[ RadSafe ] Victoreen 450

[M K]

Frankly, my experience with Fluke is WAY different..
I tried to get manuals/schematics for a couple of old Victoreen GC's.
Once I got the right person on the phone, I had the PDF's in my E-mail the
same day!
When you call any company, there is a art in how to speak to the staff, AND
getting the right staff person on the phone in the first place.
