With growing number of deaths of its troopers in blasts – a new strategy adopted by Maoists – in the last few years, the CRPF is in the process of upgrading their Improvised Explosive Device (IED) detection equipment and Bomb Disposal Squad (BDS) unit to avoid casualties of their troopers in the Maoist - affected areas.
These equipment are very sensitive detectors and are capable of tracing hidden analogue and digital signals which are frequently used for ignition of IEDs and land mines, a source close to the anti - Maoist operations in Chhattisgarh's Bastar region told IANS.
The equipment, with light in their size, have a crystal detection sensor for detecting conducted circuits commonly found in IEDs and radio transmitted wireless devices, he said.
"The can capture frequency possible even through solid materials such as walls, bricks, glass, plastic, concrete and wood. "
Up to a distance of 120 cm, the equipment are able to detect the IEDs which offers an increased level of safety, said the officer, adding they are also designed to detect waves of mechanical count - down timers and cell phones in improvised explosive devices such as mechanical timing devices.
According to the official, an integrated display at the detection head of the equipment show the results found during the operation.

They have the working capacity of 24 hours.
Stereo headphone attached to these equipment are high - sensitive in catching frequency range. "
Besides, the CRPF is upgrading its BDS units that includes sniffer dogs, said the official.
He said the BDS team is being trained with new ways of planing IEDs and the number of sniffer dogs are being increased.
