This seems to mostly occur in periods of hot weather, but not always. We have developed a small add-on that screws into the nearby serial port that effectively holds the cards in place and will ship included with these loggers. Screw the device in firmly, then **gently** slide over a pre-inserted card. Take care not to force the depress the card inadvertently (although testing has shown it will still record). 241 +We have found that the older LPR SD card slots can sometimes fail such that the data cards prematurely "pop out" during recording, which can be catastrophic.
