WallFishing is as easy as the tools you have to do it with.
I myself have just ordered the
MagnaFish. When I get a chance to use it Ill be sure to post back. Its pretty expensive( $80-$100.00) but if you are a contractor and getting paid by the fish and not the hour you can definately get more work done in less time.

Below is a simple preview of how it works. The hardest part to me of doing a wall fish is the need to be in two places at once most times. Fishing down or up is always easier with two sets of hands and eyes.
Without the right tools you can climb in and out of an attic 8-10 times trying to get your line where it needs to be and locate it inside the wall. There are of course cheaper alternatives that would work just as well.
Drill hole, insert heavy metal hanger into wall cavity.
Go into the room and use the magnet to locate the hanger.

Slowly pull the hanger down to the hole.

When you get to the hole the hanger should pull out when
it slides off the wall and onto the magent.
Then remove the hanger and attach your line to pull up
or if you have attached your line to the hanger you are done!

Theres no reason you couldnt buy a large industrial magnet and make one of these for a lot less. But this one comes with a real Neat-O case.
