    Question regarding tank fills

    Sorry that this post seems to have devolved into a measuring contest. Please remember that the original question in Post #53 was “why aren't 3AL tanks as tolerant of overfilling as 3AA tanks?” and in Post #56 “It is my contention that those differences in properties were taken into...

    Question regarding tank fills

    Anecdotal evidence does not convince anyone of the validity of your arguments.

    Question regarding tank fills

    This does not answer my question. Neither does your video. I am pretty sure that shooting high caliber ammunition at scuba tanks does not certify tank integrity. We have already agreed with this statement. If you believe this to be the main difference between steel and aluminum, you must...

    NAUI since 1989 needs new card

    I just tried this and it worked. Several years ago I tried to locate my certs on the NAUI site. They weren't all there. Come to find out, some of my certs had my middle initial on them and some did not. Evidently, the search engine at NAUI is very specific when it comes to looking up your...

    Question regarding tank fills

    I very well could be wrong. I often am. I am just asking for a good reference that states that it is OK to overfill steel 3AA and not to overfill 3AL. The only links provided so far have been anecdotal evidence. As I said, "I am not in favor of significantly overfilling any tank; but, why...

    Question regarding tank fills

    Agreed - - The use of Aluminum alloy 6351 certainly has given the aluminum tank (3AL) a bad rap.

    Question regarding tank fills

    I am not quite sure this statement is true. Keep in mind that the question was "why aren't 3AL tanks as tolerant of overfilling as 3AA tanks?" You're generalized response does not address those two specifications. Steel and aluminum are different materials with different properties. It is my...

    My turn just came up a few weeks ago. This was my second Freedom Plate. My grandson commandeered my first one. Be patient, it's worth the wait.

    Need a Training Recommendation

    This past summer, our daughter-in-law decided to try a scuba dive while we were on vacation in Cozumel. Best Dive Ever She is the one on the right. After the dives, I promised that I would find her an instructor so that she could have a full certification next year. Since then, that part of...

    Southwest To Cozumel

    Just for fun, and from Houston, I selected a 3/10 departure and a 3/17 return. Grand total round trip at 'Wanna Get Away' pricing - $425.38. Outstanding. The cost recap on the final page, however, listed the flights at $164 round trip plus $261.38 in taxes and fees. Amazing that taxes and...

    Best Dive Ever

    We just got back from Cozumel. Stayed at the Occidental Grand and dived with ProDive. The entire family, all twelve of us, spent eight days diving, beach sitting, and dining in what had to have been the "Best Vacation Ever". On Thursday, as an early father's day, our three sons hired a...

    Insta-buddy DECO Diver: What’s NDL?

    Thanks, that is the signal that I see used most during any dive briefing. It's just that when I was trained, we did not have any SPGs and thus did not have a corresponding sign. We also used American Sign Language for communication of numbers - that, too, seems to be different today...

    Insta-buddy DECO Diver: What’s NDL?

    As long as we are being honest, a signal for "what's your pressure?" was not covered in my training.

    Scuba Cylinder kills fire fighter

    Looking at photo on page 9 in the link that @rjack321 placed in post #42, it does appear that the valve was sheared when it struck the wall.

    Question about air integrated computers and transmitters

    When I started diving, there were no pressure gauges. We were meticulous about planning our dives so that we could always count on having sufficient air to complete the dive. Along comes the SPG - what a great addition. We were now able to know how much air we had left at any time. Single...

    What is the "normal" cost for the Nitrox class?

    I received my Nitrox training and card from the principle author of the NAUI nitrox manual. This was several years ago, but the training, including the card, was only $75. I do not think that I "cheaped out" on this. I truly think that I sought out and received some of the best instruction...

    What is the "normal" cost for the Nitrox class?

    When getting EAx certs for my family, I searched the lowest cost I could find. I was pretty intrigued with this company - B & W Dive Co. - but they were on the other side of town and I found a local, independent instructor that would accommodate this training for about the same price.
