Additionally, it would be an insult to compare amagnet with the upcoming mpg5 magnetic pulser Beck's). Can a magnet, when pulsed, be picked up on a magnometer(not certain if this is the proper name) from 20 feet away while being held? The magnetic pulser can. Deep penetration. Yeah, I believe it's got that!
I'm confident Russ T.'s mpg5 design will be a winner as the previous incarnations were.
Lapis has some very positive comments about this device. It supposedly can penetrate deep.
