LAT2000 Series – Light Geolocation

  • Product Type Icon Tag

Gain valuable insights into the life cycle of your species.

Lotek Archival Tags (LAT) are compact, reliable instruments for collection and storage of precision-time-stamped depth, temperature and light-based geolocation data.


  • A selection of pressure ranges are available for each tag to ensure the best match for every application.
  • Four memory management (log type) options: Day Log, Telescopic Log, Conditional Log, Basic Log.
  • Internal and external temperature sensors are available
  • Product Applications

    LAT, light geolocation archival tags are the ideal data storage solution for any biologist seeking reliable long-term life-cycle-related data for fish, wildlife or avian species.
