Detector "Echo"

 is an item featured in S.T.A.L.K.E.R.: Lost Alpha. "The latest, experimental device, which according to the constructors should identify artefacts. Many mistakes have been made in the design, therefore it's not popular. The list of artefacts it detects is very limited."

- Inventory description

Overview
Contrary to Anomaly Detectors Anomalous Activity Detectors do not discover anomalies and radiation but artefacts.

To use an Anomalous Activity Detectors the player has to attach the detector to the belt first. Only one anomalous activity detector can be attached to the belt at the same time. Pressing O on the keyboard will put the detector into the player's left hand and activate the artefact search mode.

The Detector "Echo" indicates nearby artefacts by a beeping sound and a flashing light. The frequency of the beeps and the flashes is an indicator of the distance to the artefact, the closer the artefact is the higher is the frequency.

Upgrades
Upgrading the detector significantly improves the detection range and the number of detected artefact types.

Detector systems upgrade

Detector systems upgrade allows to increase its working radius.

Detection range +5.00 m

Detector systems upgrade

Detector systems upgrade allows to increase its working radius.

Detection range +7.50 m

Powerful antennas

New antennas almost double detector coverage thus enhancing its working radius.

Detection range +12.50 m

In v1.4005 Professor Kruglov needs data to do this upgrade, Professor Pirozhenko's records. The player automatically aquires this data upon completion of The expedition, when receiving the reward from Professor Pirozhenko.
