Keep pot holing until you find the problem.
my tricks on the locator are, thanks to jim and pete, isolate the wire path as best you can. pull out the common from the controller, the problem wire, the plug the ground, everything you can to get a direct path from locator to wire, to ground.
then, make sure you have a good ground contact. i like to turn my power up at the box and down at the reciever, others do opposite.
listen, listen, listen. thats prolly the most subjective aspect of locating. each site is different, so you really need to train your ear, (and eye for that matter) and note even the slightest change in tone.
and, when in doubt, pot hole. even the best have done it...
The 521 is not a good wire tracer, it's a good valve locator. I use my 501 more than the the 521 unless I'm looking for a valve.
i find valves with my tr-4110 @ 84k without problems, the 501 should do the same.
i use my 521s very seldom anymore. too many other cool tools to use
It does, but I can't get it to scream like the 521.
reorient the aerial from horizontal to vertical. irrigation valve locators are all vertically oriented to react loudly (peak response) with the solenoid coil.
Well I learned more about how to locate with my 521a, but what got the job done was potholing. Three holes and I ended up only "scabbing" in 45' of wire compared to 400' between valves. But im convinced there are better tools for finding a nicked wire than the 521a, not saying it cant be done, just that their may be a more refined or specific tool. Now I just need to get my boss to buy that tool
the best locator i have is me, everything else are jvst tools and accessories.
the trick to perfect locating is perfect practice and lots of it.
you can do a forum search for tempo progressive manual, download and memorize it. take note on connections.
i read everything i can on locating and i test test test. grounding is paramount. with a solid ground return path i can get 4 - 8 signal strength with minimal output enabling me to get better reception and greater distances.

Unfortunately, since the sprinklers have not been running it has been, as a maintenance guy once told me, "drier than a popcorn fart out there"
I think Wa state is one of the few areas without drought conditions.
