  3. 4th dive of the day, I “used” 180 strobe flash’s on the previous dives, of the 450 plus strobe flash’s. I still have 270 flash’s at half power. And probably I will want to reduce the strobe power to allow faster recicle times, which means even more flash triggers. Besides that, usually the 4th dive is a night dive, which means new batteries. Completely agree with the small amount of grease. It is only to get the oring shiny. The grease does not seal. It is there only to avoid the oring to be stressed/damaged due to the friction of the oring with the surfaces it seals against. I do not recommend to put grease on the cap itself. The oring works against the cap but algo against the groove of the oring. The debries/sand/small particles most probably goes inside the oring groove. Putting the grease directly into the oring with the oring inside the groove is not the proper way to minimize risk. In my opinion it increases the risk of leakage.
  4. Inon z240, with envelop batteries has +- 240 flash capacity. Usually I am using my Inon on 50% power (easier to change to other power settings) what makes a capacity of +- 450 flash’s on a full charge of eneloop. Usualy I change the batteries 1 per diving day (3-4 dives), as on average I take 50-60 photos per dive. and when charging the batteries I see that usually I have already 2 or 3 bars lit of 4 bars (totally charged) on the individual battery status of the charger. The exception is if I go for a night dive, them I put a new set of batteries on the strobes, as I use them as dive lamp and I want to grant that I have enough power if something goes wrong. I do not lube the o-ring every time I change battery. It depends on 2 independent factors: - if last dive was in an area with thin sand/mud and I have been close to the bottom, I clean the groove, the cap and wash and lube the o-ring (enough grease to make it shiny). - If unscrewing or screwing the cap I feel it is not smooth Or feel it “grabby”, I do the procedure explained on previous point i do not lube the inner face of the cap because the prong also need to “work” on the oring groove, and lubing the oring directly is the only way to grant that None of the surface will be missing grease and do not cause any malfunction of the oring due to the cap screwing. besides that is the write way to validate if the oring is on proper conditions (no cuts, no debris, etc)
  5. Does anybody uses the product "Silicone Pump from McNett" for care of the button o-rings (as stated on the "Post-Dive Maintenance" section off the article http://www.divephotoguide.com/getting-started-with-underwater-photography/underwater-camera-maintenance/)? How does it compare with the "D&D Top Secret O-Ring Fluid" that Wolfgang uses?
  6. Hi Soaking and pushing several times all the push buttons. Is is critical to grant the flow of the still water through the button grove and the o-ring. Grant the all the air that might be "stucked" in the button groove gets out and still water gets into it.
  7. Another way to use the sun burst is to place it behind a subject to reduce/eliminate/avoid the super bright area that result in a huge brightness range and make it more difficult for the camera to cope with. Of course it is easier with a stationary subject (like a a coral head, an hangover, soft coral, a spirograph) but can also be done with big fish (like a whaleshark, a mantaray, any other big fish, or a fish ball,. You can use also a boat or a canoe. Its a way to place the sun inside but outside the frame .
  8. You said it is a dual cable, so it is connected to only one optical strobe connector in the housing. Do you have another optical strobe connector on the housing to test? It might be a misaligned LED on the optical connector on the housing. But more probably is a cable problem....
  9. Hi. I had several Suunto’s. Always with air integrated. Initially consoles, now wrist computers with wireless air integration. First one was a Suunto Favor Air. Then a Suunto Cobra. My wife started diving, she kept my cobra and I bought a Suunto Vytec DS. And then I decided to offer her a wireless one, She said she likes mine, so I gave her mine and bought the Suunto D9 for me And 2 years ago I was struggling to read the small numbers underwater and decided to sell the D9 and bought a Suunto Vyper Novo. I offered it to my wife and get mine back but she said she wants to keep the Suunto Vytec DS. Regarding another gauge, I do not use it. The decision to go wireless was to reduce the number of hoses. I decided to have all the rig the slim possible. If is loose connection with the tank, I end the dive. All these years I never had a dive aborted due to problems on the connection with the transmitter. Indeed I know some people that struggles a bit with the air transmitter of Suunto, but I think it’s a bit of lack of pacience and not understanding/knowing properly the drill to do the connection.
