I just bought my d4i last week and used it in a 16m pool to freedive. It worked fine.
Today i took it to open water and depth showed around 10m in my first two dives, which is correct. But on my third to fifth dives, it showed around 200m, which is impossible because i dive to only about 20m. On my seventh and eigth dives it just shows blank (_ _ _ m).
Anyone knows what i did wrong?

Also it has been 4 hours since i got out of the water and the surface time wouldn't stop counting. Is this normal?
I know sunnto had a huge recall due to the depth sensor. I would check with their customer service and have then run your serial number
