#345569 Vacuum leak detector question

Posted by Draq on 03 April 2014 - 05:14 AM

Obviously this needs some extensive testing.  I suggest we send a dedicated and unbiased researcher (that would be me) to the Caribbean for a grueling two-week regimen of test dives.  I will thoroughly document the testing process and advise you of the results upon my return home.  In regard to funding this research, please send a PM and I will send you my paypal address. 


Now about this Scotch Mist; does adding lemon peel to a nice whisky really create an enjoyable beverage?  I have my doubts but could probably experiment with that as well during the above two-week research project.  No additional funding would be required for this.  Plus, I could watch for condensation on my glass as I go from an air-conditioned room to the patio and supplement the fogging data.

Sorry about that Draq!  



No worries, I am fine.  I am still inclined to think the vacuum offers some added seal at the surface but there clearly is a difference of opinion on that.  It doesn't change anything for me either way, so I am perfectly content watching you more science-oriented types duke it out.  Nothing much to watch on television lately anyway.  :D

It's a good thing we got a separate mirrorless forum for such engaging topics.

In my defense, it started out as a discussion about The Nauti vacuum system on a mirrorless housing, but it has kind of taken on a life of its own    :island:

I didn't mean to cause controversy...


FWIW, I already decided to get the vacuum installed for its intended benefit and don't plan on treating the housing differently than before.  I try to have the housing handed down to me from a boat. I was just wondering if there was any valid reason to believe a leak was less likely due to the vacuum at times when the housing is not otherwise under pressure.  Curiosity more than any sort of buying decision.  I am not really concerned about a cracked port or viewfinder.  I see those as fairly unlikely for me and I suspect with or without the vacuum, such damage would most likely mean game over.

I am not sure you will get a lot of responses on this thread.  FWIW, it is my opinion that the 14-45 is a slightly superior lens than the 14-42 but for underwater use, the differences would be minimal.  Either is okay as a general purpose lens, and you can do decent macro with either lens and an adapter and close up lens, but neither is ideal for macro or wide angle.  I would suggest deciding which you think is of more appeal (wide angle shots, including close focus wide angle, or macro shots of small things.  If the former, look at getting a 7-14, 9-18 or 12mm lens, or my favorite, the 8mm fisheye.  If macro, then get the 45 or 60mm macro lenses available for your system.  If money is tight, you can do decent macro with what you have now, so I would look at a wide angle lens (unless wide angle is just not your interest.  You will need to add a strobe fairly soon as well, although you can do a fair bit of natural light wide angle.


I would make this suggestion, though:  Wait until you have been diving for awhile before dealing with the photography.  Carrying a camera around complicates buoyancy and task loading at a time when you need to be focusing on diving skills. When you are feeling quite comfortable with your diving skills, then add a camera into the mix.  For some this happens fairly fast; for some it takes awhile.


Now a shameless plug:  I have a housing and ports for the GF-1 for sale in the classifieds and would be happy to make you a good deal on some or all of what I am selling.
