This is the log comparison for the Nautic and the EON Core on the same dive this morning 23/08/2026 +/- 9 AM. I didn’t sync the EON Core before the dive, that explains the hour difference as last dive was in the winter.
NOTE:
1 Single POD (Left on my 1st Stage)
Nautic (New Firmware) on my Left Arm
EON Core on my right arm
That’s the real story here — these two logs are from two entirely different dive computers, not the same device on different dives. That changes what “logging accuracy” comparison actually means.
Device identification:

Assessment:
The EON Core log is more accurate/reliable: higher ventilation coverage, tighter and more consistent co-logging of pressure with ventilation, zero dropout events, and a cleaner sample cadence.
The Vaasa log has real data-quality issues: 10 zero-ventilation dropouts mid-dive at depth (physiologically implausible), a lower field-coverage rate, and a stray 0.0-second duplicate timestamp — all consistent with the sensor/logging quirks flagged in the earlier Vaasa-only analyses.
Both devices measure ventilation on the same order of magnitude and unit scale, so the underlying sensor readings are comparable — the difference is purely in how completely and cleanly each device logs the field, not in what it’s measuring.
Bottom line: if you’re trusting ventilation data for analysis, the EON Core’s log is the more accurate/complete of the two; the Vaasa log needs the dropout samples filtered or interpolated before use.
