, give everyone plenty of room to have thier own space...when I'm shooting pictures or videos I'm pretty close to solo sometimes. I'm working on that with my 16 year old son who is my best buddy but still needs to focus IMHO...

So you need 14 lbs total? I know that if I have 2 5 lb weights in my non ditchable back pouches I am top heavy and my buoyancy trim changes dramatically...i.e. I can't hover motionless in a helicopter, I tip forward or backward. I had to redistribute the weight keeping the majority in the...

Have you taken any advanced diving certifications or AOW? That's a good way to slow down...PADI has a bunch of classes and specialities...

I agree with the majority...assigned buddy pairs with assignment of a dive leader (the weakest diver) is optimum. Plan the dive and dive the plan... For a trio a similar scenario with a dive leader and a dive plan...suppose someone needs to thumb the dive? What's the plan then? Do all 3...

If you ever get to the Buffalo, NY area check out the Niagara River drift dive = Rocket Man!!

My son and I got OW and AOW from NAUI in the cold water Buffalo NY area. We also have AOW from PADI in the Caribbean. PADI accepted our OW cards without question. Our PADI AOW cards were not accepted by NAUI... The NAUI courses were far more rigorous and demanding as cold water diving is...

I'm looking at backing up our computers with Oceanic Atom 2.0 for a liveaboard vacation next year. My son has the VEO 100Nx and I have been using the PRO Plus 2. We are very happy with them and we'll stick with Oceanic.

So, CriticalMass is correct... pv=nRT => P1/T1=P2/T2 direct proportionality. Do you know anyone with a certified analog test guage with the proper fittings to do the analysis? If you do, do the test, record your results and contact the AI computer manufacturer with your findings. The...

Wait...take any pressure measuring device; hook it up to any pressure vessel with a long hose...now, change the temperature of the gas in the pressure vessel... pv=nRT The pressure will change in direct proportion to the temperature regardless of the temperature of the gas in a vessel with...

I'll back up a lot of the replies so far. I had the same problem during my first few dives. I was very overweighted using at one point 30 lbs in full (7mm farmer john) cold water gear. Now I'm at 24 lbs. I never add any air to my BC after descending even at depths of 60 to 90 ft. In...

I heard Jamaica is out of control with corruption and gang wars which have been crushing the economy for something like 3 years. When we were there in 2007 we didn't even go snorkeling, that's how bad it was even before all the trouble. We did the Rain Forrest Zip Lines...very cool. But...

PADI and NAUI 100 ft for the courses I took.

Hmm...EAN32 at a conservative dose of 1.4...isn't the MOD right around 100 ft? Why push the envelope?

I like the "buddies stay together" rule although my son and I have done it both ways in shallow (20 ft or less) water with full visibility. A couple years ago I was with an instabuddy for a nav course. We were to do a 25 kick cycle square as part of the training exercises. My buddy and I...

I'll second that...:) :popcorn:

Thanks for the info everyone! We'll be doing our first liveaboard to the southern Bahamas next Spring Break. All insight and reviews are greatly appreciated...:popcorn:

Sounds familiar...I live in NY but do most of my diving in the tropics. Guaranteed, my first dive when I come up I find my "winterized" sinuses have been pressure cleaned...into my mask. Remember equalize early and often (with each breath on descent) and periodically equalize your mask with...

That's wonderful!!! Look at that proud Dad!! My son, 16 and I are dive buddies going on 4 years now. Our next trip will be our first liveaboard Spring break...our trips are our Christmases...

Ah, the quarry (30 ft deep mud puddle for us) to Curacao...you'll be doing the ABC's in reverse order then? Next Bonaire...outstanding!!!
