trim issues caused by buoyant fins

25 April 2014 - 07:42 PM

Guys,
I have a question related to getting my trim right. I currently have scubapro Nova Wings. They are brilliant fins, but have one drawback: They make my feet float, which makes it damn hard to manoeuvre (especially reversing). I'm using neoprene zip boots. I'm looking for a solution to bring buoyancy to neutral or negative. Can anyone give me a suggestion that will help keep my feet from floating up without the use of ankle weights? Are there solutions that allow me to continue to use the nova wings and my booties, or should I be looking into new fins?
I looked at the above and from further research i did online, the scubapro jet max fins, and equivalents are fairly heavy to use. The diverite EXPs seem to be quite stiff, but I have no idea if that's good or bad to be honest. Note that so far I've not been able to locate them where I am (I'm in Shanghai).
I heard the scubapro twin jets are slightly negatively buoyant (but haven't found those locally either). I can get the twin jet max, but I don't know if those are negatively buoyant or not.
Are there any other, more traditional fins, that are neutral or negatively buoyant?

 

PS, I got about size 45 (EU) or 11 (UK). That may limit what fins would be suitable.

 

Thanks!


Stability Issues with setup

12 August 2013 - 10:56 PM

Hi Guys,

I recently got the attached setup for my underwater camera (Olympus camera, Nauticam housing and Z240 strobes).
With this configuration I noticed that the handle bars are quite unstable for this setup. As such I am considering adding a bracket of some sort on the top of the two handle bars above the housing to add stiffness to the construction.
Does anyone know of a bracket for this nauticam setup (the housing and arms are nauticam) that would do the trick? Would I need to make one myself? 

As a secondary question, on land, gravity makes the setup heavy, especially with the strobes apart as in the image. On land this requires the clamps to be tightened quite a bit, to the point that it becomes very hard to adjust the position of the arms. Would this be resolved if I attached the floating arms to the strobes (i.e. swap the arms) making the strobes more floating? Is there another way? (I was told that the dome on this camera makes the housing quite buoyant, which implies that floating arms close to the body is not required, but floating arms close to the strobes may be appreciated...).

Any advice will be appreciated!

Thanks!
K

 

PS the stability problem is very similar to the topic described in the following link, except that the solution cannot be implemented wih hthis housing as it only has one ball mount on the housing, not 2

Using ports for alternative lenses and magic filters

12 July 2013 - 05:49 PM

Hey guys,

 

Finally got my nauticam housing in this week. The port I got for it is the nauticam 6" for the panny 7-14. I don't have the lens yet though and when I tried everything out, I found the 14-42 kit zoom fits perfectly in the port without clipping etc. My question is now, to what extend does it matter that the port is not a prefect match? Why would I get another dome port when the current one can host the 14-42 kit lens with plenty space for diopter filters and other filters is desired?

 

My second question concerns the user of magic filters and potentially combining them with flash. So I haven't used these filters before and as colour correction filters they look very different from standard red or orange filters. How well do they work and what's the drawback of using them with Flash? (Note, I did read their web page)


Resort recommendations Mactan and Panglao

08 July 2013 - 08:47 PM

Hi guys,

Early october I'll be around Cebu for holiday. I plan to dive at Mactan and Panglao, reason for those is because they also have non-dive things to do (I am travelling with a non-diver. I tried to convince her but so far no budging...). Bohol has some nice excursions to the chocolate hills I believe, so that's something that will be done.

Other than that, I hope to dive as much as posisble. I arrive late in the evening, so that day no diving, and probably also no travel to Panglao (too late for ferries), so I'm considering maybe staying a few days in Mactan, then a few days in Panglao, and the last day before my flicht (which is early morning) take a boat back to Mactan for somenon-dive activities and getting rid of N2 gas...

 

Does anyone have any resort/operator recommendations for either location? Mactan seems to be owned by Japanese and Koreans as I could only find japanese and korean websites. For Panglao I heard something about seaquest (their website is down), and Fun Divers.

 

Any suggestions or experiences (good or bad) are welcome!
