I got mine in a pawn shop in DFW for 20 bucks
I have never seen another one used since - believe me, I've been lookin for em.
It works so simple - program the VOP (Velocity of propigation, the speed at which a signal will travel on that given line. almost all regular coax is 87 and quantum reach is 89) and then, just take the two alligator clips and hook one up to the housing and the other to the siezure screw assy (make sure you isolate which way it is going or you will get false readings)
It then gives you a # in feet to either a short (beep) or an open (no beep). It works great for reel inventory too!
I have also used it to tone out legs from an amp location. I shoot the legs and compare it to the footage on the map.
It's a beautiful thing.
