Anyone break a coil cover yet? Just noticed this am , that a half moon section is breaking off outside under edge of my coil cover. Must had a rock impact. Must say, I have never broken one yet, in the last 6 yrs with prior Minelab machines. Wonder if ML will replace it, when I send in machine for display lines repair? Probably like a prophylactic, if they break, no warranty. Being funny obviously! Happy fathers day all!
