IMPORTANT: Versions with stalks and tubes will weigh more.
Expected lives are given, but please ask for specific warranty lives that vary according to the batteries used. Lifetime is from time of manufacture (the battery cannot be disconnected or replaced).
Please get in touch for help choosing the model and options required for your study see our contacts page.
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.
