SIGNAL ATLAS · PERIODIC TABLE OF SOUNDExplore the target register
221 active target identities. Search by recorded name, ID or target type.
Register, not a measurement library. Target names describe controlled reference identities. Physical specimen intake, measured detector responses and authorized audio are separate evidence. No sound, VDI or depth response is synthesized here. Historical identifiers are not reassigned.
Families follow the seven Sound Garden lanes
- Prospecting

- Historical / Hammered & Cast
- Beach & Jewelry
New finds use these lane families. The historical register below retains its recorded target-type descriptors while exact lane assignments are reconciled. Target IDs are preserved. Pool, Grail and White Reference remain separate.
