Retrieving lost tags
Lotek NanoTags can be retrieved by manually tracking the tag with a Lotek handheld receiver. Since these receivers have a long range at full gain, it can take a long time to locate a tag that has been lost, but manual tracking is still routine for researchers . When touching the ground, the tag signal is modulated enough that a trained ear can actually identify the tag as being detached just by the quality of the audio signal the receiver emits.
Without a Lotek receiver you can use the open-source SensorGnome receivers instead, but they are much more difficult to use in this way since there is a longer time delay between when a detection occurs and when it shows up on the receiver’s display. Further, SensorGnome receivers do not offer a real-time gain adjustment, whereas Lotek receivers do.
