Altitude not correct…

Just checked some video against the logs on the device and the device was reading 300’ higher on the visual part at deployment than the logs show.

Is there any way to recalibrate 0 or anything?

It was always accurate until I went and jumped at the Ocean and came back, it didn’t get wet or anything.

I ask because I’ve been using it in my landing pattern and have noticed the last couple jumps I am significantly lower than the altimeter reads
