    Gas planning and the associated math - controversies over need and how to teach

    Most divers don't pursue MD or deco certs. Gas planning needs to be introduced as soon as possible and it need not be confusing if presented properly. 1/2 out, 1/2 back isn't a plan, it's a recipe for disaster. While the concept of gas planning in relation to dive planning is a new concept...

    Hover problems

    Not too likely, but I suppose it's possible. Absolutely.

    Hover problems

    I'm referring to a BC which has the bladder in the back. A wing would be an example of back inflate, but many jackets are also back inflate, the Black Diamond, for example. Three things can affect your trim, AFAIK... Ballast, buoyancy and energy. It sounds like your ballast is balanced, so I'm...

    Encourage me as I learn to dive

    Just to be sure I understand, pool session one was conducted in a hot tub? As to the snorkel/inflator issue, the inflator hose should be retained by a velcro strap, which is typically a bit above nipple level. Your snorkel shouldn't be riding that low, so if you develop muscle memory to start...

    How would you teach a 10yr old to use dive tables?

    There's a lot of different methods you could use. The most effective will depend on your kid. The first thing I teach kids is that they already use tables. Anyone who can follow a multiplication table can work the tables, which is the good news. The bad news is that a simple error can result in...

    Jeffg is the first that comes to mind. Guess you could say he helped me to help myself and that's a gift that keeps giving.

    Over the head donning of BC

    With the exception of the long hose, my gear is no more complicated than it was in 1978. Tank, first stage, second stage, secondary second stage, pressure gauge, BP/W. Nothing more, nothing less. What complications are you referring to?

    Where did you dive today?

    A little late to report, but did the Black Water Night Dive on the Big Island last Wednesday. Bottom was somewhere deeper than 7000' and my max depth was a bit over 50'. We splashed at about 22:30 and spent :50 seeing things I never knew existed.

    I learned that cameras are easier to lose than they are to find.

    uncontrolled finning ascent

    If you're neutral when still, you must be directing your thrust downward. There are only three things which can cause you to ascend: thrust, buoyancy or water movement.

    Documentary on solo diving

    Heya venuss, Yes, you read that exactly right. I wouldn't say that's the only time I carry redundant gas, but I don't typically carry RG on dives shallower than 80'.

    Transition from pool to OW

    My first time on SCUBA was in OW, so I can't really speak from personal experience on this, but....... As a DC, the biggest issue I saw in the transition was getting used to the rubber... Gloves and hoods being the biggest issue. From the 87 degree pool with no exposure protection to a 7mil...
