4.0 out of 5 stars
Simple but effective...,

This review is from: EVP Listener
A simple yet effective magnetic induction pickup. The 'receiver' is nothing more than a telephone pickup coil connected to a mini speaker amplifier. Telephone pickup coils 'pick up' the sound via the electromagnetic disturbance around the earpiece. This is a much better deal than buying these items at the famous shopping mall radio store...The only problem I see with this would be a steadily changing DC current may be hard or impossible to detect. You can clearly hear audio speakers and AC (house wiring) disturbances because it is modulated. Unmodulated steady EMF fields that would drive a meter above 10 may not be very noticeable as an audio signal. EMF meters use the same type of pickup. However, since steady fields may not be audibly detectable, it's best used in conjunction with an EMF meter. This is an excellent way to monitor any fields for audible modulation. If you have a digital (or micro-cassette) voice recorder, the pickup coil can be plugged directly into the "Mic" input.

Worked fine and very responsive, but.. after about 90 days it failed picking up any sound whatsoever, checked battery and internal connections no obvious damage. for the price it's ok, but for any long term use I'd spend more.

Amazon Verified Purchase(What's this?)
This review is from: EVP Listener
This is not a bad price, however it is a little cheaper at RadioShack. You don't get the pickup or the headphones if you go to Radioshack unless you pay extra. I received mine pretty quick after I ordered it. The reason I only gave it 3 stars is because mine was not very loud at all. I could barely hear it when it was turned up all the way. I tried an expensive microphone with it and heard close to nothing. The magnetic pickup it comes with is an inexpensive model, but it should still serve its purpose. When I used it around my electrical sockets, I could hear a faint sound even when the volume was turned all the way up. I believe this defect is from the factory. There was no evidence to suggest that the model I received was used or even damaged in shipping. I very well could have been damaged in the shipping, but it seemed to be packed pretty well. I had purchased it for the very reason it is advertised here. This is not the only Item I use, in fact I only bought it because of what it claims. I trust my wide array of other tools like digital recorders, FranksBox, and my EVP detectors.
