    my cootwo let me down

    I replaced the obiwgen sensor and calibrated calibrated O2 I got some 20ppm CO calibration gas and calibrated the CO sensor, as my COOTWO read CAL in the CO display Three days later I flew to Egypt on a LOB Wien I tried to test my. first tank the CO reading read? Replace sensor. Why die IT...

    Walchensee (Germany) - Diver panics at 30m dies, buddies surface too quickly

    You can get an assortment of piston regulators in Austria, the Scubapro MK 25 is very popular My Poseidons are not drysealed either ;) The article does not state whether tecnical problems or the cold environment was culprit. The dive was done with an organization that provides adventure...

    Controlling ascent rates and weighting

    If you really want to enjoy cold water diving, a drysuit is the way to go :-)

    Recreational doubles

    you have to have both tanks of a twinset hydroed which elevates the cost of ownership, all the same I love my Double 8.5l rig for recreational diving :) and might sell my Double 12 because of its weight. not enough deep dives to justify keeping them

    Computer Help..

    It depends how much you want to spend. Shearwater uses great displays, on the other end of the spectrum you can find the Suunto Zoop which is well readable for 1/4 of the price. OLED displays are great but they decay as they become old

    Decompression controversies

    Dr. Marroni from DAN Europe is doing studies in this field. There are bubblers and non-bubblers. Possibly something to do with how much nitric oxide they produce in their endothelium. my conclusion for the time being: If you know you are a bubbler you need to dive far more conservatively than...

    HP steel tanks in cold water

    I dive cold water all year round. Yes, regulators do sometimes freeflow, so what? Avoid inflating your wing/jacket/drysuit when inhaling from the second stage attached to the same first stage as the inflator. As long as the gas in your tank is dry it does not matter how cold the surrounding...

    DAN and Tec Diving

    DAN Europe has completely different conditions compared to DAN America, or DAN Asia. Be careful not to mix the information from different regions. You might want to have a look at Aquamed insurance , too.

    Flooded First Stage

    get yourself a Apeks dust cap, it is waterproof and holds a spare o-ring as a goodie. If you were diving salt water and only noticed after a whole week I would let someone have a look inside. If it was fresh water you should be fine after blowing all the water out.

    Veo 2.0 Conservative Factor Turned On

    CF is meant to account for risk factors the DC cannot know like poor fitness, age, body fat, etc. If you decide to set your VEO 2.0 to higher CF it will pretend you are diving at higher altitude and calculate NDL or deco stops acoording to this setting. You can add conservatism by leaving the...

    Need Help Understanding Bcs

    you description sounds like a so called backinflate BCD. The BCD should only compensate for the weight of the breathing gas you are carrying and the reduced buoyancy of your wetsuit at depth, so it should be rather empty throughout the whole dive. before and after the dive it should offer enough...

    New Diver Looking At Suunto Zoop Or Geo 2.0

    I'd have a look at the Zoop novo, it offers a backlight for the display, useful during night dives. The Suunto RGBM is used by thousands of divers every day, it penalizes short surface intervals and too fast or too slow ascents. Make sure to understand the display in different situations as the...

    Will http://www.ncbi.nlm.nih.gov/pubmed/25525213 change deco procedures?

    If the difference between the profiles is very small - as is likely if you limit the deep stops to 1-3 minutes in a (e.g.) 120 minute (inkluding all deco) dive - you would need a very high number of dives to observe a significant difference in outcome.

    Will http://www.ncbi.nlm.nih.gov/pubmed/25525213 change deco procedures?

    Adjusting the slope via the a/b coefficients should do the trick, should it not?

    Atomic B2 freeflow adjustment

    If I do not know what I am doing, I would refrain from tinkering with vital equipment. I am sure the shop that sold you the regulator will be happy to adjust it for you the way you prefer. slight bubbling with the mouthpiece turned upwards in the water is a sign that the regulator is tuned for...

    Will http://www.ncbi.nlm.nih.gov/pubmed/25525213 change deco procedures?

    What I learnt from the thread on CCRX is that using the common deco models we have a larger risk of DCS on deeper dives than shallower ones using the same model or table. I had assumed they had been adjusted to give long enough deco on deep dives to result in constant DCS probability across all...

    Will http://www.ncbi.nlm.nih.gov/pubmed/25525213 change deco procedures?

    Thank you for the summary. I wonder how to set a DC for the correct gases but honoring the longer time He takes according to this study.
