Pro Pointer w/12Khz machine

I'm looking at a Pistol Probe or a Pro Pointer. I noticed the Pro Pointer runs at 12 Khz. My main machine is a 12 Khz Treasure Baron Cointrax II. I'm wondering if they might interfere. Has anyone used one with a Baron or any other 12 Khz machine? I know some Tesoros are.
Thanks!
