I was out detecting at a local school yesterday, and I noticed that my 5.5 x 10 coil kept drooping down and would not stay level. I went to tighten the nut, and I saw that both the ears on the coil had broken and the coil was just barely hanging on by the front part of the ears. I touched the coil and it just fell off of the rod. I had only used that coil for about 4 or 5 hours. Can anyone tell me who to contact for warranty service in the USA? I looked in the manual and on the Makro website, but I could not find anything. I am sure that Makro will replace it, since I had just purchased it on Nov. 6 of this year.
