I feel like it then rotates easier there than in other places but it doesn't feel like it will falls off. Thanks again ! That bare arm is begging you to spend more money! It has the look of a peg-legged pirate. 3

coweyman Posted October 27 Posted October 27 I have a 2 strobe setup and love it. Although I have been looking at doing a 3 ball clamp and adding a video light. It might become to bulky though 1

It might become to bulky though It seems bulky is inescapable. Much like middle-age spread and reading glasses. The three ball clamps work fine, but I also like to use the cold shoes on the housing or port, and fastener bolt holes on some housings.

It will want to float with the LH handle (with both floats) upwards, but there's not much buoyancy in 4 stix floats. 4 large floats is +320gr while the strobe is -150gr. So with 2 on one side it's +170 gr on the left. In the configuration with two floats on each side it's -150+160 = 10gr positive. while the RHS is +160gr a difference of 150 gr more bouyancy on the RH than the LH side. So the unbalance from side to side is very close in both configurations, a difference of 20 grams. On the balls perhaps change all the o-rings to be the same type if they are not already. I would also add that the float each side configuration might need something to keep th floats from floating off the bare of the arm, it's only a push fit as shown in the photo. on a single strobe, should be fine for macro, but probably will struggle for wide angle shots with the mini strobe. Two of them is probably just adequate for WA 2
John E Posted October 27 Posted October 27 Try both arms on one side like the second photo and just have them going over the top of the housing in an arch to keep the Stix floats centred for balance - and then have more range of movement when you take a picture. You may even prefer to only have one handle if you are going as small as possible, eg ditch the right hand one if the handle on the tray doesn't align well with the shutter release on the housing without a shutter release extension. 2

Two of them is probably just adequate for WA These are jumbo floats actually so +726g. So a bit more difference between both config. I'll have a look at the balls thanks ! Didn't realize the orings could be changed. And yes I initially thought about bringing extra clamps to make sure the floats would stay there but I must say that they seem to be really attached. Will check whether I have extra clamps to be sure though. Yep I realize the limitation for the single strobe but had to cut somewhere unfortunately. It is already much heavier / bigger than I wish already. Thinking of doing mainly WA close to the surface without any strobe and use the strobe for macro. 7 minutes ago, John E said: Try both arms on one side like the second photo and just have them going over the top of the housing in an arch to keep the Stix floats centred for balance - and then have more range of movement when you take a picture.

Ah nice idea, I will try that ! Also thought of getting rid of one arm but didn't want to risk hating it so took both with me. After a few dive, I will try removing one and see how it goes. Do you usually handle the strobe with the left hand or is that a personal preference thing ? 1

Didn't realize the orings could be changed. For the 1" balls on Ultralight Control System hardware, they recommend Buna O Rings size 2-209, or Danco #95 15/16 x 11/16 x 1/8 inches. (I really prefer metric measurements). 1
John E Posted October 28 Posted October 28 Sound like you have it sorted. Having one handle is a personal preference and what fits the particular housing, especially for a generic housing that may have a handle a little bit too far from the shutter release. Like you are doing ... easiest to just have two to start then see what you like. 2
Floris Bennema Posted October 29 Posted October 29 I prefer a hand strap on the side of the shutter release. Not sure if it's possible on a AIO housing. 2
