Let's not call them limitations, how about unique requirements and conditions?Hank49:I just see it as two different things. Cold water, more equipment is like operating a bulldozer on a hillside. Warm water is driving a car. Each has it's limitations.
I don't think the bulldozer analogy is a particularly good one, but let me try and stretch it for you with a couple of rhetorical questions. Which driver is more skilled, the one that has mastered a car equipped with an automatic transmission, power steering, power brakes and a gas peddle or the driver that can handle two independent drive trains, a manual transmission, manual steering, all on a muddy and slippery slope while operating a giant blade? Who is going to have an easier time transitioning from one vehicle to the other?My point is that training in cold, low viz water won't make you more competent in warm water than one who dives only there just as a bull dozer operator is no better driving a car than say, a traveling salesman.
This isn't universally true, but it's been my experience that in comparing similarly trained and experienced divers, you will find that cold-water divers are significantly better at bouyancy control - they have to be. The great changes in lift at varying depths imposed by 7mm wetsuits or drysuits means that cold water divers have learned to be more sensitive to and more careful about their bouyancy. We grok Boyle's Law. Likewise trim, which is essentially part of the bouyancy issue. Obviously, a cold water diver showing up for a warm water dive is going to need some time to adjust weighting and trim (yeah, I know what we look like on day one of every dive trip), just as the opposite is true. The point is that the conditions the cold water diver is used to have honed his skills at managing the issue to a finer edge, making the transition easier. Though gas consumption is definitely related to conditions, I doubt that conditions have a lot of impact on gas consumption skills.But please, explain what you'll be better at in warm water than a warm water trained diver. Buoancy? Trim? Gas consumption?
Hey, there are few things in this world sweeter than a long, slow, lazy dive on a reef, watching the fishies and contemplating that first apres plongeur beer. One of the few that is higher on my list is dropping down on a 150 year old wooden wreck that is so well preserved there is still rigging attached to the mast. YRMV, but that's what makes the world go 'round.To me, diving in bad vis, cold water would be like climbing a high mountain. You may feel great afterwards because of what you accomplished, but was it fun while you did it? No. More like a hard day's work. But a warm, clear, deep wall.....lots of fish...aahhhhhhh
But, to get back to instructor training: if you're going to teach in cold water, learning to handle all of the extra gear, both yours and your students, that will be required is going to give you a leg up. It's possible to make the switch - people do it all the time - but why set yourself up for a difficult transition if you don't have to? Most of the training agencies take a lot of heat for the quality of the training their students receive, maybe it starts with instructors who decide to take the "easy" way out and short-change themselves on their own training...
