Nagyon jó ár-érték arányú termék. Köszönöm!

Nice kit, with included schematic

Easy to assemble. The line is a bit thin between “too sensitive” and “doesnʼt detect a thing”, but finally found the correct position of the potentiometer so it works. The kids love it already.

The project is for education purposes, do not expect more than 30mm finding depth. Excellent learning tool about interference. Kids love it.

Pleasant and easy to build (soldering iron needed). Works as expected but do not expect to detect metal at a distance exceeding 5 - 10 cm.

very compleet, works okay but only at close range.

ok?

still have to build the kit

This was so much fun to make and learned a lot soldering this up. Would buy again
