The Pulse Meter detects the heartbeat of enemy infantry, even when inside vehicles. The gadget must cool down after each use.
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.
- The Pulse Meter was intended to also detect the presence of Squad Leader Spawn Beacons, but this feature was cut.
