Yes, but it's not the capacitor per se that you hear. To make the very high voltage that a flash needs from a 1.5 or 3 volt battery, the flash apparatus incorporates a DC to DC conversion and a charge pump which stores the high voltage in the capacitor. This has an AC intermediate step, which is that ascending high frequency whine that you hear when it's charging up. Whether or not a shark might find that interesting is a question for someone else.doesn't the capacitor have to charge to produce a flash?

That would explain a lot.
Did they intentionally leave out the footage that would show them feeding them?
Again though, these videos do nothing to defend against my point of how this 'dive site' is like the wild west with everybody doing whatever they want in the name of making a fast buck.
If 2 are feeding regularly and 20 are not what is the end result?
Can anyone tell if this is a feeding dive?

These sharks are not keeping the distance that I would consider natural for sharks either.
So learning that keeping the stick vertical is interesting. I don't suppose you have a picture of your PVC stick? Mine was about 2ft long, and maybe 1/2 inch wide.
Just another observation and one of the main reasons why I question the rational of blindly believing since nothing has happened, nothing will happen on these dives...
The one common factor in every one of these sightings is everyone of them has been at a great distance. I can't think of any shark (beyond a nurse shark) or a 'tame' shark from a feeding dive, that I have witnessed that didn't keep it's distance. Most of these sightings involve seeing one so far away you wish you were closer.
