They will all work but only the FoxJack will plug into the auxilary port to operate it remotely. I quess you could rewire any of them to to use thauxilarry port. I think the auxilary post is basicly an on/off switch but is limited to a pretty light load probly not more than the Foxpro decoy load. I know some that have modified bird decoys to work off the auxilary port.
I like decoys, others hate em, I just leave them running through the whole stand and haven't seen a problem.
