my GP4000 can't handle my 24 inch Coiltek DD, just goes off all the time like detecting a minefield, works fine with the 3000 and others........................

GP4000 CAN'T HANDLE BIG COILS Empty My 4000 can't handle big coils

Claimpeg,
My 4500 wouldn't handle big coils, it kept coming up coil overload on the screen but the same coil worked fine on the mates detector.
I sold the 4500 and bought a 400 and use any coil without a problem.
I rang Minelab about it and they said it was a coil fault , don't make sense to me.

I've run the Coiltek 24"DD, the Nugget Finder 20" mono and the Coiltek 24" x 12" UFO on my old 4000 with no problems. I currently favour the 20" NF mono or the 25" NF mono on my 4500 whenever the terrain allows me to run them, and have never had a problem. I've also used an 18" Coiltek salt coil, a 14"x9" NF mono and a 16" NF mono on my 4500. Maybe it has to do with the coils parameters as to whether it suits a particular machine as they are all supposedly slightly different. Cheers.

Is that a 24x12" DD Big Red or a round 24" DD you are talking about?

The only problem I had with a coil was back years ago with my 2100 or 2200 when I had a very large round custom round 30" or 36" off of Bob Garbutt that would not work properly and I could only use it on one channel. But I ran a round 24" DD and it worked just fine on my 2200.
