I have the Testo LanScaper kit for that kind of thing and really like. At a little over $400.00 though, it might be a bit more than you need.
It’s a great test kit though because it comes with 8 remotes so you can do up to do up to 8 jack ID, configuration and length tests consecutively back at the patch panel. This can really save a lot time and running around. It also has two different pin assignable tone settings for tracing wire pairs.
