Metal detectors

I’ve been eyeing for one for some time.  I need a hobby to encourage me to move and loose belly fat yet without clashing with my laziness. Roaming depopulated countryside with a metal detector seems like a plausible option. Yesterday my search took me to the Moscow Hobbies Fair, where I stumbled into a seller who knew his stuff and was willing to explain how metal detectors work and what’s the difference between dozens of models to a novice. Not something sales people commonly or willingly do here. That’s why I’m sharing this info with you:

Miskovskaya Yarmarka Uvlecheniy (Moscow Fair of Hobbies)
Ulitsa Krasnobogatyrskaya 2, stroyeniye 2, section 59
+7 495 648 6961 (Sergey)

Something to add?
