Manta Ray™ is the answer to the growing problem of unauthorized, illegal, unsecure & contraband cell phone use in correctional facilities, government buildings, corporate environments, financial institutions, universities & law enforcement agencies. Berkeley's unique cell phone detection device is a close range TSCM security scanner for concealed mobile phones (ON or OFF and even with battery removed). Manta Ray™ differs from traditional metal detectors in that it scans for specific components common to all cell phones and not just metal. This reduces false triggers* such as watches, keys, coins, belt buckles and other common metal items that may trigger a standard metal detector. Manta Ray™ is the perfect tool for any security detail tasked with rapid scans of many targets including people, packages, bags, briefcases, purses & more. Manta Ray™ supports both HANDHELD and all new STATIONARY mode for ultra-sensitive package inspections. Manta Ray™ is designed and manufactured entirely in the U.S.A..

Does Manta Ray detect knives or guns?

Manta Ray can detect some knives but is designed to be one part of a more complete security detail that includes metal detectors, armed guards and explosive material detections. Manta Ray may be triggered by some metals but is primarily used to eliminate the presence of a cell phone before more exhaustive or invasive searches are performed.
