One of my guys is at a customer that has a valve reading .3 Ohms and he's having trouble finding it. He's found every other valve on the site. I told him to go slow and that he's probably going to just lose the signal when he gets over it instead of it screaming at him and suggested he run a tracer wire down the lateral line to see if he can get to it that way. Anybody got any other suggestions besides poke, poke? Thanks.
