Hi there . I have been detecting just over 2 years I have awsome finds from all ages roman , saxon etc.
I brought the coiltek 15 in the pinpointing is off I have all 3 minelab coils I had tiny hammered coins among iron all my finds have came from the minelab coils and the coiltek 15in is 300 gram heavier than the minelab so over few hours you start to feel it in your arms lol . So my personal view on the coiltek is no real difference in depth with minelab so my moto is dont fix that isnt broke so finding loads with minelab coils .
