Had a great time today with Jess. Anyone who needs a dive buddy ... Jess is your man. Very fun to hang out with and a very safe/knowledgeable diver.
Our first dive went down to 121' for about 5 minutes, then we worked our way up to 80 for 10, then 40 for 10 and finally 20/10/5 and out. We were down a little over 30 minutes for that dive.
Our second dive was only down to about 70' with a gradual descent then back up to 40 for about 10 minutes than 20ish and finally 5.
We hit some of the outcroppings and as our exhaust gas rose it became trapped under one of the outcroppings creating a large bubble. Being a noob that was interesting to me, so I just kinda created a larger air pocket there intending to just swim on on away afterwards. As I started to move away Jess motioned for me to look at the top side of the rock formation. What was cool was that the air in our newly formed pocket then rose up through the sedentary rock formations and bubbled on up to the surface. It was neat to see several bubble trails rise up like that. We went on and had a leisurely dive afterwards.
At 5 feet I still had about 700 psi left and wanted do do a Mythbuster style check on the uncontrolled ascent theory of dbl al80's with my 3ml farmer john at equal to or less than 500psi at 15ffw. I used my secondary to purge my dbl's down to 500psi and was still neg & hovered just fine. Purged some more down to 300 psi ... again same result. Now, I'm only using a 6lb ss bp with no weight belt so I was surprised that at 0psi I was still not going pos like so many told me I would. I could still hover or descend if I wanted so myth busted ... no runaway ascent in freshwater with dbl al80's in a full 3ml farmer-john wet-suit at 500psi or even 0psi. At 0psi in 5ffw I could still hover.
Fortunately Jess had me surface so that I didn't get my tanks so far empty that they'd take on water. Thanks for that one Jess.
I enjoyed this day very much
