i will reply in her stead to some of the above saturaton , and thank you for the attention as well. neither of us are in the greatest shape of our lives , but far from debilitated , for her first dive yes she wore a weight belt , 2nd dive was on my weight integrated bc(i went with a vintage backpack and a weight belt) . yes she said the weight belt wasnt sitting confortably on her (hence the switch) , both dives of the day were single tank dives , both 40 minutes long , both with a max depth of 35 feet . i technically did 3 dives that day ( my first was a contour out to 35 feet to set the buoy and a slow ascent along the buoy line). the first dive for us both was a contour dive starting in 5 feet of water , and a slow ascent along the buoy line (me reeling it up as we ascended) the second dive for us both (after a 1.5 hour SI) was a contour dive from 5 feet out to 35 feet , a 5 minute hold there , and the remainder following the contour of the shoreline in progressivly shallower patterns ending with a final ascent from 8 feet. i am highly doubting DCI in regards to our profile (and the consideration of our similar lifestyle and health status and the fact that i made one more dive than her with no signs of DCI) and the fact that she did begin her period late the next day. that being said I am glad she followed through with contacting DAN and will be seeing her doctor for a referral ASAP , im not a professional and even though everything in me says silly coincidence , theres the voice of my old instructer in the back of my head saying simply to check it out and be safe. on behalf of myself and her as well thank you all for your input on this folks, and although we will probably never meet most of you in person , i do hope you do not consider us clueless divers , or dangerous divers. she and i just wish to be extra careful with anything either of us feels is not quite right.
