Crime Scene Metal Detector Operations will provide the crime scene investigator with a basic understanding of the nomenclature and operation of metal detectors. This course will also teach the techniques needed to successfully locate metallic items of evidence such as, but not limited to, firearms, projectiles, and shell casings. This training will permit the investigator to find more evidence and/or find the evidence more quickly.
?The design of this course is specific to the following metal detectors: Garrett CSI 250, Garrett CSI Pro, or the Garrett AT Pro. (For other metal detectors, please contact us.)
