In Topic: Aquatica Vacuum Leak Sensor turns orange underwater

I have the exact same setup, but during the initial pump down stage, I do a couple to three more pumps after the LED has turned green. I've taken the system down to recreational scuba limits with no change in LED colour.  Also, I wouldn't suggest leaving the system pumped down as it would accelerate battery consumption.   





In Topic: Yet another DIY fibresnoot

I make my own snoots for the D1 and now making a set for a friend's Z240.  The light on the D1 isn't bright enough to aim with, especially if you're looking at piggy backing it onto the main light.  I saw that someone sells a laser that you can mount on the arm to help aim them, I think it was 10-Bar.



In Topic: which setup to shoot burst underwater?

11 August 2015 - 08:38 AM

I have shot higher speed bursts underwater.  I used my 5dmk3 shooting at 6fps with the YS-D1's.  By default, as the 5dmk3 does not have a pop up flash, I used electrical sync cords.  I used this set up mainly for mandarin fish or anemone fish shots.  Using the D1's at 1 click under half power, sometimes even 2 clicks.  I find I can fire around a 2 second burst with the D1's.  I don't do this often and do let the strobes cool down. Most of the time the burst is for 6-8 shots.   


Optical triggering by the factory popup flash won't usually work even if you manually set the flash to low power as (in Canon's case) the body limits to 3fps.  If you want optical triggering then you'll need some sort of converter from electrical to optical, like the one found on S&S housings, I believe this setup will also do TTL, but I don't have first hand experience.

After the vinegar, rinse out with fresh water then 99% rubbing alcohol.   The alcohol should displace the any leftover water and dry with no residue.
