The EM61HH-MK2A is a “hand-held” complement to the EM61-MK2A, providing greater sensitivity to smaller targets at shallow depths. A single 20 mm projectile can be detected to a depth greater than 0.5 m; a single 200 litre (55 gal.) drum can be detected to depths of greater than two metres.

With a narrower spatial focus than the standard EM61-MK2A, the EM61HH-MK2A is relatively less sensitive to sources of potential interference. As a result, data can be collected in closer proximity to cultural features such as fences and buildings. Additionally, the narrower focus provides for enhanced target resolution and, by consequence, improved discrimination of multiple targets.

Calculation of the decay apparent time constant, proportional to the ratio between early- and late-time signal response, allows for the identification of targets with similar physical characteristics such as material, size and shape; inherently, information is provided for improved target discrimination.

The EM61HH-MK2A can be operated either with or without wheels. In either mode of operation, the smaller, more portable design offers improved access to areas of particularly difficult terrain and dense vegetation.
