You will know when your too close. I use a CZ21 with 10 inch coil and I cant get within thirty feet of another CZ...The two guys I hunt with have CZ21s with 8 inch coils and they can hunt close to each other but cant get near me without interference.
I like to think that.That is because yours is supercharged.....
