The Independent Underwater Effector PDM-1B represents a new generation of devices for building defense barriers at a depth of up to 3.0 m at sea, lake or river watersides. They are designed to destroy all kinds of assault vessels including motor boats, light armor amphibious vehicles and others.
The device contains a unified non-contact fuse with three safety locks: transportation, mechanical and electronic to prevent unintended activation. After removing the first safety lock and submerging the device, the second safety lock is activated. The fuse has integrated magnetic and accousting sensors. Using specialized programming device, the duration of the armed state and target counter could be set.
The electronic block autonomously analyses the signals from sensor system according to pre-set complex algorithm and generates detonation command only if presence of target is detected above the mine. The fuse cannot be activated from humans and marine life.
The system also has two programmable modes for termination of the armed state after expiration of the pre-set time – self-destruction or neutralization.
If the mine is neutralized, the fuse separates from the warhead and emerges to the surface. The mine could be retrieved and fuse could be factory refurbished in order to restore the functionality of the system.

Optional system
Option: A Remote Control System can be employed to control the device from the coast or from a vessel. The system performs the following functions:
- Activation;
- Deactivation (neutralization or self-destruction).
The commands to the Remote Control System are transmitted from a control station. Each sensor system has an individual coded access number, which allows sending control signals to each device, to separate groups of devices or to all devices of an anti-landing barrier within the range of control system.
