Due to my prior dive habits and preferences, I prefer to pull my last deco stop at 20 feet, not 10 feet. Then, I take about five or six minutes to go from 20 feet to the surface after the completion of this 20 foot stop. I don't like the last stop being at 10 because this can allow for unacceptably large depth changes in rougher seas when waves pass overhead, and it can get pretty rough at this depth as compared to making the last stop at 20 feet.
With my Hammerhead, it keeps calling for 10 foot stops. Even if I pull longer stops at 20, my required 10 foot stop time does not seem get reduced on the handset. Does anyone have a solution for this? What are you doing?
It would be great if the user could set the last stop depth on the unit.
The HH will clear 10fsw stops at 20 fsw no problems, its just longer than you expect (its the way the HH projects the ascent).. If you run the math, on a gf profile with the endpoint being 10fsw, it requires a longer than the 10fsw listed to clear because of the difference in the way the allowable gf is calculaed (its based on current depth) (and loop content).. The lower the po2 is at 20fsw the longer it will take to clear.. if you keep the po2 at 20fsw between 1.4 and 1.5 it clears reasonably well., better yet.. after you clear your 20fsw time, just ascend a few feet (say to 15-18 fsw) the time will count off more quickly than if you were at 20-22fsw (again its how it predicts the ascent, the key is to above the previous stop depth (in meters))..
The higher you have the conservatism set (lower the gf-high) th slower you will see the time tick off..
