Altitude diving with Hammer Head

SkinAndScuba · 25th November 2007, 20:45

The Hammer Head does not take altitude into consideration when calculating deco obligations. How are divers diving at altitude getting around this?

I often dive in a quarry that sits at 750 meters or so, it's not a huge difference in pressure from sea level but I don't follow the HH deco.
I usually use v-panner (that allows elevation data input) to plan my decompression dives there.
Best,

Zé.

Unfortunately my altitude diving is mostly mutiple level profile. I also use V-Planner to plan some of my dives, I am using a VR3 with a 4th cell currently to help track deco obligations. I dive a lot at 1500 - 1800 meters and that puts you into deco extremely quickly when you start getting deep.

Don't know if I understood it right, by multiple lvl profiles you mean (for example) you get down to 20m for some time, then to 50m for some other time, back to 20m for some time and finish the dive? (like in a cave?)
If this is the case, you can plan multiple lvl dives using v-planner. What version you are using?
Best,

Using 3.81. Found a bug while actually doing some multilevel simulations a few minutes ago. Just sent them an email to notify them and how to reproduce.

Like in a cave, but not normally in a cave. The only cave I ever do I've always only used tables for the dive.

What kind of bug did you find Ken?
Thanks,

Using the +- feature you can end up with memory crashes. They are looking at the error already. If you haven't seen the error yourself you will most probably not see it, unless I explained how to reproduce the error.
