Not exactly the same, but when I’ve been on a lake and sense that other parties are trying to figure out where I’m fishing, I’ve been known to set a marker buoy in a place that, if there are fish present, they will be hammerhandles or juvenile bass.  ;D I will leave it there, in sight of my Camp, of course, as it provides great entertainment and humor. ;D Of course, the optimal set up is, if they come by and ask about the fishing, is to hold up a nice stringer, and point to the general area of the lake where they will find the marker.  ;D

Is that what you take markers for!
