Find concealed phones, even when switched off
Manta Ray from Berkeley Varitronics Systems is a close-range ferromagnetic cell phone detector. It helps screen people, bags, packages and potential hiding places in correctional facilities, secure buildings and controlled areas. Detection does not require the phone to transmit a radio signal.

The detector responds to ferromagnetic phone components. The manufacturer also specifies detection with the battery removed; the cellular network or flight mode does not change this detection principle.
Two modes Handheld and stationary screening
In handheld mode, move the detector smoothly along the area being checked. In stationary mode, keep the detector still and move the item in front of it.
Alerts See and hear a detection
A colour TFT display, flashing blue LEDs and an audible signal help identify a trigger. The display indication helps you recheck the area of interest.
What is Manta Ray designed for?
Primarily for close-range searches for concealed mobile phones. It can also respond to other electronics or objects containing detectable ferromagnetic material. It does not guarantee detection of every metal or every type of contraband.
Ranges are indicative. Detection depends on the object, orientation, battery condition, movement and environment. When scanning through a wall or package, its thickness counts towards the total distance to the phone.
Screen in three steps
- Prepare the detectorInsert a 9 V battery and hold the orange trigger. Handheld mode starts in approximately 5 seconds; test with a known phone before use.
- Sweep smoothlyMove up and down or side to side, parallel to the surface. Do not twist or tilt the detector. Keep it close to the item being checked.
- Confirm the alertWatch for the display crosshairs and blue LEDs and listen for the beep. Repeat the scan and investigate the cause according to your screening procedure.
Choose the correct operating modeStationary mode requires the supplied adapter, approximately 15 minutes of warm-up and around 3 seconds of calibration. The detector must remain still. Iron, steel, environmental interference or overly fast hand movement may cause unwanted alerts.

Frequently asked questions
Can it detect a phone that is off or has no battery?
Yes. According to the manufacturer, Manta Ray can detect phones that are powered off or have their battery removed. It detects ferromagnetic components, so active cellular, Wi-Fi or Bluetooth transmission is unnecessary. Test each situation in practice.
What is the detection range?
The manufacturer specifies 0–6 in (approximately 0–15 cm) in handheld mode and 0–12 in (approximately 0–30 cm) in stationary mode. This is close-range screening; results depend on the object and environment rather than room size.
How do handheld and stationary modes differ?
In handheld mode, move the detector along the area being checked. In stationary mode, keep it firmly in place and move the item in front of it. Stationary mode requires the adapter, approximately 15 minutes of warm-up and around 3 seconds of calibration.
Can it find a phone behind a wall or inside a package?
The manufacturer demonstrates detection behind aluminium, concrete and other materials. This remains a close-range check: wall, lining or packaging thickness is included in the distance to the phone. Ferromagnetic structures and environmental interference can make screening more difficult.
Can keys, buckles or other metal objects trigger an alert?
Yes. Although ferromagnetic detection can reduce some triggers associated with conventional metal detectors, certain metal objects, particularly those containing iron or steel, may still trigger an alert. Recheck the area and determine the cause.
Is this a universal weapon and all-metal detector?
No. Its primary purpose is phone detection through ferromagnetic components. It may respond to some weapons or other objects, but it does not detect all materials or replace a complete security screening procedure.
How long does it run, and can I use rechargeable batteries?
The stated runtime is up to 3 hours of continuous operation on a standard 9 V alkaline battery. The manufacturer also supports suitable 9 V rechargeable Ni-MH and lithium-ion batteries; runtime varies. Replace the battery when the LOW indicator appears.
Why does the scanning movement matter?
Handheld mode needs a smooth up-and-down or side-to-side sweep. Holding the detector still may produce no detection, while sudden twisting or a very fast sweep may trigger a false alert. Scan parallel to the surface and repeat the check.
