In Topic: How did you flood?

I know of one Hugy and one other housing that flooded with sea water despite passing checks.

The corollary of that is that a vacuum leak test is a waste of time!

I used the Hugyfot vacuum system and twice flooded my housings - with air!

Surely the "resistance" was because Hugyfot were forced into inventing the vacuum system when their original redesigned housing mechanism wasn't very good? The current popularity is because vacuum leak detectors have been taken up by some eminent practitioners recently...

... and (recession-led?) paranoia!

I never had a Hugyfot without Hugycheck. It's the reason I chose it!

Nikon RS - faulty design - second dive with it.

Nikon F801 Seacam - hasty assembly after reloading on a boat during my first shark feed.

Fuji S2 Pro - Subal - dome port rotated and fell off as it was handed down to me in the water.

Fuji S2 Pro - Subal - dome port rotated during Zodiac ride but camera/lens saved.

 

Finally changed to negative pressure leak test with Hugyfot (the only manufacturer to offer such a system several years back) and never looked back. Now Nauticam offer such a system I'm sure that there will be less resistance to it on this site.


In Topic: Strobe "Shutter speed"

08 October 2013 - 10:02 AM

The flash makes a burst of light. Its duration is dependent upon the size of the flashtube and the power output of the flash. For example, I have a studio flash at full-power (2000j) that has a long duration of about 1/150 sec. The duration of a little flashtube at low power is very fast indeed. So as long as the pulse of light can fit into the time the camera shutter is open, it will be effective. I suggest it was so dark that the ambient light on the tentacles was so little as to be negliable. (By the way, Bob, I was just thinking I should get rid of my Subtronic strobes too - if they still work!)
