HI Dana, and others. I talked to Magnum yesterday and they said there have been no upgrades really since new. ( my clients has serial # 136) Except better control of the search mode, around serial number 350.
This doesn't seem to jive with what a few others have said or my experience, but I guess that leaves no where to go with it. I also asked about upgrading it, and yes cheaper to buy a new one. If anyone else has any info I"m still interested, thanks jay peltz power PS if I get really motivated I"ll borrow an oscilloscope and test the old one vs a new one.
