Scubapro LiteHawk is nearly identical to the KnightHawk, but doesn't come with weight pockets. It's also about $250 less.

I believe you mentioned the 3CF SA: You can figure consumption on ascent by using the average depth in ATA and multiplying by your consumption rate for that depth. Average depth for an ascent from 133' is about 3ATA. (3 ATA*RMV of 2=6CFM)*4 minutes= 24CF. Sorry if you feel attacked, but I'm...

You'll need to know what your RMV is, to start. Let's assume it's .5 CFM. At 130, you are at 5ATA, so your consumption at that depth is 2.5CFM, assuming you are as relaxed at depth as you were when you determined your SCR to be .5. If something renders your primary gas supply unusable, there is...

ya think? nah....

The bad news is the data presented is virtually worthless for determining risk.

Dude, you asked for quotes and I gave them to you. You can defend all you want, but it's kinda like arguing with yourself. After all, those were your words, not mine, not Bob's,...... See, this is why you have no credibility. That's too bad, cuz a guy with your experience should have a lot of...

Here's what I've noticed: There are many jacket style BCDs which are very bulky. There are many jacket style BCDs which are poorly designed. The vast majority of BP/W divers transitioned from jacket style BCDs. The vast majority of BP/W divers are extremely happy and enthusiastic about...

Thanks Lynne, I use a cattle prod. Okay, not really. If I had a dollar for each time I uttered the phrase "If your knees drop, your ass will follow".... I demo this by getting in trim, then slowly dropping my knees. I show them this the first night while talking about snorkeling. I have vid of...

It really depends on the child and its parental units. I've always made it a policy to interview the child and the parents before taking on kids <14. The thing about diving with kids is their varying degrees of mental and physical inability to assist an adult buddy in many scenarios. There's...

No. This is a vid from August 2010 and features a young student qualifying for Jr. Open Water Diver cert and a 27 yo, healthy and motivated guy. Fitting the kid was a challenge, as he was quite small. Kinda like trying to trim out a neutrally buoyant bowling ball.

Seriously?

Not so much. W was more like those spinning, bouncing fireworks that make vrrrrttttt sounds. IMO, H is more like.... a mosquito that will not die. I think it fed an ego, caused some drama and got some folks worked up for a while, if that's an accomplishment.. I didn't watch that play out in all...

If this isn't a (mis)statement of fact, I don't know what is. Can you provide the supporting evidence? Of course not. Isn't this the sort of thing you've been yammering about? Is this a situation where you hate most in others what you despise most in yourself? Whatever, but imv, I'm pretty sure...

Your compass won't be all that, either.

No, just slightly confused. ;)

Would that be a qualified or unqualified instructor guide?

Have you ever attended a liability seminar for instructors? That cert would be worth a lot if the question of qualifications were ever raised. The bottom line seems to be that you are not qualified (by your own agency standards) to lead the dives you have described. Perhaps a letter to PADI...

You would have an easier task in removing the off color grains of sand from all the beaches of Maui. Personally, I don't accept anything I see posted on the net by users as fact.

I recall the first time I dived my rig in Maui. I believe Stan was the DM and while I was gearing up I noticed him sneering at my rig. I asked what was up and he replied "You techies and your gear" and shook his head. After I asked him to elaborate after the dive, he informed me I didn't need...

Can you give an example where a BP/W would not be appropriate and explain why that would be? It would also be helpful if you could elaborate on your experience diving the BP/W.
