  • LAT 2000 Geolocators

    Built upon the success of several previous generations of Geolocators and Temperature/Depth recorders, Lotek Archival Tags (LAT) offer impressive data recording capabilities in a very compact design. LAT 2000 Series Geolocators (light-based tags) are the ideal data storage solution for any biologist seeking reliable long-term life-cycle-related data for fish, wildlife or avian species.

    Two distinct LAT families are available: LAT1000 Series TDRs (time, temperature and depth recorders), and LAT2000 Series geolocators (light-based tags, this page).

    • A selection of pressure ranges is available for each geolocator tag to ensure the best match for every application.

    • LAT geolocators feature user selectable data resolution settings of up to 12 bits. Opting for a lower resolution allows an increase in the number of samples collected.

    • Up to 128 Mbytes of non-volatile memory are available on specific models.

    • The LAT series features a sea water switch.

    • Four memory management options are available on LAT geolocators:
      1. Day Log: summarizes on board geolocation and other processes, allowing one to collect data for every day at liberty; a number of “loggables” are available to be recorded in the Day Log, e.g., daily: sea surface temperature, min. and max. pressures, min. and max. temperatures, times of sunrise and sunset, etc.;
      2. Telescoping Log: allows the total times series storage capacity of the tag to be evenly distributed over the entire mission.
      3. Conditional Log: samples recorded (or not) based upon the condition of one or two sampled “loggables”;
      4. Basic Log: straight sampling.
    • LAT geolocators are designed for miscellaneous data collection and data compression strategies aimed at maximizing and optimizing tags' operating life and number of samples taken.

    • All LAT Geolocators use a USB reader and a communication interface, LAT TagTalk. The reader is practical for field work as it connects to the tags’ gold electrical contacts using minigrabbers – this method is very stable and reduces the risk of interfering with the connection if the tag is moved. The software allows the user to interact with the tag, to create a flexible programming regime and to download the data from the geolocator tag.