  10. Hi Clockdive You need to check what is the version of your Z240. The optical sensor shape Type 4 is different from Type 1, 2 and 3. You need to buy the right adapter. For type 1 to 3: http://www.divervision.com/howshot-fiber-adapter-for-inon-strobe-older-slave-sensor-FA-SS2IN.html?search=inon adapter&category_id=64 For type 4: http://www.divervision.com/howshot-fiber-adapter-for-inon-strobes-FA-SS2IN4.html?search=inon adapter&category_id=64 On the label of the strobe it states which version it is.

  11. Hi Julian The mini dome port usually are 100mm diameter (or 4"). Full frame sensors (due to smaller deep of field) usually are more prone to present soft corner on small domes. Mini Dome works well with the cropped sensor and the Tokina 10-17 FE (or other fish eyes for cooped sensor), specially with the extender 1.4. To use it in a Full Frame you need to stop down the aperture to minimize the soft corners, and that might reduce the flexibility to find the right setting for the picture. If you want to do split shots, with the mini dome is not possible (the virtual image inside the dome gets too close and you do not have enough deep of field to have in focus the underwater part and the over-the-water).
  12. Hi Tursiops I accept the critic. The thrush is I never used;/tested a triple clamp underwater. But considering the physics, this configuration should be easy to manouver underwater (or in land). When you open the triple clamp on one handle, only the strobe arm will move (the float one is secured by the other side), the behavior should be more or less like the regular clamp with the strobe arm (slightly less because the clamp won’t be able to move freely) And the focus light does not need a lot of movement. I am not able to test it, as I only have 1 triple clamp (and never used as said before). some days ago I read here an interesting post about someone that is using a “triangle” arm structure as suggested on the scheme for using the strobe with a snoot (instead the focus light) the drawback I see is that the rig gets too bulky, and with a tall structure over the housing, that might bring some difficulties on small spaces. we can not have it all....
  13. If one float arm is not enough, you can use 2, with 3 triple clamps as on the attached schem. if you not have triple clamp but you have an extra regular clamp, you can place the float arm in between the central ball and the focus light
  14. I do not know if the triple clamp with the focus light and the float arm solution is suitable for a regular ULCS arm and stix jumbo, as one end is not blocked (the stick might get loose and be lost during the dive?). But for sure, a float arm is possible. some years ago Aquatica had a float device that was to be used on the central ball, (the same as an floating arm, but more interesting as the fixation was on the middle instead of being in the extremes as the floating arm)
  15. Hi Tim I have an Aquatica housing with aquatica flat port. I have the collar from stix. It works fine. It allows enough space to manouver the manual focus knob. The picture from Gudge is pretty clear about that. The squares on the background shows more than 8 cm free space. You just need place it with the Velcro orientated with the knob. (See also the photo of Algwyn). Sorry I do not have a photo of my system with me. The collar being in the port is really a help exauste it avoids the housing to twist your wrists with the heavy front. (It is not only a matter of the housing being neutral, it is also important to have it with the weights and floats on the write place to avoid being pointing the surface or the seabed) Recently I bought 2 carbon float arms much less expensive than the math you were doing with the arm and the jumbo stix. I had not yet an opportunity to experiment them, but they look very nice! (Around 22€ each) eBay item number: 202812162353 A good thing to have with these float arms (or with the stix) is to have long clamps. Another way I have seen to place the float device was on the point of the focus light. You can use a triple clamp topic there both the focus light and the floating arm. The arm does not need to be fixed on both sides. Some brands also have a hotshoe connector on the flat port and that allow you to put there a ball with a triple clamp for the focus light and the float arm, witchmight help the overall balance of the system with the float being more on the front. Or you can go DIY and fix a ball for that purpose on the front of the port. i really miss diving! BR Pedro Alves
