More Uwatec Aladin TEC2G Log Data
by Thomas Gschwind 02 Jun '17

Hi there, I am using Subsurface and it reports all my salt water dives deeper than they really are. So I downloaded the latest libdivecomputer sources and looked at the code. The tec2g_header claims that the salinity setting of this dive computer is not supported. After looking at the dumps included in my SmartTRAK log where the dives are correctly reported (SmartTRAK is nice enough to store the original dc data), I am most certain to have located the salinity field in byte 62 of the header. Another indication is that it is also bit 0x10 as it is for the others (see get water in uwatec_smart_parser_cache). Just tried out setting the salinity field to 62 and works perfectly fine for me. Similarly, the timezone field most likely is 16. However, that one I cannot test so well because the immersion time seems to be relative to the dive computers system time which seems to be missing in the SmartTRAK logs. But manually looking at the time zones, it matched for the first 50+ of my dives. I also figured out the max ppo2 configuration and partially the tissue saturation before the dive --- if anybody is interested that data as well. See http://tomsblog.gschwinds.net/2016/08/uwatec-smarttrak-and-aladin-tec2g/ for details. Best, Thomas

shearwater Perdix AI

I have in my greedy little hands a Shearwater Perdix AI computer, which Shearwater says shares the same firmware with the Perdix and the Petrel, but it will have air consumption (if equipped with a sender). Is there anything I can send a developer that would help with support or this? I didn't see it in the list of supported computers. Thanks! -jon
