Given the first dive calculates it correctly, it seems like it could be related to the surface interval.I think there is a problem in the firmware of the i300c dive computer on how it calculates the average depth for the dives... and the dive log shows the wrong average depth. Here is an example for my last 6 dives:
Code:# Start Time End Time Date Pre Dive Surface Interval Max Depth (m) Dive Time Average Depth (m) 6 13:49 14:28 06-Sep 00:22 8.9 33 0.6 5 12:43 13:27 06-Sep 23:50 7.4 43 0.9 4 11:51 12:48 05-Sep 00:31 12.9 57 2.7 3 10:29 11:19 05-Sep 21:52 21.9 50 5.6 2 11:40 12:32 04-Sep 00:28 15.9 52 5.5 1 10:26 11:11 04-Sep 21.3 44 16.8
The only accurate average depth is for dive #1... all the rest are wrong until the dive numbering is reset again, when the first dive is correct and the rest appear as if the computer includes the surface interval or some other values in the average making the average go down and down, regardless of the actual recorded maximum depth and dive profile.
For the example above, the correct average depth should have been as follows:
Code:# Average Depth (m) 6 5.1 5 4.7 4 9.3 3 16.4 2 10.1 1 16.8
Is this a bug in the firmware or I am not understanding something correctly on how the computer should calculate the average depth for each dive?
after the dive finishes, does it immediately go back to predive mode?
Edit: I figured out what the computer is doing. I need to figure out how to post it. One second.
