Here's what the law says:
"Using walkie talkies, cell phones, remote control or other radio equipment to take big game or small game is unlawful."
There is an exception for predators and crows for remote callers but it's pretty clear that for big game, it's a no-no.
PS. I just went to foxpro's site to see how they worded it. They have a few things wrong and have a few things that are too vague. I wouldn't rely on any internet postings or sites to describe rules or laws unless it's the DNR's page. (heck, I wouldn't even trust me in this thread. You really should look it up yourself and make your own decisions. ) I've discovered that calling St. Paul for the answers is really bad news. Those folks don't know a lot.
