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 This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.motus.org/en/tags/appendix/tag-retrieval.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
