Ice Diving

[Colin]

Even in the summer, I tend to drop like a rock rather than gently lower myself to the bottom, by choice. I found that when I descended in the same manner, my octo tended to start flowing. Can the pressure in the first 5 ft or so change enough that it pushes against the purge valve on the 2nd stage and begins the whole process? *Side note- it seemed that when I went down more gradually, all was right with the world*

Something else to think about....if you are indeed dropping quickly due to being overweighted, then inflating your drysuit with a lot of air to compensate and then at the same time breathing a little heavy will cause the air flow from the first stage to dramatically increase, thereby causing a free flow. Remember, when air expands it cools off......Resetting the IP to a lower pressure may help. But perhaps descending slower and/or dropping some weight may also help.
