# Retrieving lost tags ## Manual tracking basics Coming soon... ## 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. \[Insert information on CTT Tags] \[Insert methods for retrieving tags] --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.motus.org/en/tags/appendix/tag-retrieval.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
