Using off the shield patch cords with a certifier is a hit and miss thing. There is a reason that all of the established Manufactures of Certifiers use custom adapters with built in cables.

The Idea LanTack 2 Certifier is okay, but from the prices I have found I would still go with a Used Fluke DTX-1800
