The Scent Transfer Unit allows law enforcement to collect evidence from any item without destroying fingerprints on the item, collect trace evidence at a crime scene without contamination, collect scent evidence from hard to access places not accessible to a search dog and gives law enforcement a scent pad to store in scent banks for future use on repeat offenders.
