Mini Mine Detector (MIMID)

Objective
Develop a handheld mine detector small enough to be carried on a deminer's waist belt, that can be used by the deminer in a standing, kneeling, or prone position, and with comparable performance as the AN-19/2 (PSS-12).

Description
The Mini Mine Detector (MIMID) is a battery powered handheld compact metal detector that fits into a belt-carried pouch and can be readily used for emergency extraction from mined areas. The MIMID can be set up for operation in less than thirty seconds. It is designed to detect buried minimum metal AT and AP mines. Its performance is comparable to the U.S. Army standard PSS-12 metal detector.

All controls are within easy reach of the operator and similar to those of the AN-19/2. The length of the telescopic shaft can be adjusted for operation in upright, kneeling or prone positions. The unique shape of the search head allows for better use in confined areas around buildings and in heavy vegetation.

Performance

In laboratory and field tests in Bosnia, Jordan, and Namibia, the MIMID has demonstrated nearly identical sensitivity and detection capability as the AN-19/PSS-12 metal detector in sandy, rocky, and highly magnetic soils. An advantage for deminers is the ease with which the MIMID can be transformed for use in the standing, kneeling, or prone positions by collapsing shaft sections. With a system weight of only 1.2 kg (3 lbs.), the unit can be carried easily at all times. The MIMID has a built in speaker, so that it can be used with or without headphones. The unit includes a visual display of light emitting diodes indicating intensity and providing a constant readout of the detection signal strength. This feature is useful for center determination of large metallic objects. The MIMID nominally operates 30 hours on 4 AA batteries. In laboratory tests the MIMID operated an average of 5 hours on four alkaline AA cells at maximum current draw before activating the low voltage alarm. The MIMID can accept auxiliary power input for operation from external supply, such as vehicle power, batteries or a solar panel. The MIMID units do not have mutual interference when they are operated 7.5 cm or more apart. The units maintained consistent detection sensitivity when tested for operation from +51°C to -32°C in high humidity, high altitude, and immersed operations in fresh and salt water.

Limitations

Reduced sensitivity in highly mineralized soils.
Water droplets on the detector search head must be dried off after immersed operation.
For best sensitivity performance, the MIMID should be operated with at least one shaft section extended.
