    What too buy?

    Yes, they have definitely confirmed the access to manual white balance. Unfortunately, this was about all I could get out of them for now as I guess everything is in its very early stages!! They have now told me that a preview to the housing will be available on their site within the next 10...

    What too buy?

    I sympathise! I have been researching for around 2 months as to exactly what to go for, but this forum has acted as an excellent source of information - being extremely new to this field the only real tip I can give you now is to learn as much as possible about the different types of technology...

    Housings offering white balance access

    Fantastic, thanks for all this information. I have read some more reviews regarding the camera and as you say it looks very impressive! One more quick question (if you dont mind!!) when you say "You must get the upgrades though (wide angle lens, manual controls).". I have looked at the...

    Housings offering white balance access

    Exellent site and I have just spend too much time looking at the images when i should be working :-). Just a couple quick questions. Does the housing let you switch to stills? I notice the panasonic takes 4 megapixel stills as well and the ability to switch to still mode would be a major...

    Nitrogen bubbles and air bubbles

    Exellent, this is really helping, thanks. Just a couple more questions. You say that: "regular bubbles in the blood from improper decompression almost exclusively form in the venous system" Why is this? And in what situation can they form outside of the Venous system? Thanks again for...

    Nitrogen bubbles and air bubbles

    So... Its more that Nitrogen bubbles will restrict the flow of blood to the brain and other vital tissues, where as Air bubbles will travel to the brain? I.E If someone was injected with gas in the arm...(this is a pleasent conversation :-) ) Thanks, tristan

    Help with RDP Question please !

    Am I right in thinking here that if the residual nitrogen level added to the bottom time puts you in the black when you calculate the next depth then you should use a more conservative figure? As that obviously makes the answer above wrong. As the second dive puts you in the black... Thanks...

    Help with RDP Question please !

    Exellent, thanks for that. An anoying thing is that on my RDP the surface interval between the X and the T is 13:15 not the 12 that you mentioned, which was putting me out each time (I now discover). Is this common ? To be honest im using a RDP printed on the back of my log book so it may not be...
