If your kid wants to hunt ghosts, detect for spatial anomalies, or seek out interdimensional gateways, then this is the right toy for the job! Flashly warning light, cool sound, backlit, somewhat rugged design, affordable and best of all it is easily triggered. As for being an actual tool, well you know the old saying; "you get what you pay for".

i was surprised about the magnetic fields this thing let me track, thou i initially bought it to measure the volts per meter. sometimes the meter's display freezes up but the audible alarm still keeps functioning. simply turning it off and on again fixes this issue. it also had a light wich flickers when it beeps. at the price it costs i'm happy to 've finally bought it and learned from it

This EMR detector, while considered medium grade and is rather inexpensive, still performs well in the field and is suitable for most non-critical field work. If you are looking for something mid-grade for your tool box to carry with you out in the field, then I highly recommend the GM3120.
