I stayed at Siladen island (in the Bunaken park) last year and it was great, good guides, great service, nice hotel, food good.

The last one is not a jawfish

nice shots

I saw a very interesting presentation from a Dr (I cannot remember his name for the life of me...US chap...) who had spent a long time researching thermal stress and diving. If memory serves me well, thermal vests have some issues;

 

Turn on the vest just as you get in the water...during the dive your body is warm and on-gassing is aided by this warmth.

 

If its a long dive, how long will the heated vest keep you warm?

 

If your body is chilling at the end of the dive, off-gassing (decompressing) will not be helped.

 

I think the theory goes along the lines of "If you are warm at the beginning of the dive, loading your tissue up with gas is easy but at the end of the dive those chilled tissues may not be so willing to give up their gas"

 

But I can't remember the exact details - I just seem to remember that a heated vest may have some downsides that may not be apparent or obvious.

You got it right! If you are warming (causes vasodilitation) at depth you will on gas more and if cool (causes vasoconstriction)at deco you offgas less. The other post when he switches it off at depth and on at deco will work, but there are no corrections built into deco algorithms for this in todays tables or computers.

I use a pair of Omer ice freediving fins....They are great. You will need a sock as mosrt of these fins can cause rubbing.

Brands to look at Omer, Cressi, Riffe, Esclapez, mares Razor Beuchat, and C4,

Expect to pay over 400 per pair for carbon fiber.

Find a freediving store and try a pair on before purchasing. the foot pockets vary in size and comfort. Look for replaceable blades.

These are all very long fins and will not fit in standard dive bags.Most are around 36" or more long.

curious about the camera/lens combo you used for these great pictures. I am assuming they were taken with your d800.
