Timer and Radio Release Mechanisms

Capturing and recapturing for collar deployment is a stressful event for the animals and costly endeavour for the biologists. Lotek’s drop off solutions are designed to reduce the cost associated with recapture, as well as the stress on the animal. The choices offered can cover deployment on a multiple array of species. The weights of drop offs vary from 10g – 121g. The release principles include timer countdown, radio command for release up to 5 years, and release by Iridium command. Contact your Telemetry Specialist to discuss suitability of dropoff model for your study goals.


  • Choice of 3 drop-off mechanisms:
    TRD (Timed release device) drop off by timer countdown
    TRRD (Timed radio release device) drop off by timer or radio command
    TRRD-VHF (Timed radio release device) timer, radio or Iridium command
    On-demand triggering allows full control of release location.
    Units equipped with radio are also equipped with timer as a backup.
  • Either send existing collars to Lotek to be retrofitted, or do it yourself.
  • Compatible with most Lotek GPS and VHF collars.
