In the last couple of weeks I've seen a couple of threads about techs needing a decent tester/certifier. Since I'm strictly doing the wed design thing now, I no longer have a use for this one.
Here's the story on it. I've had this unit for about 4 years. I purchased it for a large 80 camera installation we did. I used it to test about 10 long lines, put it back in it's case, and there it's sat ever since. I paid about $450 for it new. I'd take $200 + shipping if it helps someone out...As you can see, this thing doesn't have a mark on it. You download software from their website if you want to do certification. It's a nice little tool.
Byte Brothers Real World Certifier is the model.
