In Topic: How did you flood?

27 December 2013 - 11:15 AM

Two Major floods  Ikelite Housings D70 first when I was ignorant and starting with DSLR  Port oring poorly seated.

Second D300 Ikelite Longest port with Sigma105 in a current holding line on surface think it banged on something and was nearly full at 5M.

 

Also a self serviced G1 Ikelite housing (checked without camera) failed to seat most button orings water poured in so fast I had to do it again to see which ones were leaking (no electronics in that housing).

 

Now I have Bill's (Underwater Camera Stuff) vacuum checker no leaks but two false alarms from the electronics probably due to temperature change (I now vac the housing to about 1 psi over where it goes green, that seems to be enough). AND one genuine warning of a poorly seated oring that would have drowned camera. So I'm definitely ahead on that.  Although this showed up when failing to pressurise at all so electronics not needed on that occasion. But I like the green flashing lights!


In Topic: Housing rinsing techniques

19 October 2013 - 02:13 AM

I use an Ikelite rig, my concerns re salt crystals are solely in the push buttons. Salt water gets trapped in these and only dries slowly and may take a week out of water to become supersaturated and start to crystalize, I believe it is vital to remove all salt from within button holes before prolonged storage (more than a couple of days). Therefore:-

 I may dunk after a dive but don't obsess about it, at the end of a trip before flying home I will get a tank of fresh clean water and reassemble housing without camera and repeatedly press buttons and use an air nozzle from my reg to dry out water before dunk and button press again. Repeat thrice.

In Topic: New Housing "Airlock" Vacuum from Backscatter

09 March 2013 - 07:00 AM

Just found this thread and pleased to see that for once I'm ahead of the pack. I just fitted and used on a trip to the Northern Red Sea, a Housing Sentry from Bill Libecap. This is a two part electronic version, Bill kindly tailored a valve assembly for me to fit in the threaded housing hole of my Ikelite D300s housing. Now I know that Ikelite are not the most ergonomic housings, I try to set the camera up as far as possible and not alter settings underwater, and so I seldom if ever use the control for DOF and the F button on the D300s also the push rod used for those controls is the single thing making camera installation difficult so it was obvious to me that sacrificing this control was a minimum risk installation strategy. It took about an hour to install worked first time and has given a huge increase in confidence in use after a serious flood 3months ago. This flood was not I think user error but occurred in a fast current on the surface while descending a shot line, I believe the long macro  port attached got knocked and the current flow forced water past the oring that on the surface was not pressure sealed. The vacuum device should and has on 18 dives so far prevented a flood this has included backward roll RIB entries and occasional giant stride of the back deck.

 Re releasing vacuum and opening housing causing a few drops of water to enter, yes I have noted this and it is important to rinse and dry the outside prior to opening but not a major problem.

 I would echo the sentiments about Bill being easy to work with and get what you want to install in your camera, thanks Bill
