Witric Power - Witricity Explained

I have 2 German shepherds. I have 5 acres of country plus 200 or more acres outside of that where they can run. recently :Jack" the male likes to go and run the farmers calves in a field next to our land. He wouldn`t hurt them it`s just the fun of the chase to him. He is young and playfull but a huge dog..We had a visit from the farmer the other day telling us he would be SHOT if found over there again. Can`t blame him I guess but now we have 2 german shepherds being confined to kennels when they have been raised running free and it`s killing them.

Basically, I am wondering about any problems that anyone might have with a specific brand or model.

I know that PocketWizards are "top of the heap", but I was wondering about other, less expensive units, and if they show problems with interference from things like large pieces of metal, high energy sources, line of sight issues, etc..., or any other problems you would like to share.

I appreciate any input you might have.
