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.
Long battery life: Units may be released on command or set for release up to 60 months from moment of deployment.
