FOR HIGHEST RELIABILITY, ALWAYS CHOOSE THE LARGEST SIZE GEOLOCATOR YOU CAN USE. The smaller we make the loggers, the less robust they become and the higher the risk of failure due to damage. Also note that geolocators smaller than 2g may not survive temperatures below -10'C. However, geolocators that have failed in the field (or have reverted to the 'sleep' state during deployment) for whatever reason, can be sent back to us to attempt data extraction at no extra cost. Data is preserved for approx 20 years and can be accessed by us provided that no significant physical damage or corrosion has occurred. To accomplish this, you must have a note of the start of logging time and date (GMT) for each logger.
