Need some help from you "old timers"

Given an Ace 250 with a sniper coil, what effect would passing the coil over a magnet have? Found a signal in wood chips, which said it was about 4 inches deep. When I tried to pinpoint it, the detector was completely silent...nothing at all. When I passes the coil over it in a normal sweep, the signal was pretty spotty and intermittent but I decided to dig it anyway. Well, my digger came out with a fairly llarge, strong magnet attached to it, whcih was only about an inch deep, not 4 as indicated. I have to believe that the magnet affected the coil, but the funny part is, it's not the first magnet I've come up with, or even the strongest. I'm puzzled.

I guess it would depend on what it was made ofg. The rare earth ones would definitely read different then the fridge magnet type variety. I doubt if the magnetic field itself would change readings.

I find magnets in tot lots all the time and that's the way they react. The first time it happened, I thought my cellphone was causing the reaction.

Does it still work everywhere else?
