Surprisingly first version of housing for tilt current meter did really great today. I took it down to 70 ft. Could see rubber cup intruding into the housing and bulging on handle of pvc insert cap behind it. But after I got back home and opened it no water was inside. That's great news. Next tests would be to:

- Take it down to 120ft for a few minutes

- Deploy it empty at 70ft for a week or so to make sure there is not significant material degradation happens
