DysTek Pulse Meter

The DysTek Pulse Meter is an unlockable gadget featured in Battlefield 2142, available to the Support kit after unlocking the IPS Shield and Advanced Ammo Hub.

The Pulse Meter detects the heartbeat of enemy infantry, even inside vehicles. The gadget must cool down after each use.

Located enemies are 3D-spoted in the player's NetBat Helmet and those of squadmates. Other team members do not benefit from the detections. The red diamond indicators do not track their targets, unlike regular spotting; the user must anticipate the target's possible movement. The indicators disappear after a few seconds.

A similar function is provided by the RD-4 Otus squad leader drone.

Trivia

 * The Pulse Meter was intended to also detect the presence of Squad Leader Spawn Beacons, but this feature was not actually implemented in the release version of the game.
