Detector assembly

Vitya the Hologram will agree to give you his two remaining Ultra-detectors in exchange for two simpler Advanced Anomaly Detectors plus a Plasma Caterpillar.
== Walkthrough ==
Advanced Anomaly Detector can be bought from Sakharov for 50000RU; he has 1 item per day in his stock. Alternatively, it can be obtained for Kruglov's Priority 3 cyclic quest to bring him certain artifacts.
After obtaining both detectors and a Plasma Caterpillar, bring them to Vitya. Ask Cyclop to use his psychic powers to tell you where the stolen Vitya's stash is. He will answer with a riddle:
In the roots of a faded giant
A good secret is hiding
Yonder, where the blind scurry about
Between the glowing rubbish and the hill
That is closest to the Valley of Lawlessness
Strelok, I'm sure you know this place perfectly well...
Cyclop is talking about the dead tree at the Dump, near which a pack of dogs lives.

* The task description says that "elite" detectors are required; this is a localization error, and he needs Advanced ones.
