Anybody else notice this phenomenon with PI detectors?

Yesterday bumped into another hunter on the beach. When we passed each other, we both stopped to chat with our detectors still on. He had a Garrett PI machine, and maybe it was the same frequency as my Sand Shark, because my machine was giving me a pulsing sound in my headphones. The sound stopped when we continued on our way.

Anybody else ever experience this?

Yep. Happens with them all. Really hear that pulse beating when a VLF/Multi freq comes up on ya.

I have a CZ21 with a 10 inch coil and I cant get closer than 50 feet from the guys I hunt with. They have CZs with 8 inch coils. They can get much closer to each other without interference. I tell them the big 10 inch is sending out the power.

When I have the 12 x 15 on the Excal I'm in the same boat with a few of the guys I sometimes hunt with.....I can literally hear them coming.
