Hello All,

I’m America based scientist exploring the use of hydro moths as a way to monitor oyster restoration and eelgrass restoration. We order two back in June and have had them deployed ever since. We let them run for two weeks before servicing them. During our check one was found with the latch pop open. There was very little water inside and the unit recorded the whole time. The second unit was fine. We decided to put a zip tie around the two units to help keep it closed. After 3 weeks we check them again and both units where open. The zip ties slipped from being over the latch. Does anybody have any ideas on why this might happen? Is there a different case that would be more suitable for coastal intertidal work? One unit is completely lost. The other unit appears to be working. But with this I don’t know if it is useable long term. The seal also seem to be easy pinch and not seal correctly. Im also worried about biofouling over time. Any ideas would be most appreciated. We have gotten some great data and I would really like to make this work.

The first photo is after two weeks, before we used the zip tie on the latch. The last two is of the lost unit.
