Low Temp

[dreslism]

When viewing the low temp for a dive, it shows 55 degrees, but sliding the cursor along the temp chart on the graph, the lowest that shows up is 57.
I also looked at the samples for this dive and it shows 57 as the lowest sample which matches the chart.

Where did the reported 55 come from?

Computer is a Shearwater Perdix Ai.

Samples are taken at a fixed interval, which is not necessarily the lowest value.

Nick, are you saying the low temp value is coming from the dive computer itself then, and not you determining it from the lowest sample value?

[nick]

Actually it depends on the specific dive computer. For some, various things like max depth/temperatures are not necessarily in samples but stored separately. In the case of the Perdix AI it does come from a sample, but the trailing surface samples are trimmed so it might have been found on one of those.
