I've been doing a lot of remodels lately and I always get stuck with moving the phone lines and putting them back together after the demo crew cuts thru them. Right now I am using a cheap plug in tester plugged into an old jack with two wires sticking out to locate the signal!

Can any of you guys recommend a tester I can get for locating which pair carries the signal, and can also tone out pairs from downstream jacks?

Also, for indoor use, what can I use for good splices? The Scotch locks are a real pain.
